DOCUMENT REVISION HISTORY
Revision A (October 2022)

• Initial release of this document as Microchip DS50003423A.
  Revision B (September 2023)

• Revised for software release 1.1 with support for 5071A and 5071B cesium instruments.

Chapter 1. Introduction

1.1 PRODUCT DESCRIPTION
The Clockstudio™ software is a standalone graphical user interface (GUI) intended for communication and control of Microchip Atomic Clock products. It allows a user to quickly familiarize themselves with the capabilities of these products rather than entering text-based commands via a primitive command line interface.
The charting capabilities are a powerful tool for experimentation and investigating device performance under specific conditions.
See the Appendix section: Supported Instruments for a list of supported clocks products.

1.2 PRODUCT FEATURES

• Communicate with multiple devices via a single interface
• Configure device settings (Frequency, 1PPS Disciplining parameters, Time of Day, etc)
• Monitor “real-time” device telemetry in tabular form
• Display device telemetry as a chart
• Load and display previously saved data
• Import data from other text-based files
• Export data for further analysis (such as Microchip’s TimeMonitor software tool)

1.3 BASIC GUI LAYOUT
When the application is launched, the user will see a Start tab in the main window with the File menu above it (Figure 1-1). From here, a user can decide to connect to an atomic clock or open an existing data file. This action will open a new tab with four main areas:

• On the left side is a Toolbar menu
• The right side (main portion of active tabbed window) will present a different view dependent upon the tool selected from the toolbar
• North Region – The top part of the tabbed window contains the Title bar
• South Region – The bottom part of the application window contains the Status bar

Chapter 2. Operation

A user primarily interacts with the application via mouse (such as selecting from drop-down menus and toggling radio buttons) and secondarily with the keyboard (to set device-specific parameters or enter commands via the console feature, for example).
The application was designed to run on Windows 10 and 11 based systems.
This User Guide divides the GUI in to eight main features, described in the following sections:

• File menu: describes file loading and saving
• Settings menu: lists modifiable Clockstudio™ application settings
• About menu: contains general Clockstudio software version information
• Start tab: initiate communication with a device, open a file, or link to a product sup- port URL
•  Title bar: overview of the connected device
• Toolbar: lists available interactive features of a device
• Status bar: contains the console along with active data file information
• Charting: description of how to plot telemetry parameters

2.1 FILE MENU
The File menu is always present at the top of the application and contains a number of file operations, as described in the below sections. The Clockstudio program uses file extension .ctdb for data files. New data files are created whenever a new connection is established and they are saved in the following Windows directory by default:
C:\Users\\Documents\Clockstudio
The directory and other data file acquisition options can be modified. See Preferences for more information.

2.1.1 Open Telemetry…
Opens a file browser to select a previously saved file for analysis. When a file is opened, a new tab appears in the Clockstudio application, labeled with the filename.
The Title bar, Toolbar, and Status bar will also populate in this tab. Supported extensions are .ctdb, .csv, and .phd.

2.1.2 Open Recent
Displays a list of recently opened data files.

2.1.3 Export Telemetry…
Files may be exported in .csv format or also in a .txt format readable by Microchip TimeMonitor software.

2.1.4 Rename Telemetry…
Available when connected to a device. This feature is useful for moving the data file during an active data capture.

2.1.5 Quit
Exits the Clockstudio application.

2.2 SETTINGS MENU
The Settings menu is always present at the top of the application and contains the Preferences tab.

2.2.1 Preferences
The Preferences tab allows a user to adjust the telemetry capture settings. Default settings can be adjusted, including the location for storing data files,  file naming convention, and the polling rate.
Visual display settings can also be adjusted, including chart density (resolution).

SOFTWARE LICENSE AGREEMENT
This Software License Agreement (“Agreement”) is an agreement between you (if licensing as an individual) or the entity you represent (if licensing as a business) (“you” or “Licensee”) and Microchip Technology Incorporated, a Delaware corporation, with a place of business at 2355 W. Chandler Blvd., Chandler, AZ 85224-6199, and its affiliates including Microchip Technology Ireland Limited, a company organized under the laws of Ireland, with a principal address at Ground Floor, Block W., East Point Business Park, Dublin, Ireland 3 (collectively, “Microchip”) for the Microchip software and documentation included in the download or otherwise provided by Microchip to Licensee (collectively, the “Software”).

1. Use. Subject to the terms of this Agreement, Microchip hereby grants Licensee a limited, revocable, non-exclusive, non-transferable, worldwide license to (a) use the Software, and (b) modify the Software provided in source code form, if any (and use and copy modifications of such Software made by Licensee), provided that in each case (with respect to clauses (a) and (b)) Licensee solely uses the Software with Microchip Products, Licensee Products, or other products agreed to by Microchip in writing. Licensee has no right to (i) substitute third party products for Microchip Products, or (ii) except as expressly provided in Section 2 below, sublicense its rights under this Agreement or otherwise disclose or distribute the Software to any third party. Licensee may make a reasonable number of copies of the Software solely as necessary to exercise its license rights in this Section 1. Licensee will not remove or alter any copyright, trademark, or other proprietary notices contained on or in the Software or any copies. “Microchip Products” means those Microchip devices purchased from Microchip or one of its authorized distributors that are identified in the Software, or if not identified in the Software, then such Microchip devices that are consistent with the purpose of the Software. “Licensee Products” means products manufactured by or for Licensee that use or incorporate Microchip Products.
2. Subcontractors. If Licensee wishes for its subcontractor to obtain and use the Software in order to provide design, manufacturing, or other services to Licensee: (a) such subcontractor may (i) download and agree to the terms of this Agreement or (ii) contact Microchip directly for a copy of this Agreement and agree to its terms; or (b) Licensee may sublicense the rights described in Section 1 directly to its subcontractor, provided that (i) such subcontractor agrees in writing to the terms of this Agreement – a copy of which will be provided to Microchip upon request, and (ii) Licensee is liable for such subcontractor’s acts and omissions.
3. Third Party Software. (a) Third Party Materials. Licensee agrees to comply with third party license terms applicable to Third Party Materials, if any. Microchip will not be held responsible for Licensee’s failure to comply with such terms. Microchip has no obligation to provide support or maintenance for Third Party Materials. “Third Party Materials” means the third party software, systems, tools, or specifications (including those of a standards setting organization) referenced in, bundled with, or included in the Software. (b) Open Source Components. Notwithstanding the license grant in Section 1 above, Licensee acknowledges that the Software may include Open Source Components. To the extent required by the licenses covering Open Source Components, the terms of such license apply in lieu of the terms of this Agreement. To the extent the terms of the licenses applicable to Open Source Components prohibit any of the restrictions in this Agreement with respect to such Open Source Components, those restrictions will not apply to the Open Source Component. “Open Source Components” means components of the Software that are subject to the terms of an Open Source License. “Open Source License” means any software license approved as an open source license by the Open Source Initiative or any substantially similar license, including without limitation any license that, as a condition of distribution of the software licensed under such license, requires that the distributor make the software available in source code format.
4. Licensee Obligations. (a) Restrictions. Except as expressly permitted by this Agreement, Licensee agrees that it will not (i) modify or alter the Software or a Microchip Product; (ii) adapt, translate, decompile, reverse engineer, disassemble the Software provided in object code form, any Microchip Product, or any samples or prototypes provided by Microchip, or create derivative works thereof; or (iii) use the Software with any software or other materials that are subject to licenses or restrictions (e.g., Open Source Licenses) that, when combined with the Software, would require Microchip to disclose, license, distribute, or otherwise make all or any part of such Software available to anyone. (b) Indemnity. Licensee will indemnify (and, at Microchip’s election, defend) Microchip from and against any and all claims, costs, damages, expenses (including reasonable attorneys’ fees), liabilities, and losses, arising out of or related to: (i) Licensee’s modification, disclosure, or distribution of the Software or Third Party Materials; (ii) the use, sale, or distribution of Licensee Products; and (iii) an allegation that Licensee Products or Licensee’s modification of the Software infringe third party intellectual property rights. (c) Licensee Products. Licensee understands and agrees that Licensee remains responsible for using its independent analysis, evaluation, and judgment in designing Licensee Products and systems and has full and exclusive responsibility to assure the safety of its products and compliance of its products (and of all Microchip Products used in or for such Licensee Products) with applicable laws and requirements.
5. Confidentiality. (a) Licensee agrees that the Software, underlying inventions, algorithms, know-how, and ideas relating to the Software, and any other non-public business or technical information disclosed by Microchip to Licensee are confidential and proprietary information, including information derived therefrom, belonging to Microchip and its licensors (collectively, “Confidential Information”). Licensee will use Confidential Information only to exercise its rights and perform its obligations under this Agreement and will take all reasonable measures to protect the secrecy of and avoid unauthorized access, disclosure, and use of Confidential Information. Such measures include, but are not limited to, the highest degree of care that it uses to protect its own information of a similar nature, but not less than reasonable care. Licensee will only disclose Confidential Information to its employees, subcontractors, consultants, auditors and representatives (collectively “Representatives”) who have a need to know such information and who have use and confidentiality obligations to Licensee at least as restrictive as those set forth in this Agreement. Licensee is responsible for disclosure or misuse of Confidential Information by its Representatives. Use of Confidential Information for personal gain, for the benefit of a third party or to compete with Microchip, whether directly or indirectly, is a breach of this Agreement. Licensee will notify Microchip in writing of any actual or suspected misuse, misappropriation, or unauthorized disclosure of Confidential Information that comes to Licensee’s attention. Confidential Information will not include information that: (i) is or becomes publicly available without breach of this Agreement; (ii) is known or becomes known to Licensee from a source other than Microchip without restriction and without breach of this Agreement or violation of Microchip’s rights, as demonstrated by credible evidence in existence at the time of disclosure; (iii) is independently developed by Licensee without use of or reference to the Confidential Information, as demonstrated by credible evidence in existence at the time of independent development; or (iv) is disclosed generally to third parties by Microchip without restrictions similar to those contained in this Agreement. Licensee may disclose Confidential Information to the extent required under law, rule, or regulation (including those of any national securities exchange), by subpoena, civil investigative demand, or similar process, or by a court or administrative agency (each a “Requirement”’), provided, that to the extent permitted by applicable law, Licensee will provide prompt notice of such Requirement to Microchip to enable Microchip to seek a protective order or otherwise prevent or restrict such disclosure. (b) Return of Materials. Upon Microchip’s request and direction, Licensee will promptly return or destroy the Confidential Information, including any physical information or materials provided to Licensee (together with any copies, excerpts, syntheses, CD ROMS, diskettes, etc.), and, in the case of information derived therefrom, provide written certification that all the Confidential Information has been expunged from any such materials or that all such materials have been destroyed. Further, if Licensee or its affiliates become competitors of Microchip, and Microchip notifies Licensee in writing of its status as a competitor in a given market, then Licensee will promptly engage in the return and certification process described above in this Section 5(b).
6. Ownership and Retention of Rights. All rights, title, and interest (including all intellectual property rights) in and to the Software, including any derivative works of the Software and any incremental modifications to the Software whether made by or for Licensee or Microchip (collectively, “Microchip Property”), are and will remain the sole and exclusive property of Microchip, whether such Microchip Property is separate or combined with any other products. Licensee, on behalf of itself and its affiliates, agrees to, and does hereby, assign to Microchip or its designee all right, title and interest (including all intellectual property rights) in and to derivative works of and any incremental modifications to the Software. Licensee will take (and will cause its affiliates, their subcontractors, and all related individuals to take) all action as may be reasonably necessary, proper or advisable to perfect and secure the ownership, licenses, intellectual property and other rights of or to Microchip as set forth in this Agreement. All rights not expressly granted under this Agreement are reserved to Microchip and its licensors and suppliers, and there are no implied rights. Licensee retains all right, title, and interest in and to any technology independently developed by Licensee not derived, directly or indirectly, from the Microchip Property or any other item of tangible property provided to Licensee by Microchip hereunder.
7. Termination. This Agreement will start once accepted by Licensee and continue unless and until terminated as provided in this Agreement. This Agreement automatically terminates immediately if Licensee violates the restrictions set forth in Sections 1, 2 or 4(a). Microchip may terminate this Agreement immediately upon notice if (a) Licensee or its affiliates become competitors of Microchip, or (b) Licensee breaches any other term of this Agreement and does not cure such breach within 30 days after receipt of written notice of such breach from Microchip. Upon termination of this Agreement, (i) the license grants in Sections 1 and 2(b) terminate, and (ii) Licensee will return to Microchip or destroy (and certify the destruction of) all Microchip Property and Confidential Information in its possession or under its control, and all copies thereof. The following sections survive termination of this Agreement: 3, 4, 5, 6, 7, 8, 9, 10 and 11.
8. EU Consumers – Applicable Terms. WHERE LICENSEE IS A CONSUMER LOCATED IN EUROPE, THE FOLLOWING PROVISIONS APPLY INSTEAD OF SECTIONS 9 AND 10 BELOW: Microchip and its licensors will not be liable (a) for any loss suffered by Licensee in connection with the Software where such loss was not reasonably foreseeable when the Software was first downloaded by Licensee, even if such loss was the result of negligence or the failure of Microchip and its licensors to comply with this Agreement; or (b) irrespective of the basis of claim, for any loss of revenue, profit or other business or economic loss suffered. Some Software is made available to Licensee free of charge, and Licensee may at any time download further copies without charge to replace the Software initially downloaded and others may require a fee to be downloaded, or to download any further copies. In all circumstances, to the extent liability may lawfully be limited or excluded, the cumulative liability of Microchip and its licensors will not exceed USD$1,000 (or equivalent sum in the currency of the country in which Licensee resides). However, none of the foregoing limits or excludes any liability for death or personal injury arising from negligence, or for fraud, fraudulent misrepresentation or any other cause that by law cannot be excluded and limited.
9. Warranty Disclaimers. EXCEPT FOR CONSUMERS TO WHOM SECTION 8 APPLIES, THE SOFTWARE IS LICENSED ON AN “AS-IS” BASIS. MICROCHIP MAKES NO WARRANTIES OF ANY KIND WITH RESPECT TO THE SOFTWARE, WHETHER EXPRESS, IMPLIED, STAUTORY OR OTHERWISE, AND EXPRESSLY DISCLAIMS ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE OR NON-INFRINGEMENT AND ANY WARRANTIES THAT MAY ARISE FROM USAGE OF TRADE OR COURSE OF DEALING. MICROCHIP AND ITS LICENSORS HAVE NO OBLIGATION TO CORRECT ANY DEFECTS IN THE SOFTWARE. TECHNICAL ASSISTANCE, IF PROVIDED, WILL NOT EXPAND THESE WARRANTIES. IF CUSTOMER IS A CONSUMER, THE ABOVE WILL NOT ACT TO EXCLUDE YOUR STATUTORY RIGHTS.
10. Limited Liability. EXCEPT FOR CONSUMERS TO WHOM SECTION 8 APPLIES, IN NO EVENT WILL MICROCHIP BE LIABLE, WHETHER IN CONTRACT, WARRANTY, REPRESENTATION, TORT, STRICT LIABILITY, INDEMNITY, CONTRIBUTION OR OTHERWISE, FOR ANY INDIRECT, SPECIAL, PUNITIVE, EXEMPLARY, INCIDENTAL OR CONSEQUENTIAL LOSS, DAMAGE, COST OR EXPENSE OF ANY KIND WHATSOEVER, HOWEVER CAUSED, OR ANY LOSS OF PRODUCTION, COST OF PROCUREMENT OF SUBSTITUTE PRODUCTS OR SERVICES, ANY LOSS OF PROFITS, LOSS OF BUSINESS, LOSS OF USE OR LOSS OF DATA, OR INTERRUPTION OF BUSINESS ARISING OUT OF THIS AGREEMENT, HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, EVEN IF MICROCHIP HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSS, AND NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED REMEDY. MICROCHIP’S TOTAL AGGREGATE LIABILITY UNDER THIS AGREEMENT WILL NOT EXCEED USD$1,000.
11. General. (a) This Agreement will be governed by and construed in accordance with the laws of the State of Arizona and the United States, without regard to conflicts of law provisions. The parties hereby irrevocably consent to the exclusive personal jurisdiction and venue of the state and federal courts in Maricopa County, Arizona for any dispute relating to this Agreement. WHERE LICENSEE IS A CONSUMER LOCATED IN EUROPE, this Agreement is subject to the laws of the country in which the Software is downloaded, and, to the extent so mandated by such laws, subject to the jurisdiction of the courts of that country. The parties expressly disclaim the applicability of the United Nations Convention on Contracts for the International Sale of Goods in connection with this Agreement. (b) Unless the parties have a mutually executed agreement relating to the licensing of this Software by Microchip to Licensee (“Signed Agreement”), this Agreement constitutes the entire agreement between the parties with respect to the Software and supersedes and replaces prior or contemporaneous written or verbal agreements or communications between the parties regarding the Software, including any purchase orders. If the parties have a Signed Agreement, this Agreement does not supersede or replace that Signed Agreement. This Agreement may not be modified by Licensee except by a written agreement signed by an authorized representative of Microchip. Microchip reserve the right to update this Agreement from time to time and to replace the existing Agreement without notice to Licensee. If any provision of this Agreement is held by a court of competent jurisdiction to be illegal, invalid, or unenforceable, that provision will be limited or eliminated to the minimum extent necessary so that this Agreement will otherwise remain in full force and effect and enforceable. No waiver of any breach of any provision of this Agreement constitutes a waiver of any prior, concurrent, or subsequent breach of the same or any other provisions of this Agreement, and no waiver will be effective unless made in writing and signed by an authorized representative of the waiving party. (c) Licensee agrees to comply with all import and export laws and restrictions and regulations of the Department of Commerce or other United States or foreign agency or authority. (d) This Agreement will bind and inure to the benefit of each party’s permitted successors and assigns. Licensee may not assign this Agreement in whole or in part, whether by law or otherwise, without Microchip’s prior written consent. Any merger, consolidation, amalgamation, reorganization, transfer of all or substantially all assets or other change in control or majority ownership (“Change of Control”) is considered an assignment for the purpose of this Section. Any attempt to assign this Agreement without such consent will be null and void. However, Microchip may assign this Agreement to an affiliate, or to another entity in the event of a Change of Control. (e) Licensee acknowledges its breach of any confidentiality or proprietary rights provision of this Agreement would cause Microchip irreparable damage, for which the award of damages would not be an adequate remedy. Licensee, therefore, agrees if Microchip alleges that Licensee has breached or violated any such provisions then Microchip may seek equitable relief, in addition to all other remedies at law or in equity. (f) Consistent with 48 C.F.R. §12.212 or 48 C.F.R. §227.7202-1 through 227.7202-4, as applicable, the Software is being licensed to U.S. Government end users (i) only as Commercial Items, and (ii) with only those rights as are granted to all other end users pursuant to the terms and conditions of the applicable Microchip licenses. To the extent the Software (or a portion thereof) qualifies as ‘technical data’ as such term is defined in 48 C.F.R. §252.227-7015(a)(5), then its use, duplication, or disclosure by the U.S. Government is subject to the restrictions set forth in subparagraphs (a) through (e) of the Rights in Technical Data clause at 48 C.F.R. §252.227-7015. Contractor/manufacturer is Microchip Technology Inc., 2355 W. Chandler Blvd., Chandler, AZ 85224-6199.
