Installation

Software
All APx systems use the same award-winning measurement software, APx500.
APx “B Series” analyzers
All analyzers shipped in late December 2018 (or afterward), including the APx517 acoustic audio analyzer, have a new embedded processor and enhanced security provisions. These analyzers are designated “B Series” and carry “B Series” nomenclature. “B Series” APx analyzers do not require an APx KeyBox (see below), but may require authorization codes to enable APx500 software or software options.
See Chapter 1 of the APx500 User’s Manual for information on the APx KeyBox and using current APx500 software with an earlier APx analyzer (non “B Series”).

PC system requirements
The APx500 measurement software requires a personal computer (PC) with the following features and capabilities:
· Operating system: Microsoft Windows 10 (64-bit).
· Intel i5 or better processor running at a clock speed of at least 2.5 GHz. AMD Processors with similar specifications are also supported.
· At least 8 GB of RAM. 16 GB is recommended.
· At least 1.5 GB of free hard disk space. An SSD for the operating system drive is highly recommended.
· A CD-ROM optical disc drive or Internet connection to download and install software.
· A USB 2.0 port or USB 3.0 port.

APx517 B Series Acoustic Audio Analyzer: Installation

· A color monitor with SXGA (1280 x 1024) video graphics support. Video resolution of 1900 x 1080 or greater is recommended.
System performance is sensitive to processor speed; faster processors will yield faster results.
APx500 is data intensive and it is recommended that other data-intensive applications not be run concurrently. This includes Audio Precision’s AP2700, APWIN or ATS.
Installation
To install the measurement software, insert the APx500 application disc into the optical drive on the PC and follow the instructions in the installation dialog. If you don’t have the APx500 application disc, you can download APx500 from the Audio Precision Web site at ap.com.
NOTE: You must have local administrator rights to install APx500 software. Go to User Accounts in the Windows Control Panel, or check with your network administrator.
Running the software without instrument hardware attached
NOTE: You must have standard user rights or administrator rights to operate APx500 software. Guest users are not supported.
You can launch the APx500 software without instrument hardware attached. When no hardware is detected, APx500 will present you with the following dialog box:
24

Select “Demo Mode.” APx500 will run in demo mode, which allows you to explore the user interface but does not enable any measurement functions.

Running the software with instrument hardware attached
NOTE: You must have standard user rights or administrator rights to operate APx500 software. Guest users are not supported.
Connecting the instrument to your PC Before connecting your APx517 instrument to your PC, install the APx500 measurement software as described above. Connecting the instrument prior to software instal-
APx517 B Series Acoustic Audio Analyzer: Installation

lation may cause Windows to select an incorrect USB driver for the instrument.
USB driver selection The measurement software communicates with the APx517 using a USB 2.0 interconnection. Once the software is successfully installed, connect one end of the USB cable to a USB 2.0 port on the PC, and the other end to the PC INTERFACE port on the rear of the APx517. We strongly recommend that you use the USB cable included with your instrument (AP part number CABAPSI). We have tested other USB cables that perform poorly.
Note: Some PCs have optional USB ports on the front of the PC, or on extension brackets on the rear. In many cases these convenience ports have compromised performance due to the extra cable length within the PC. We recommend using USB ports directly connected to the PC motherboard, typically at the rear of the PC.
Connect the APx517 mains power cord to the instrument and to a source of ac mains power. See the Mains Power and Fusing section that follows for more information about mains connections.
Turn the instrument on by rocking the mains power switch to ON ( | ). The mains power switch is located in the power entry module on the rear of the APx517. Windows will detect the presence of the APx517 on the USB port and will open the Hardware Update Wizard to search for the correct software driver. Select “Install the soft-
APx517 B Series Acoustic Audio Analyzer: Installation

ware automatically.” Windows will find the Audio Precision driver software installed with APx500 and connect to the APx517.
Launch APx500 by double-clicking on the installed shortcut. With the APx517 connected, you may be asked to update the instrument firmware during the first launch of the measurement software. APx500 will start, and in a short time you will be presented with the opening screen. Refer to the APx500 User’s Manual for more information about making measurements.
The APx500 User’s Manual is available as a PDF on the APx500 Application Disc and online at ap.com; a hard-copy version can be ordered from Audio Precision or your local distributor.
Mains Power and Fusing
Connect the APx517 mains power cord to the instrument and to a source of ac mains power. Turn the APx517 on by rocking the mains power switch to ON ( | ). The mains power switch is located in the power entry module on the rear of the analyzer.
Connecting your instrument to the electrical mains supply
A n APx517 must be connected to a 5060 Hz alternating current (ac) electrical mains supply. The minimum voltage is 100 Vac; maximum voltage is 240 Vac. Use only adequately rated detachable mains power cords.
25

The analyzer is fitted with a universal power supply that does not require voltage configuration or change of fuse type to accept mains voltages within the specified range.
Removing and installing mains fuses
For all rated voltages, use two mains fuses of type
· 4 A T/SB (5×20 mm) 250 V.
Use only certified fuses of the appropriate specifications.
To remove the mains fuse carrier module, refer to the figures below and proceed as follows:

Remove the mains power supply cord from the connector on the power entry module, located on the APx517 rear panel. The mains fuse carrier module is part of the power entry module, below the power switch.
Insert a small screwdriver into the slot at the bottom of the power entry module as shown in figure 1, and pry open the hinged door to reveal the red mains fuse carrier module. Lift the fuse carrier module with the screwdriver as shown in Figure 2, and then pull it out of the power entry module using your fingers. The two mains fuses are loosely mounted within the fuse carrier module; take care not to let them fall.

Replace the fuses if necessary, using fuses as described above. Note that the fuses mount between the center contact clip and the contact nearest the module pins, as shown in figure 3 and 4. Carefully reinsert the fuse carrier module into the power entry module, and press it firmly into place. Firmly close the hinged door.

APx517 B Series Acoustic Audio Analyzer: Installation

Connect the power cord from a mains power outlet to the power cord connector on the APx517 rear panel.
Modular Headphone Connector Panels
The APx517 has field-swappable modular headphone output connector panels that fit in the headphone amplifier output bay. The panels are available with one of three connector types:
· 1/4 inch jack
· 3.5 mm jack
· Dual BNC
If changes in testing requirements require a different headphone connector, the headphone panel can be replaced. Additionally, as headphone connectors wear out from the repeated plugging and unplugging of cables during production test, they can be replaced.
Removing a Modular Headphone Connector Panel
To remove the headphone connector panel from the APx517 chassis:
1. Loosen the two thumbscrews to release the connector panel from the APx517 chassis. (See Figure 5)
2. Holding the thumbscrews, pull the panel straight out from the APx517 chassis. The panel slides on a slotted rail on each side of the panel opening in the chassis.

Figure 5
Installing a Modular Headphone Connector Panel
To install the headphone connector panel in the APx517 chassis:
1. Carefully remove the headphone connector panel from the protective packaging.
2. Holding the connector panel by the panel face or by the thumbscrews, align the sides of the panel with the panel rail slots on each side of the panel bay and insert the connector panel straight into the chassis. (See Figure 5)

APx517 B Series Acoustic Audio Analyzer: Installation

If the connector panel does not slide in smoothly, check to ensure that the panel is inserted straight in the chassis and that the left and right edges are sliding in the panel rail slots in the panel bay.
3. Slide the panel completely into the APx517 chassis so that the panel face is flush with the chassis front panel.
4. Tighten the thumbscrews so that they hold the panel securely against the chassis.
If the thumbscrews are not secure, unplugging a headphone connector can loosen the panel connection and cause inconsistent measurement results.

NP0020.00036 rev 002 March, 2020

This illustration shows the PDM module, model 236.
The PDM option provides a complete solution for addressing circuits or devices with a PDM input or output. The PDM signal output consists of an APx generator audio signal, interpolated by a broad choice of oversampling ratios, and modulated into a 1-bit PDM bitstream. A 4th-order modulator is the default; a 5th-order modulator can be selected. The PDM Option also provides a signal input with its associated clock connection. The input accepts a 1bit PDM bitstream, which is then decimated by one of a wide range of decimation ratios and filtered into baseband audio at the Decimated Rate. The input bitstream can also be analyzed directly (before decimation) in the Signal Analyzer to view out-of-band components.
These specifications cover the digital input and output functions of the Audio Precision PDM interface for the current version, model 236.

with APx500 v5.0.3 or higher measurement software as fitted in APx516, 517, 52x, 555 and 58x B Series audio analyzers
NP0020.00046 rev 000 November 2019

This illustration shows the PDM 16 module, model 243, and PDM 16 remote interface pod.
The PDM 16 option provides a solution for addressing circuits or devices with multiple PDM outputs. The PDM 16 option provides up to 16 acquisition channels that connect through the module’s PDM 16 remote interface pod. All 16 channels can be measured simultaneously to provide sample-accurate interchannel information. The input accepts 1-bit PDM bitstreams, which are then decimated by one of several available decimation ratios and filtered into baseband audio at the Decimated Rate. The PDM 16 also provides a variable Vdd supply (0.0 V-3.6 V, 50 mA max.) and a bit clock that can be configured as an input or an output.
The PDM 16 remote interface pod provides a 40-pin, 0.1″ (2.54mm) pitch IDC connector as an interface to PDM MEMS microphones. All signal pins are provided with individual, shared grounds. All clock outputs are redundant but individually buffered to drive multiple clock inputs if required. The Vdd output provides DC power, if required, for the device under test. The 8 data input pins can be used to interface up to 16 microphones simultaneously. The input is compatible with commonly available IDE / parallel ATA I/O cables.
