VERSION 1.7.14J RELEASE

OVERVIEW
Version 1.7.14j provides a fix and an enhancement.
CRITICAL FIX

Symptom:
Resolution:| SK-2330

The instrument will become unresponsive if a LAN cable is disconnected and reconnected nine times or more.
A power cycle is required to make the instrument responsive.

**** This issue has been resolved.

---|---

ENHANCEMENT

• New commands have been added to control the connection rule for closing and opening channels in the instrument:
• TSP: channel.connectrule (default channel.CONCURRENT) SCPI: :ROUTe[:CHANnel]:CONNect:RULE (default CONCurrent)
• The connection rule describes the order in which switch channels are opened and closed during channel operations. This applies to scanning operation and when using these commands when a channel is set to a function.
• The default value does not guarantee a connection rule. The instrument closes relays as efficiently as possible to improve speed performance without applying a rule.
• When the connection rule is set to break before make, the instrument ensures that all switch channels open before any switch channels close.
• When the connection rule is set to make before break, the instrument ensures that all switch channels close before any switch channels open.

For additional information on these commands, refer to the Model DAQ6510 Data Acquisition and Multimeter System Reference Manual (document number DAQ6510-901-01). This manual is available online at tek.com/keithley.

Reference number: Symptom:

**Resolution:**

| NS-2105

Running a scan with the automatic scan restart feature enabled and restarting the trigger model periodically may lead to an out of memory error message, depending on how often the trigger is reinitialized.

The error may also occur when saving numerous configuration scripts or system setups, depending on the time since the instrument has been restarted.

**** This issue has been resolved.

NOTE

If you are upgrading from a firmware version earlier than 1.7.10, use the Downgrade to older option from the front panel or use the downgrade remote commands. See “Upgrading the firmware” in your instrument’s Reference Manual for more information. When upgrading from a firmware version earlier than 1.7.10, system messages will display the firmware version as 1.7.1. This is a cosmetic issue and does not affect instrument performance.
If you are upgrading your instrument from version 1.7.10, follow the “Installation Instructions” in the General Information section of this document.

Reference number: Symptom:

**Resolution:**

| NS-1962

When scanning with four-wire measurements on a channel followed by two-wire measurements on a subsequent channel with a 7706 or 7707 card installed, the first scan results in correct measurements for the four- wire channel, but incorrect four-wire channel readings for subsequent scans.

This error is caused by an upper-bank channel closing improperly when stepping from one channel to another, interfering with the readings for the second scan loop and any subsequent loops.

**** This issue has been resolved.

---|---
Reference number: Symptom:

**Resolution:**

| NS-2077

When writing a large amount of reading buffer data to a USB drive, a newline character (\n) may be missed and result in two data rows being written as one row.

**** This issue has been resolved.

NOTE

When you load the 1.7.10 firmware into your instrument, system messages will display the firmware version as 1.7.1. This is only a cosmetic issue and does not impact the performance of the unit. Subsequent firmware upgrades will display a two-digit firmware version number.
To install firmware version 1.7.10 on your instrument, use the Downgrade to older option from the front panel or use the downgrade remote commands. See “Upgrading the firmware” in your instrument’s Reference Manual for more information.

Version 1.7.10 provides fixes and enhancements.

CRITICAL FIXES

attempts without a USB flash drive inserted into the front port of the instrument may cause the instrument to become unresponsive.
Resolution:| This issue has been resolved.
Reference number:| NS-2070
Symptom:| Heavy script processing can interfere with the timely generation of an SRQ as the result of setting the MAV bit in the Status Byte Register. This interference affects both the bus and the front panel display.
Resolution:| This issue has been resolved.
Reference number:| NS-2072
Symptom:| After changing the group number of a node to be the group number previously used for another node, the instrument may generate errors when trying to start a test on that node using the execute() command, even after using waitcomplete() to make sure the previous tests have finished. Subsequently, performing a waitcomplete() on the previous group number may cause the instrument to wait for tests to complete on that node even though the node is in a new group.
Resolution:| This issue has been resolved.
Reference number: Symptom:

Resolution:

| NS-2074

The MAV bit may be set in the status byte indicating that there is data to be read from the instrument, but the subsequent read operation to pull that data from the instrument fails and times-out. This may occur when rapidly generating data and enabling the MAV bit to be set in the status model to indicate when data is available to read from the instrument.

**** This issue has been resolved.

---|---

ENHANCEMENTS

• NS-1946
• New commands have been added:
• TSP: lan.dstprotection = lan.ON or lan.OFF
• SCPI: SYSTem:COMMunication:LAN:DST:PROTection <ON (1) or
• OFF(0)>
• OFF is the default command state.
• When DST protection is turned OFF, a simple open-and-close on the DST port (5030) will close any and all open LAN connections.
• When DST protection is turned ON, the DST port will need to be opened and the system login and password entered followed by closing the DST port to close any open LAN connections, including the DST port.
• Turning DST protection ON prevents LAN connections from being inadvertently closed by your IT department performing a port scan across the corporate network.

VERSION 1.7.8 RELEASE
OVERVIEW
Version 1.7.8 provides fixes.

CRITICAL FIXES

Reference number: Symptom:

**Resolution**

| NS-1964

After configuring a scan in SCPI 2700 or SCPI 2701 emulation mode, the READ? command closes the first channel and takes a reading, then advances to the second channel in the scan list. Subsequent READ? commands do not advance the scan to the next channel in the list. The subsequent READ? commands respond with a reading being measured on the second channel in the scan sequence and not on the expected channel.

**** This issue has been resolved.

---|---
Reference number:| NS-1972
---|---
Symptom:| After configuring a scan in SCPI 2000 emulation mode, the TRACe:DATA? command is used to trigger and scan through the channels in the scan list. The front panel indicates that the first channel closes, but the instrument does not audibly indicate closure and opening of the remaining channels in the scan list. No data is returned in response to the TRACe:DATA? command.
Resolution:| This issue has been resolved.
Reference number:| NS-2004
Symptom:| In SCPI 27xx emulation mode, non-measurement channels (such as those on a 7705 card) closed with the ROUTe:MULTi:CLOSe command prior to starting a scan do not remain closed during the scan as expected, as they are errantly opened when the scan is initiated.
Resolution:| This issue has been resolved.
Reference number: Symptom:

Resolution:

| NS-1933

In SCPI 2701 emulation mode, a user cannot send a channel list parameter that worked for a Model 2701. The -154, string too long error is generated.

After running a scan and then disabling a channel group from the scan on the front panel, running the scan again returns Error -285 TSP: “Syntax error at a line due to an unfinished string.”

The issue has been resolved.

Reference number: Symptom:

**Resolution:**

| NS-2017

When appending buffer data to a .csv file using the buffer.saveappend command, the line with channel numbers is shifted over to start with the time column instead of starting with channel data columns, as the line for channel labels does.

**** This issue has been resolved.

blocks on the Trigger Flow screen on the front panel now allows a minimum value of 0.
Reference number: Symptom:

**Resolution:**

| NS-1908

Changing an annunciator setting (such as auto zero or filter enable) on the Settings or Calculations screen is not reflected in the Home screen annunciators.

Symptom:| The LXI identification web page shows the incorrect LXI version and web
| page links.
Resolution:| This issue has been corrected.
Category| Remote commands
---|---
Reference number:|

• NS-1931: Added a TLS (transport layer security) option when using the
• tspnet.connect() command.
• connectionID = tspnet.connect(ipAddress, portNumber, initString, useTLS)
• ipAddress : A string that indicates the IP address or host name to connect to.
• portNumber : Default 5025.
• initString : Sends a string to ipAddress. useTLS : 0 or 1;
• 0: Do not use TLS with the connection (default)
• 1: Use TLS with the connection.

When useTLS is set to 1, the instrument negotiates the security protocol when connecting to the host or IP address that is used. This security protocol is used when using tspnet.write() to send data or tspnet.read() to receive data.

The following is an example of how to use a host name with the TLS option:

connectionID = tspnet.connect(“ hostname.domain.com ”, 443, “”, 1)

Category| Remote commands
Reference number:| NS-1960: The localnode. gettimewithfractional() TSP command is available to retrieve the number of seconds elapsed since January 1, 1970, with fractional seconds appended to the returned response.

NONCRITICAL FIXES

Reference number Symptom:

**Resolution:**

| 5 N 5T IHK-6331

• 5 U 5T sing the Keithley Model 7701, 7706, or 7708 to make measurements may result in overflows and inaccuracies when, without opening all of the channels in between, you make a 2-wire measurement followed by a 4-wire measurement or a 4-wire measurement followed by a 2-wire measurement. A scan with both 2-wire and 4-wire measurements may be inaccurate after the change in function has occurred.
• 5 A 5T __ scan with a single function, either 2-wire or 4-wire measurements, would contain accurate measurements. The USB interface may exhibit lockups when used for extended periods.
• 5 T 5T he 7701, 7706, or 7708 now make accurate measurements for all combinations of 2-wire and 4-wire measurements, whether in a scan, script, or from the display.

Resolution:| The USB interface has been changed to improve performance, status byte responsiveness, and long-term reliability. There is no impact to VISA compatibility.
Reference number:| NIHK-6176
Symptom:| Using the infinite count in a trigger model can yield unexpected results.
Resolution:| The use of an infinite count in a trigger model has been improved and functions as expected.
Reference number:| NIHK-6183, NIHK-6204, NIHK-6211
Symptom:| When the KTTI-GPIB card is installed and GPIB communications are used, the SRQ line on the GPIB interface is not functional
Resolution:| The SRQ line is now properly driven on the GPIB interface.
Reference number:| NIHK-6184
Symptom:| Frequent switching using the FRONT/REAR TERMINALS switch may make the instrument inoperable.
Resolution:| The switching between front and rear terminals has been improved.
Reference number:| NIHK-6242
---|---
Symptom:| When the instrument is emulating the Keithley Model 2700 the instrument uses a different version of the moving average filter than the actual Keithley Model 2700 or 2701.
Resolution:|

• Emulation of the Keithley Model 2700 and 2701 now uses the same version of the moving average filter as the original products. This type of filter is also available in non-emulation modes under the name Hybrid Average filter. Channels do not support the hybrid filter type.
• A hybrid filter combines characteristics of the repeating and moving filter types. A hybrid filter always averages an entire window of readings before returning the requested filtered reading. If the window is empty when the first reading is triggered, multiple readings are made to fill the window, after which the single requested filtered reading is returned. This process may take longer than a single reading. Once the window is filled, subsequent triggers make a single reading, add it to the window, and return the single requested filtered reading. This process will take the duration of a single reading.
• The TSP and SCPI commands for these filter-type options are
• 4 d 2T mm.measure.filter.type  dmm.FILTER_HYBRID_AVG and
• [SENSe[1]]::AVERage:TCONtrol:  HYBRid.

Reference number:| 5 N 5T IHK-3957
Enhancement:| 5 W 5T __ hen the EXIT key is pressed, the previous screen becomes active. Previously, the instrument returned to the menu screen.
Reference number:| 5 N 5T IHK-5778
Resolution:| 5 T 5T he scan time for scans with a count greater than one and autoranged functions has been improved. The instrument now retains the range learned from the first scan iteration and uses it as a basis for delays and ranging on subsequent scans. Previously, only worse case values were considered.
Reference number:| 5 N 5T IHK-6156
Resolution:| 5 S 5T CPI commands were added to programmatically control the display’s active reading buffer and watch list. Additional documentation can be found in the latest reference manual under the 4 : 2T55T DISPlay:WATch:CHANnels 42 T a 55T nd

4 : 2T55T DISPlay:BUFFer:ACTive 42 T c 55T ommands.

Reference Number| 5 N 5T IHK-6158
Enhancement| 5 T 5T he Reset Popups button on the Event Log screen and Log Settings tab now clears the error log of any suppressed warning popups. When a warning event occurs, the user interface displays a popup. You can suppress the popup so that subsequent warnings do not generate a popup. Previously, the suppression list could not be cleared.
Reference number:| 5 N 5T IHK-6168
---|---
Enhancement:| 5 S 5T CPI now allows the use of the dBm unit in a writable buffer. Additional documentation can be found in the latest reference manual under the

4 : 2T55T TRACE:WRITE:FORMAT 42T c 55T ommand.

Reference number:| 5 N 5T IHK-6171, NIHK-6172
Enhancement:| 5 A 5T __ moving average filter is no longer allowed as a filter type on a channel. The moving average filter makes a reading, averages it with a previous set of readings, and returns the result. This can yield unexpected results during a scan because the averaged readings will not be sequential in time. To prevent inadvertent errors, this option has been removed for channels. It is still available for normal DMM usage.
Reference number:| 5 N 5T IHK-6195
Enhancement:| 5 T 5T he time taken to switch functions using the front panel has been reduced substantially across all function.
Reference number:| 5 N 5T IHK-6213
Enhancement:| 5 A 5T ll emulation modes now support a beeper for continuity and limits.
Reference number:| 5 N 5T IHK-6221, NIHK–6236
Enhancement:| 5 T 5T he scan screen menu has been changed as follows. The command Create New has been renamed to Create New List. Save has been renamed to Save System. The functionality is the same. There are two additional menu entries. The first is Reset Scan Settings, which clears the scan list and resets all settings associated with a scan, but not DMM settings. The other is Reset System, which redirects you to System Info and Management where the Reset button, which resets the entire instrument to power-on defaults, is located.
Reference number:| 5 N 5T IHK-6258
Enhancement:| 5 T 5T CP/IP communication speeds have been improved for short packets.
Reference number:| 5 N 5T IHK-6277
Enhancement:| 5 A 5T ll emulation modes now support a beeper for continuity and limits.
Reference number:| 5 N 5T IHK-6303
Enhancement:| I 55 T n 2701 emulation mode, the following command is now supported as described in the Model 2701 User’s Manual : 4 T 2T55T RACe:POINts:ACTual 4. 2 T. 55 T.
Reference number:| 5 N 5T IHK-6329
Enhancement:| 5 W 5T hen opening and appending a file on a USB flash drive, if the file does not exist it will be created. If the file exists, it will be appended to as before. This affects the 4 f 2T55T ile.open() 42 T a 55T nd 4 i 2T55T o.open() 42 T T 55T SP commands.
