Self Test

Run Self Test for All Channels

Selecting All Channels from the Run Self Test listbox followed by Run displays diagnostic information for the instrument based on channels.

For information on running the self test using SCPI, see *TST? - Self Test Query

GUI Location

System Menu (triple bar icon) > Settings (gear icon) > Service > Self Test > Run Self Test > All Channels

Running Self Test takes at least five minutes to complete.

Run Self Test Per Channel

Query only

Performs the internal self-test routines for a specified RF Channel and returns a number indicating the success of the testing. A zero is returned if the test is successful, 1 if it fails.

GUI Location	System Menu (triple bar icon) > Settings (gear icon) > Service > Self Test > Run Self Test > Channel <n>
SCPI Command	:SYSTem:RF<channel>:STESt?
SCPI Example	SYST:RF3:STESt? !Runs the self-test routines for RF Channel 3 and returns 0=passed, 1=some part failed.
Notes	SYSTem:RF<channel>:STESt? May take many minutes to complete, set timeout value on controlling test program to a very large value (e.g. 10 minutes). Successful completion of self-test on the channel will clear the applicable bit in the STATus:QUEStionable:STFailed or STATus:QUEStionable:STFailed:ESTFailed register. Unsuccessful completion of self-test on the channel will set the applicable bit in the STATus:QUEStionable:STFailed or STATus:QUEStionable:STFailed:ESTFailed register.

Run Specific Self Test

Performs the internal self-test routines for a specified test on a specified RF channel and returns a number indicating the success of the testing. 0 is returned if the test is successful, 1 if it fails.

Use the GUI to specify the following:

Generate Report

GUI option only

The Generate Report button generates the .zip archive report containing a variety of system information and configuration files, including:

Log files
State files
Installed license files
Software and Hardware version information

These reports are intended for Keysight Support Engineers to assist in the diagnosis of undesirable instrument behaviors.

After the report is generated, you can copy the .zip archive report off the instrument.

If viewing the instrument interface from the instrument’s front panel, a QR code appears to copy the archive file to a QR-scanning device.
If accessing the instrument interface from the browser of a remote PC, the Download button appears to copy the file directly to the remote PC.

If a USB drive is attached, options appear to copy the archive file directly to the USB drive.

GUI Location

System Menu (triple bar icon) > Settings (gear icon) > Service > Utilities

Update Firmware

GUI option only

You can use one of the following methods for selecting a .ctp file to update the firmware. The availability of these methods depend on how you are accessing the instrument.

Method	Description
From this PC	Allows uploading the firmware from the remote PC to the instrument via your browser. This method is available only when accessing the instrument from the browser of a remote PC.
From USB	Detects attached USB drives, searching the root of the drives for files with a .ctp extension.
From Instrument	Select a file that has already been uploaded to the instrument storage.

Applying the new .ctp file requires a reboot. After selecting the file, the instrument will be rebooted automatically.

Logging

Log files are intended for Keysight Support Engineers to assist in diagnosis of undesirable instrument behaviors.

Understanding logging configuration and interpreting log files is expected of Keysight Support Engineers only.

The Logging Configuration options allows for precise modifications to the log output. These modifications can be done utilizing logging presets or manually by adding and removing individual loggers via the Add Logger button.

Add Logger

GUI option only

This drop-down adds a specific logger to the logging configuration.

Once added, loggers can be removed individually via the Minus button in the table.

Modifying the verbosity of any specific logger, added by preset or otherwise, can be done at anytime with the provided drop-downs. Verbosity options from high to low are:

Trace
Debug
Info
Warn
Error
Critical

Instrument performance may be affected if highly verbose logging is enabled.

GUI Location

System Menu (triple bar icon) > Settings (gear icon) > Service > Logging > Add Logger

Save

GUI option only

Save must be pressed before leaving the tab or all modifications will be lost. If the table is empty when Save is pressed, default logging behaviors will be restored.

GUI Location

System Menu (triple bar icon) > Settings (gear icon) > Service > Logging > Save

Logging Presets

GUI option only

Adds preconfigured loggers to the logging configuration.

The simplest way to configure logging is to use one of the available presets via the Logging Presets drop-down. These presets are preconfigured to aid in diagnosis of specific categories of instrument behaviors, adding a subset of loggers at specific verbosity levels.

GUI Location

System Menu (triple bar icon) > Settings (gear icon) > Service > Logging > Logging Presets

Write Log Flag

GUI option only

Immediately adds a line to the log for future reference. The text of the line will be:

"[siggen.custom] [info] Log Flag"

GUI Location

System Menu (triple bar icon) > Settings (gear icon) > Service > Logging > Write Log Flag

View Logs

GUI option only

Opens a log viewer for the most recent lines written to the log. This reads logs directly from file. Therefore, if a log file is manually deleted, this view will also be impacted. Options are available to change the number of lines displayed.

GUI Location

System Menu (triple bar icon) > Settings (gear icon) > Service > Logging > View Logs

Support Options/Recovery Menu

If the instrument application stops running for any reason, a dialog appears with a link to show the Support Options menu. This menu provides options for support and recovery. The tools available in this menu are:

Generate Report
Update Firmware
Logging

When configuring Logging, no Write Log Flag option is available.

When updating firmware, firmware files cannot be selected from arbitrary locations on the instrument. USB is the primary and supported method for providing firmware files.
