Software Problems

Baseband Generator DAC over range

After downloading the waveform, the ESG displays error: Baseband Generator DAC over range.

Cause: The number of frames and some baseband filter selections (such as NONE) can result in a high crest factor, causing digital to analog converter (DAC) overflow.

Solution: Reduce the runtime scaling value. For example, 50 percent or less.

ESG Front panel keys do not work

After downloading the waveform, the ESG front panel keys do not work.

Cause: Downloading the waveform places the ESG in remote operation, which deactivates the front panel operation.

Solution: On the ESG, press the Local key to restore front panel operation.

ESG does not play the waveform

After clicking Download in the tool bar, the ESG does not play the waveform.

Cause: The configured bursts may exceed the length of the defined frame or the size of the generated waveform may exceed the Arb memory.

Solution: Click Check Parameters in the tool bar to verify that the configured bursts do not exceed the length of the defined frame. A parameter status window appears displaying OK if the configuration is valid. If there is invalid parameter usage, the parameter status window displays a red error symbol, parameter name, conflict description, and corrective action suggestions needed to modify the frame parameters. All conflicts must be resolved before the waveform can be generated.

In some configurations, the generated waveform size exceeds 8 Msamples. In this case, it isn't possible to transfer the waveform into the ESG with Options 001 or 601. Use an ESG with Options 002 or 602 for more waveform memory. (You can check your waveform size under Data Points in the Project Property. window.) 

An Authorization dialog box or license error message appears

After clicking Download in the tool bar, or either Test Connection or Test All Connections in the Instruments window, an Authorization dialog box or license error message appears.

Cause: A license file for a signal generator being used cannot be found on the PC or in the instrument.

Solution: The software requires a license to be fully functional. You must have either a permanent license or a non-expired 14-day trial license for each signal generator being used. Make sure that any permanent license file is in the directory: C:\Program Files\Keysight\Signal Generation License Files\Drop on your computer. To get a free one time 14-day trial license or purchase a permanent license, see Licensing.

"FW version is not valid"

After clicking Test Connection or Test All Connections, "FW version is not valid" appears in the Note column of the Instruments window.

Cause: The current firmware version of the signal generator needs to be upgraded.

Solution: See system requirements for information on updating the required firmware.

"Connection failed"

After clicking Test Connection or Test All Connections, "Connection failed" appears in the Note column of the Instruments window.

Cause: The instrument connection via LAN or GPIB may not be properly enabled.

Solution: Verify that all equipment is properly connected and that any LAN or GPIB interface has been correctly installed and configured. (See Keysight IO Libraries.) Ensure that the GPIB or LAN information that you entered in the Instrument window matches the instrument and interface you are using.
