Software Problems

Baseband Generator DAC over range

After downloading the waveform, the signal generator 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.

Signal generator front panel keys do not work

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

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

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

"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.

"Restricted User" cannot run Signal Studio application

Cause: When a "Restricted User" tries to run the Signal Studio application without the correct security permissions, an unhandled exception error message indicates that access is denied.

Solution: The administrator must set the correct user permissions in the Signal Studio installation folder. See the instructions in User Permissions.
