Signal Studio for WiMAX E4438C Option H13

Troubleshooting

CAUTION

Do not use “Save As” when saving the hosts file; this file does not have a file

extension.

Software Problems

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 on the “Project View” on page 22.

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

Cause: Downloading the waveform places the ESG in remote operation mode, which

deactivates front panel operation.

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