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.
