Generator smf 100a writes error output unleveled. Gain control on upper limit.

0
1 comments:
Mr. Anderson
May 15, 2025

The error message "output unleveled" on the Rohde & Schwarz SMF100A generator indicates that the generator cannot maintain the set RF output level accurately.

To resolve the gain control issue:

1. Check if "User Correction" is active. If active, the output level is the sum of "Level" + "UCOR". Adjust or deactivate user correction if needed.
2. Verify if an "Offset" is set. The display shows "Level" - "Offset". Make sure the settings are correct.
3. If using "RF during Power Search" set to "Minimum", the generator uses a mechanical attenuator, which takes time. Ensure proper configuration or wait for it to stabilize.
4. Use the "Automatic Level Control" (ALC) settings to manage level stability.

Access these settings through:
Level Control > Configure > Automatic Level Control
or
Level Control > Configure > User Correction.
