Maximum Leveled Power Check Failure; Checking The Output Power - Keysight E8257D Installation Manual

Maximum Leveled Power Check Failure

If a maximum leveled power check fails, perform the following procedure:
1. Verify the limits for that particular option using the data sheet.
2. If the Unlocked annunciator is displayed, refer to the Troubleshooting chapter of the E8257D/67D
and E8663D PSG Signal Generators Service Guide.
3. Ensure that the RF OUTPUT connector is connected to a 50Ω load.
4. Ensure that the power level entered corresponds to the value listed in
Table 3-3.
Table 3-4,
5. Refer to
output power.
If the measured power level is more than the power level listed in
Table 3-3, turn the front panel knob counterclockwise until the measured power level equals the
Table
power level in
6. Note the signal generator front- panel amplitude value and use it to repeat the maximum leveled
power check.
If you have followed the above steps and the check continues to fail, contact the nearest Keysight
Technologies call center for assistance. Refer to
page 11
for contact information.
