Rf Output Power Too Low - Agilent Technologies E8241A User Manual

RF Output Power too Low

1. Look for an OFFS or REF indicator in the AMPLITUDE area of the display.
OFFS tells you that an amplitude offset has been set. An amplitude offset changes the value
shown in the AMPLITUDE area of the display but does not affect the output power. The
amplitude displayed is equal to the current power output by the signal generator
hardware plus the value for the offset.
To eliminate the offset, do the following:
Press >
Amplitude
REF tells you that the amplitude reference mode is activated. When this mode is on, the
displayed amplitude value is not the output power level. Rather, it is the current power
output by the signal generator hardware minus the reference value set by the
softkey.
To exit the reference mode, follow these steps:
a. Press
Amplitude
b. Press
Ampl Ref Off On
You can then reset the output power to the desired level.
2. If you are using the signal generator with an external mixer, see
While Working with Mixers" on page
3. If you are using the signal generator with a spectrum analyzer, see
