How to Set the Amplitude Output (with the EMF Mode Off)
You can set the amplitude output by selecting the amplitude function and then setting
the desired output level:
I AMpTD I
and the desired output level (in dBm, V, mY, uV, or dBuV; the
I RAD %
J
key
is the dBuV terminator).
Example
Set the RF output to -107.3 dBm.

AMPTO REl
Amplitude has been set to 6.0 dBuV. The AMPTD REL annunciators indicate that dBuV
is a relative setting. Even though dBuV can be set directly from the front panel, the way
this function operates and the way it is displayed are similar to most relative settings.
(Refer to Relative Amplitude, page 3-77.)
