2 Features and Functions
Limits Due to Units Selection
In some cases, the amplitude limits are determined by the output units selected.
This may occur when the units are Vrms or dBm due to the differences in crest
factor for the various output functions.
For example, if you output a 2.5 Vrms Square wave (into 50 ) and then change to
the Sine wave function, the U2761A will automatically adjusts the output
amplitude to 1.768 Vrms (the upper limit for Sine wave in Vrms).
You can set the output amplitude in Vpp, Vrms, or dBm. For more information, see
"Output Units"
You cannot specify the output amplitude in dBm if the output termination is set to
"high impedance".
Soft Front Panel Operation
On the Amplitude panel as shown in
and select the unit from the drop down list.

Remote Interface Operation
Or, you can set the amplitude by specifying a high level and low level using the
following commands.
You can also use the APPLy command to select the function, frequency,
amplitude, and offset.
