SOURce[1]:AMPLitude
Set
Query
Description Sets the output amplitude for the
SOURce[1]:FUNCtion command. The query
command returns the current amplitude settings.
Note
The maximum and minimum amplitude depends
on the output termination. The default amplitude
for all functions is 100 mVpp (50Ω).
The offset and amplitude are related by the
following equation.
|Voffset| < Vmax – Vpp/2
The output amplitude can be affected by the
function and unit chosen. Vpp and Vrms or dBm
values may have different maximum values due to
differences such as crest factor. For example, a
5Vrms square wave will be adjusted to 3.536 Vrms
for a sine wave.
The amplitude units can be explicitly used each
time the SOURce[1]:AMPLitude command is used.
Alternatively, the VOLT:UNIT command can be
used to set the amplitude units for all commands.
Syntax SOURce[1]:AMPLitude {< amplitude>
|MINimum|MAXimum}
Example SOUR1:AMPL MAX
Sets the amplitude to the maximum for the current
mode.
Query Syntax SOURce[1]:AMPLitude? {MINimum|MAXimum}
Return Parameter <NR3> Returns the amplitude for the current
mode.
