Output Amplitude
When setting the amplitude, MINimum, MAXimum and
DEFault can be used. The range depends on the function
b
eing used and the output termination (50Ω or high
impedance). The default amplitude for all functions is 100
mVpp (50Ω).
If the amplitude has been set and the output termination is
changed from 50Ω to high impedance, the amplitude will
double. Changing the output termination from high impedance
to 50Ω will half the amplitude.
Vrms, dBm or Vpp units can be used to specify the output unit
to use with the current command. The VOLT:UNIT command
can be used to set the units when no unit is specified with the
Apply command. If the output termination is set to high
impedance, dBm units cannot be used. The units will default
to Vpp.
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 must be adjusted to 3.536
Vrms for a sine wave.
DC Offset voltage The offset parameter can be set to MINimum, MAXimum or
DEFault. The default offset is 0 volts. The offset is limited by
the output amplitude as shown below.

max
– Vpp/2
If the output specified is out of range, the maximum offset will
be set.
The offset is also determined by the output termination (50Ω
or high impedance). If the offset has been set and the output
termination has changed from 50Ω to high impedance, the
offset will double. Changing the output termination from high
impedance to 50Ω will half the offset.
