[SOURce:]OUTPut:ANALog<CH>:AMODe ELECtronic | ATTenuators
The command sets the amplitude mode. Two of them are possible, Electronic or Attenuators. They
determine how precise the signals will be adjusted.
Using the Electronic mode, the instrument generates signal amplitudes by scaling the waveforms.
The adjustment can be performed very fast. The level resolution is low if a small signal amplitude
(<< 1V) is selected.
Using the Attenuators mode, the instrument generates signal amplitudes by applying a gauge
circuit to the waveforms. The instrument switches a relay. The adjustment takes some time. The
level resolution is high, especially for small signal amplitudes (<< 1V).

ELECtronic
[SOURce:]OUTPut:ANALog<CH>:BALanced:AMPLitude 0 ... 1.5 V
The command sets the maximum output voltage for the balanced signal. Small differences at the
inputs can be taken into account via the impairment settings offset and bias.
Example: OUTP:ANAL:BAL:AMPL 1.234V
*RST value
1 V
[SOURce:]OUTPut:ANALog<CH>:BALanced:BIAS -2.5 V ... +2.5 V
The command sets the bias. A DC voltage is superimposed upon the symmetric I and Q signal.
Example: OUTP:ANAL:BAL:BIAS -2.5V
*RST value
0
[SOURce:]OUTPut:ANALog<CH>:BALanced:BIAS:STATe ON | OFF
The command switches on/off the bias amplifier.
Example: OUTP:ANAL:BAL:BIAS:STAT ON
*RST value
OFF
