Enable
Activates the differential signal.
Remote command:
DIFFerential<m>:STATe on page 1244
P, N
Select the analog input channel of the positive and negative signal.
You can switch the channels with the arrow button. Using the same input channel for
both differential signals is not possible.
Remote command:
DIFFerential<m>:PSIGnal[:SELect] on page 1244
DIFFerential<m>:NSIGnal[:SELect] on page 1244
Output: P, N, Differential, Common
Select the waveforms that are displayed as result of differential processing.
The number of output waveforms per differential signal depends on the deembedding:
●
No deembedding: 2 output waveforms.
●
Deembedding by software: up to 4 output waveforms. All output waveforms can be
displayed at the same time.
●
Realtime deembedding: 1 output waveform. It can either be the deembedded differ-
ential, common-mode, positive single-ended or negative single-ended waveform.
In the diagram, you see the output waveforms, and the signal icons of the input chan-
nels are grayed out. The input channels are only visible if "P" or "N" are selected as
output.
"P", "N"
Displays the waveform of the positive or negative input signal.
Without deembedding, the input channel is shown directly, no addi-
tional waveform is created. If differential deembedding is active, you
always see the deembedded waveforms, but never the captured input
signal.
"Differential"
Displays the differential signal as a new waveform.
"Common"
Displays the common mode signal as a new waveform.
Remote command:
DIFFerential<m>:AOUTput on page 1244
DIFFerential<m>:BOUTput on page 1244
If deembedding by software is active, use the following commands:
DIFFerential<m>:COMMon:STATe on page 1245
DIFFerential<m>:DIFFerential:STATe on page 1245
DIFFerential<m>:NSIGnal:STATe on page 1245
DIFFerential<m>:PSIGnal:STATe on page 1245
Vertical scale, Offset
Vertical scale and offset of differential and common mode waveforms can be set
directly in the differential setup, or in the "Vertical Setup" of differential signals. See:
"Scale" on page 205 and "Offset" on page 205.
Vertical settings of P and N output are the vertical settings of the input channels.
