Scale coupling
If enabled, the vertical scales of P
, N, dif
ferential and common mode waveforms are
coupled. The scales are related as follows:
VertScale
P
= VertScale
N
= VertScale
CM
= VertScale
Diff
/2
You can disable the scale coupling and set an individual scale for each waveform.
Remote command:
DIFFerential<m>:COUPling on page 1381
Offset
Sets the offset of differential and common mode waveforms.
Vertical settings of P and N output are the vertical settings of the input channels.
Remote command:
DIFFerential<m>:COMMon:OFFSet on page 1382
DIFFerential<m>:DIFFerential:OFFSet on page 1382
Position
Sets the vertical position of differential and common mode waveforms.
Vertical settings of P and N output are the vertical settings of the input channels.
Remote command:
DIFFerential<m>:COMMon:POSition on page 1382
DIFFerential<m>:DIFFerential:POSition on page 1382
5.8.3 Deembedding of differential signals
To remove the parasitic effects of the measurement setup from the measured signal,
you can use deembedding for differential signals. Deembedding requires option
R&S RTO6-K121.
The deembedding of differential signals is represented by one or more 4-port input
components. You can activate deskewing, and set a skew time.
See also: Chapter 20, "Deembedding (option R&S RTO6-K121)", on page 1199.
1. On the "Vertical" menu, select "Differential Signals".
2. Select the input channels of the positive and negative signal.
3. Enable the differential signal.
4. Select "Deembedding".
5. Select the channel subtab of the positive input.
6. On the "Setup" tab, enable deembedding for the channel.
7. On the "Input" component, select "Configure".
8. If necessary, activate "Use skew offset". Use the deskewing if the P and N wave-
forms are not correctly aligned.
