"DM"
Differential mode input voltage (V
dm
), the voltage between the positive
and negative input terminal.
"CM"
Common mode input voltage (V
cm
), the mean voltage between the
positive and negative input terminal vs. ground.
"P"
Positive single-ended input voltage (V
p
). The voltage between the
positive input terminal and ground.
"N"
Negative single-ended input voltage (V
N
). The voltage between the
negative input terminal and ground.
Remote command:
DM Offset, CM Offset, P Offset, N Offset
Compensate offset voltages. Available offsets depend on the selected probe mode.
The offset of the selected probe mode is used as channel offset and considered auto-
matically for correction. For example, in CM mode, the common mode offset is used as
channel offset. See also:
"DM Offset"
Compensates a DC voltage applied between the positive (V
p
) and the
negative (V
n
) input terminal at the probe tip.
"CM Offset"
Compensates a DC voltage applied to both input terminals refer-
enced to ground. See also:
"P Offset"
Compensates a DC voltage applied to the positive input terminal (V
p
)
referenced to ground.
"N Offset"
Compensates a DC voltage applied to the negative input terminal (V
n
)
referenced to ground.

Deembedding for modular probes
Deembedding removes the parasitic effects of the measurement setup from the mea-
sured signal. These effects are typically increasing when signal frequency increases.
Thus, deembedding is useful or even necessary when measuring signals of 4 GHz fre-
quency or higher.
Access: "Vertical" menu > "Probe Setup" > "Probe Deembedding"
Select probe tip module, Pin spacing
Selects the tip module that is used for measurement.
