Identification of the Probe
When the probe is connected to the oscilloscope, the oscilloscope recognizes the
probe and reads out the probe-specific parameters.
The complete probe information is shown in the probe settings dialog. For more
information, refer to the user manual of your oscilloscope.

MultiMode
The R&S
RT-ZM probe family features the MultiMode function which allows you
to switch between single-ended, differential and common mode measurements
without reconnecting or resoldering the probe.
Four different input voltages can be measured with the MultiMode feature:
●
P-Mode
: (pos.) Single-ended input voltage (V
p
)
Voltage between the positive input terminal and ground
●
N-Mode
: (neg.) Single-ended input voltage (V
n
)
Voltage between the negative input terminal and ground
●
DM-Mode
: Differential mode input voltage (V
dm
)
Voltage between the positive and negative input terminal
●
CM-Mode
: Common mode input voltage (V
cm
)
Mean voltage between the positive and negative input terminal vs. ground
In the N-Mode, the signal at negative input terminal is not inverted.
