Dynamic range and operating voltage window
Two separate specifications are necessary to characterize the permissible input
voltage range of a R&S RT-ZM MultiMode probe.
Measurement mode Single-Ended P, Single-Ended N, or Common Mode
Dynamic Range
The dynamic range for single-ended (P-Mode, N-Mode) or common mode (CM-
Mode) measurements designates the maximum voltage (V
between each of the two input terminals (V
Differential measurement mode

Operating voltage window
(each pin to ground)
● The dynamic range for differential measurement (DM-Mode) designates the
maximum differential voltage V
negative signal terminal at the probe tip.
● At the same time, the two voltage values at each of the two signal terminals V
and V
referenced to the common ground must not exceed a specific limit
n
value. This limitation is referred to as the operating voltage window (some
manufacturers also use the less precise term "common mode range" for the
same parameter).
● If one of these ranges is exceeded, an unwanted signal clipping can occur.
When measuring differential signals, frequently change to common mode
measurement to check for unallowed common mode signals.
● The attenuation is automatically selected by the oscilloscope's "V/div" setting
