● Probing on ground-referenced signals. In this case, the common mode com-
ponent is always equal to half of the input voltage.

Dynamic Range and Operating Voltage Window

Two separate specifications are necessary in order to characterize the permissi-
ble input voltage range of a differential voltage probe:
● The dynamic range (or "differential mode range") designates the maximum
differential voltage V
nal pin.
● At the same time, the two voltage values at each of the two signal pins V
V referenced to the common ground must not exceed a specific limit value.
n
This limitation is referred to as the operating voltage window (some manufac-
turers also use the less precise term "common mode range" for the same
parameter).
If one of these ranges is exceeded, an unwanted signal clipping may occur.
