The figure 5-3 shows a typical step response of an R&S RT-ZD40 differential
probe.
In addition to bandwidth, a constant amplitude frequency response of the probe is
decisive for high signal integrity. The
quency response of an R&S RT-ZD40 differential probe. All frequency compo-
nents are transferred with the same gain so that the input signal is displayed with-
out distortion.

Connection Inductance

The connection inductance L
contrast to the probe-specific bandwidth, the connection inductance mainly
depends on the type of connection that the user selects.
The connection inductance
● Increases with the length of the connection and the size of the resulting loop
area A.
See figure 5-4.
● Reduces the usable bandwidth and causes ringing with signals having a short
rise time (due a series resonance with the input capacitance).
