Determines the minimum measurable signal rise time. The rise time t
rise
of the
probe is inversely proportional to its bandwidth. The following approximation
applies:

In addition to bandwidth, a constant amplitude/frequency response of the probe is
decisive for high signal integrity. The Figure 4-2 shows the typical amplitude/
frequency response of an R&S RT‑ZS10/20/30 active voltage probe. All fre-
quency components are transferred with the same gain so that the input signal is
displayed without distortion.
The Figure 4-3 shows a typical step response of an R&S RT‑ZS10/20/30 active
voltage probe.
