●
Specifies the transferable spectrum for other waveforms. E.g. with square wave
signals, the fifth harmonic should still be within the bandwidth for a high signal
integrity.
●
Determines the minimum measurable signal rise time. The rise time t
rise
of the
probe is inversely proportional to its bandwidth. The following approximation

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-ZS60 active voltage probe. All frequency compo-
nents are transferred with the same gain so that the input signal is displayed without
distortion.
