●
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
applies:
4.3 Step Response
In addition to bandwidth, a constant amplitude frequency response of the probe is deci-
sive for high signal integrity. All frequency components are transferred with the same
gain so that the input signal is displayed without distortion.
Figure 4-5 and Figure 4-6 show a typical step response of all R&S RT-ZHD differential
probes up to 30 ns. The propagation delay is normalized to the beginning of the step.
The amplitude is normalized to the steady state value.
