® Waveform setup R&S RTB2000 Vertical setup Threshold A threshold is used for digitization of analog signals. If the signal value is higher than the threshold, the signal state is high (1 or true for the Boolean logic).

There are two general methods to build the waveform record: sample decimation and waveform arithmetic. Sample decimation reduces the data stream of the ADC to a stream of waveform points with lower sample rate and a less precise time resolution.

® Trigger R&S RTB2000 Pattern trigger Signal Selects the polarity of the signal. Note that the sync pulse has the opposite polarity. If the video modulation is positive, the sync pulses are negative. If the modulation is neg- ative, sync pulses are positive. The edges of the sync pulses are used for triggering, therefore incorrect polarity setting causes a sporadic triggering by the video informa- tion.
