The N934xC HSA has a total of four traces and supports
simultaneous detectors including peak, average, sample,
negative peak, and the normal detector. Plus the N934xC
HSA supports simultaneous detectors, meaning that dif-
ferent detectors can be used on four different traces in a
single sweep—this will greatly increase the throughput to
measure crest factor of pseudo-noise signals, as well as
amplifiers.
In this demonstration, we will turn on three traces with
peak, RMS, and neg peak detectors.
