Multiple traces and simultaneous detectors

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 different 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.
