Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide 151
Preliminary Basic Digital Operation (Option 651/652/654)
Preliminary Using Waveform Markers
Sample range begins on first point of signal
Negative range set between signal and
off time
Example of Incorrect Use
Waveform: 1022 points
Marker range: 110–1022
Marker polarity: Negative
This figure shows that a negative polarity marker goes low during
the marker on points; the marker signal goes high during the off
points. The ALC samples the waveform during the off marker
points.

Sampling both on and off time sets the modulator circuitry
incorrectly for higher signal levels. Note the increased amplitude
at the beginning of the pulse.
