Accessing Marker Utilities - Agilent Technologies E8257D PSG User Manual

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.
