:DISPlay:AMPLitude:LEVel?

Description

For the Jitter/Noise Mode graphs Composite Histogram, Aliased Noise Spectrum, and SER Amplitude Bathtub, selects the type of signal levels to include (and thereby exclude) from the amplitude measurement algorithm: ONE, ZERO, or BOTH Levels. These are the levels from which data is acquired for calculating amplitude results. However, because the Aliased Noise Spectrum graph can only be set to use one or zero levels, if BOTH is selected, this graph defaults to using zero levels while all other graphs use both levels. The default setting is BOTH.

ALL

Selects all amplitude levels on an NRZ or PAM4 waveform.

BOTH (deprecated)

Selects levels zero and one on NRZ waveforms. For new programs, use the ALL argument.

THRee

Selects amplitude level three on a PAM4 waveform.

TWO

Selects amplitude level two on a PAM4 waveform.

ONE

Selects amplitude level one on an NRZ or PAM4 waveform.

ZERO

Selects amplitude level zero on an NRZ or PAM4 waveform.
