Agilent Infiniium 9000 Series Oscilloscopes Programmer's Reference 691
:MEASure:THResholds:SERial:HYSTeresis
Command :MEASure:THResholds:SERial:HYSTeresis <source>,<range>,<level>
The :MEASure:THResholds:SERial:HYSTeresis command sets the range and
level voltages that are used for protocol decode. The range is added to the
level to determine the upper level voltage. The range is subtracted from
the level to determine the lower level voltage. The level is the middle level
voltage.
<source> {ALL | CHANnel<N> | FUNCtion<F> | DIGital<M> | WMEMory<N> |
CLOCk | MTRend | MSPectrum | EQUalized}
MTRend and MSPectrum sources are only available if the oscilloscope has
the EZJIT option installed and the feature is enabled.
The CLOCk source is only available if the oscilloscope has the High Speed
Serial option installed and the feature is enabled.
The EQUalized source is only available if the oscilloscope has the High
Speed Serial option and the Serial Data Equalization option installed and
the features are enabled. This command uses the Feed- Forward Equalized
(FFE) signal as the source. Setting the source to ALL does not affect the
individual channel settings which is the behavior as the user interface.
<N> An integer, 1-4.
<F> An integer, 1-16.
<M> An integer, 0- 15. Digital channels are available on mixed-signal
oscilloscopes.
<range> A real number specifying voltage range for the hysteresis around the level
value.
<level> A real number specifying voltage level.
Example This example sets the hysteresis range to 0.9 volts and 0.1 volts for the
level on channel 2.

These serial threshold settings are used for protocol decode.
