Measure Commands 25
Agilent Infiniium 9000 Series Oscilloscopes Programmer's Reference 689
:MEASure:THResholds:SERial:ABSolute
Command :MEASure:THResholds:SERial:ABSolute <source>,
<upper_volts>,<middle_volts>,<lower_volts>
The :MEASure:THResholds:SERial:ABSolute command sets the upper level,
middle level, and lower level voltages that are used for protocol decode.
<source> {ALL | CHANnel<N> | FUNCtion<F> | WMEMory<N> | DIGital<M> |
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.
<upper_volts>
<middle_volts>
<lower_volts>
A real number specifying voltage thresholds.
Example This example sets the custom voltage thresholds to 0.9 volts for the upper
level, 0.5 volts for the middle level and 0.1 volts for the lower level on
channel 2.

Query :MEASure:THResholds:SERial:ABSolute? <source>
The :MEASure:THResholds:SERial:ABSolute? query returns the current
settings for upper level, middle level, and lower level voltages for the
custom thresholds.
NOTE
These serial threshold settings are used for protocol decode.
