Measure Commands 25
Agilent Infiniium 9000 Series Oscilloscopes Programmer's Reference 695
:MEASure:THResholds:SERial:PERCent
Command :MEASure:THResholds:SERial:PERCent <source>,<upper_pct>,<middle_pct>,<lo
wer_pct>
The :MEASure:THResholds:SERial:PERCent command sets the upper level,
middle level, and lower level voltages as a percentage of the top and base
voltages which are used for protocol decode.
<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.
<upper_pct>
<middle_pct>
<lower_pct>
A real number specifying upper percentage from - 24.8 to 125.0 A real
number specifying the middle percentage from - 24.9 to 124.9. A real
number specifying the lower percentage from - 25.0 to 125.8
Example This example sets the percentage to 100% for the upper level, 50% for the
middle level and 0% for the lower level on channel 2.

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