Measure Commands 25
Agilent Infiniium 9000 Series Oscilloscopes Programmer's Reference 673
:MEASure:THResholds:METHod
Command :MEASure:THResholds:METHod <source>,{ABSolute | PERCent | HYSTeresis}
The :MEASure:THResholds:METHod command determines the way that the
top and base of a waveform are calculated for all of the measurements
that use them.
<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.
Example This example sets the method used to calculate the top and base of a
waveform to hysteresis.
myScope.WriteString ":SYSTem:HEADer OFF" ' Response headers off.
myScope.WriteString ":MEASure:THResholds:METHod CHANnel1,HYSTeresis"
Query :MEASure:THResholds:METHod? <source>
The :MEASure:THResholds:METHod? query returns the current method
being used to calculate the top and base of a waveform.
Returned Format
[:MEASure:THResholds:METHod <source>,] {ABSolute | PERCent | HYSTeresis}
NOTE
This command changes the threshold settings used for rise/fall time measurements,
protocol decode, and all other general-purpose measurements that use thresholds. To
change the settings used for these types of measurements individually, see:
