24 Measure Commands
:MEASure:THResholds:TOPBase:METHod
Command :MEASure:THResholds:TOPBase:METHod <source>,{ABSolute | HISTONLY | MINma
x | STANdard}
The :MEASure:THResholds:TOPBase:METHold command determines the
way that the top and base of a waveform are derived for all of the
measurements that use them.
<source> {ALL | CHANnel<N> | FUNCtion<N> | 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> is an integer, 1 - 4.
Example This example sets the method used to derive the top and base of a
waveform to the histogram method.
myScope.WriteString ":SYSTEM:HEADER OFF" ' Response headers off.
myScope.WriteString ":MEASURE:THRESHOLDS:TOPBASE:METHOD CHANNEL1,HISTONL
Y"
Query :MEASure:THResholds:TOPBase:METHod?
The :MEASure:THResholds:TOPBase:METHod? query returns the current
method being used to calculate the top and base of a waveform.
Returned Format
[:MEASure:THResholds:TOPBase:METHod] {ABSolute | HISTONLY | MINmax | STA
Ndard}
Example This example returns the method used to derive the top and base of a
waveform for channel 1.
myScope.WriteString ":SYSTEM:HEADER OFF" ' Response headers off.
myScope.WriteString ":MEASURE:THRESHOLDS:TOPBASE:METHOD CHANNEL1"
varMethod = myScope.ReadNumber
Debug.Print FormatNumber(varMethod, 0)
