25 Measure Commands
:MEASure:VMIDdle
Command :MEASure:VMIDdle [<source>]
The :MEASure:VMIDdle command measures the voltage level at the middle
threshold of the waveform. Sources are specified with the
:MEASure:SOURce command or with the optional parameter following the
:MEASure:VMIDdle command.
Query
:MEASure:VMIDdle? [<source>]
The :MEASure:VMIDdle? query returns the voltage value at the middle
threshold of the waveform.
<source> {CHANnel<N> | FUNCtion<F> | 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.
<N> CHANnel<N> is an integer, 1- 4.
WMEMory<N> is an integer, 1- 4.
<F> FUNCtion<F> is an integer, 1- 16.
Returned Format
[MEASure:VMIDdle] <value>[,<result_state>]<NL>
<value> The middle voltage present on the waveform.
<result_state> If SENDvalid is ON, the result state is returned with the measurement
result. See the :MEASure:RESults table in this chapter for a list of the
result states.
Example This example returns the measured middle voltage on the waveform to the
numeric variable, varMiddle, then prints the contents of the variable to the
computer's screen.
myScope.WriteString ":SYSTEM:HEADER OFF" ' Response headers off.
myScope.WriteString ":MEASURE:VMID? CHANNEL1"
varMiddle = myScope.ReadNumber
Debug.Print FormatNumber(varMiddle, 0)
