24 Measure Commands
:MEASure:VLOWer
Command :MEASure:VLOWer [<source>]
The :MEASure:VLOWer command measures the voltage value at the lower
threshold of the waveform. Sources are specified with the
:MEASure:SOURce command or with the optional parameter following the
:MEASure:VLOWer command.
<source> {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.
<N> CHANnel<N> is an integer, 1 - 4.
FUNCtion<N> and WMEMory<N> are:
An integer, 1 - 4, representing the selected function or waveform memory.
Query
:MEASure:VLOWer?
The :MEASure:VLOWer? query returns the measured lower threshold of the
selected source.
Returned Format
[:MEASure:VLOWer] <value>[,<result_state>]<NL>
<value> Voltage value at the lower threshold.
<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 voltage at the lower threshold of the
waveform to the numeric variable, varVlower, then prints the contents of
the variable to the computer's screen.
myScope.WriteString ":SYSTEM:HEADER OFF" ' Response headers off.
myScope.WriteString ":MEASURE:VLOW? CHANNEL1"
varVlower = myScope.ReadNumber
Debug.Print FormatNumber(varVlower, 0)
