Measure Commands 24
Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference 639
:MEASure:VUPPer
Command :MEASure:VUPPer [<source>]
The :MEASure:VUPPer command measures the voltage value at the upper
threshold of the waveform. Sources are specified with the
MEASure:SOURce command or with the optional parameter following the
:MEASure:VUPPer 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.
Example This example measures the voltage at the upper threshold of the
waveform.
myScope.WriteString ":MEASURE:VUPPer CHANNEL1"
Query :MEASure:VUPPer? [<source>]
The :MEASure:VUPPer? query returns the measured upper threshold value
of the selected source.
Returned Format
[:MEASure:VUPPer] <value>[,<result_state>]<NL>
<value> Voltage at the upper 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 places the value of the voltage at the upper threshold of the
waveform in the numeric variable, varValue, then prints the contents of
the variable to the computer's screen.
myScope.WriteString ":SYSTEM:HEADER OFF" ' Response headers off.
myScope.WriteString ":MEASURE:VUPPER? CHANNEL1"
