24 Measure Commands
:MEASure:VAMPlitude
Command :MEASure:VAMPlitude [<source>]
The :MEASure:VAMPlitude command calculates the difference between the
top and base voltage of the specified source. Sources are specified with
the :MEASure:SOURce command or with the optional parameter following
the :MEASure:VAMPlitude 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 calculates the difference between the top and base voltage of
the specified source.
myScope.WriteString ":MEASURE:VAMPLITUDE CHANNEL1"
Query :MEASure:VAMPlitude? [<source>]
The :MEASure:VAMPlitude? query returns the calculated difference
between the top and base voltage of the specified source.
Returned Format
[:MEASure:VAMPlitude] <value>[,<result_state>]<NL>
<value> Calculated difference between the top and base voltage.
<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 current Vamplitude value 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:VAMPLITUDE? CHANNEL1"
varValue = myScope.ReadNumber
Debug.Print FormatNumber(varValue, 0)
