Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference 675
:MEASure:VBASe
Command
:MEASure:VBASe [<source>]
The :MEASure:VBASe command measures the statistical base of the
waveform. Sources are specified with the :MEASure:SOURce command or
with the optional parameter following the :MEASure:VBASe command.
<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.
Example
This example measures the voltage at the base of the waveform.
myScope.WriteString ":MEASURE:VBASE CHANNEL1"
Query
:MEASure:VBASe? [<source>]
The :MEASure:VBASe? query returns the measured voltage value at the
base of the specified source.
Returned Format
[:MEASure:VBASe] <value>[,<result_state>]<NL>
<value>
Voltage at the base of 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 current voltage at the base of the waveform to
the numeric variable, varVoltage, then prints the contents of the variable
to the computer's screen.
myScope.WriteString ":SYSTEM:HEADER OFF" ' Response headers off.
myScope.WriteString ":MEASURE:VBASE? CHANNEL1"
varVoltage = myScope.ReadNumber
Debug.Print FormatNumber(varVoltage, 0)
