24 Measure Commands
:MEASure:VTIMe
Command :MEASure:VTIMe <time>[,<source>]
The :MEASure:VTIMe command measures the voltage at the specified time.
The time is referenced to the trigger event and must be on the screen.
When an FFT function is the specified source, the amplitude at the
specified frequency is measured. Sources are specified with the
:MEASure:SOURce command or with the optional parameter following the
:MEASure:VTIMe 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.
<time> A real number for time from trigger in seconds, or frequency in Hertz for
an FFT (when a function is set to FFT or a waveform memory contains an
FFT).
Query
:MEASure:VTIMe? <time>[,<source>]
The :MEASure:VTIMe? query returns the measured voltage or amplitude.
Returned Format
[:MEASure:VTIMe] <value>[,<result_state>]<NL>
<value> Voltage at the specified time. When the source is an FFT function, the
returned value is the vertical value at the horizontal setting passed in the
VTIMe <time> parameter. The time parameter is in Hertz when an FFT
function is the source.
<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 voltage at 500 ms in the numeric variable,
varValue, then prints the contents to the computer's screen.
