Measure Commands
VPP
Measures the absolute minimum voltage present on the selected source waveform. The
source is specified with the MEASure:SOURce command or with the optional parameter fol-
lowing the VMIN command. <source> is {CHANnel<N> | FUNCtion<N> | RESPonse<N> |
WMEMory<N>} where <N>, for channels is dependent on the type of plug-in and its location
in the instrument. For functions: 1 or 2. For waveform memories (WMEMORY): 1, 2, 3, or 4.
For TDR responses: 1, 2, 3, or 4.
Mode Oscilloscope and TDR modes.
Query :MEASure:VMIN? [<source>]
The query returns the measured absolute minimum voltage present on the selected source
waveform.
Returned Format [:MEASure:VMIN] <value>[,<result_state>]<NL>
<value> is the absolute minimum voltage present on the waveform. If SENDvalid is ON, the
<result_state> is returned with the measurement result. Refer to Table 18-4 on page 18-39
for a list of the result states.
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASURE:VMIN?”
VPP
Command :MEASure:VPP [<source>]
Measures the maximum and minimum voltages on the selected source, then calculates the
peak-to-peak voltage as the difference between the two voltages. Sources are specified with
the MEASure:SOURce command or with the optional parameter following the VPP command.
<source> is {CHANnel<N> | FUNCtion<N> | RESPonse<N> | WMEMory<N>} where <N>, is
an integer, from 1 through 4.
Mode Oscilloscope and TDR modes only
Query :MEASure:VPP? [<source>]
The query returns the specified source peak-to-peak voltage.
Returned Format [:MEASure:VPP] <value>[,<result_state>]<NL>
<value> is the peak-to-peak voltage of the selected source. If SENDvalid is ON, the
<result_state> is returned with the measurement result. Refer to Table 18-4 on page 18-39
for a list of the result states.
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;":MEASURE:VPP?"
VRMS
Command :MEASure:VRMS {CYCLe | DISPlay}, {AC | DC} [,<source>]
Measures the RMS voltage of the selected waveform by subtracting the average value of the
waveform from each data point on the display. Sources are specified with the MEA-
Sure:SOURce command or with the optional parameter following the VRMS command.
The CYCLe parameter instructs the RMS measurement to measure the RMS voltage across
the first period of the display. The DISPLay parameter instructs the RMS measurement to
measure all the data on the display. Generally, RMS voltage is measured across one waveform
