Measure Commands
VAVerage
<value> is the cCalculated difference between the top and base voltage. If SENDvalid is ON,
the <result_state> is returned with the measurement result. Refer to Table 18-3 on
page 18-30 for a list of the result states.
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;":MEASURE:VAMPLITUDE?2"
VAVerage
Command :MEASure:VAVerage {CYCLe | DISPlay} [,<source>]
Calculates the average voltage over the displayed waveform. The source is specified with the
MEASure:SOURce command or with the optional parameter following the VAVerage com-
mand. The CYCLe parameter specifies to measure the average voltage across the first period
of the display. This option is valid in oscilloscope mode only. The DISPlay parameter specifies
to measure all the data on the display. This option is valid in both oscilloscope and TDR
modes. The <source> is {CHANnel<N> | FUNCtion<N> | WMEMory<N> | RESPonse<N>}
where <N> is an integer, from 1 through 4.
Mode Oscilloscope and TDR (DISPlay option only) modes.
Query :MEASure:VAVerage? {CYCLe | DISPlay}, [<source>]
The query returns the calculated average voltage of the specified source.
Returned Format [:MEASure:VAVerage] <value> [,<result_state>]<NL>
<value> is the calculated average voltage. If SENDVALID is ON, the <result_state> is
returned with the measurement result. Refer to Table 18-3 on page 18-30 for a list of the
result states.
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASURE:VAVERAGE? DISPLAY”
VBASe
Command :MEASure:VBASe [<source>]
Measures the statistical base of the waveform. The source is specified with the MEA-
Sure:SOURce command or with the optional parameter following the VBASe 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
<n> is 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:VBASe? [<source>]
The query returns the measured voltage value at the base of the specified source.
Returned Format [:MEASure:VBASe] <value>[,<result_state>]<NL>
<value> is the voltage at the base of the waveform. If SENDvalid is ON, the <result_state> is
returned with the measurement result. Refer to Table 18-3 on page 18-30 for a list of the
result states.
Example 10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASURE:VBASE?”
