or cycle, however, measuring multiple cycles may be accomplished with the DISPLay option.
The DISPlay parameter is also useful when measuring noise. The AC parameter is used to
measure the RMS voltage subtracting out the DC component. The DC parameter is used to
measure RMS voltage including the DC component. The AC RMS, DC RMS, and VAVG param-
eters are related as in the following formula:
DCVRMS

= ACVRMS

+ VAVG

<source> is {CHANnel<N> | FUNCtion<N> | WMEMory<N>} and <N> is 1, 2, 3, or 4.
Mode
Oscilloscope mode only.
Query
:MEASure:VRMS? {CYCLe | DISplay}, {AC | DC} [,<source>]
The query returns the RMS voltage of the specified source.
Returned Format
[:MEASure:VRMS] <value>[,<result_state>]<NL>
<value> is the RMS voltage of the selected waveform. If SENDvalid is ON, the <result_state>
is returned with the measurement result. Refer to
for a list of the
result states.
Example
10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;":MEASURE:VRMS? CYCLE,AC"
VTIMe?
Query
:MEASure:VTIMe? <time> [,<source>]
Returns the measured voltage. <time> is the time interval between the trigger event and the
specified edge (oscilloscope mode) or the time interval between the reference plane and the
specified edge in TDR mode. <source> is {CHANnel<N> | FUNCtion<N> | RESPonse<N> |
WMEMory<N>} and <N> is an integer, from 1 to 4.
Mode
Oscilloscope and TDR modes.
Returned Format
[:MEASure:VTIMe] <value>[,<result_state>]<NL>
<value> is the voltage at the specified time. In oscilloscope mode, <time> is the time mea-
sured from the trigger event. In TDR mode, <time> is measured with respect to the reference
plane. If SENDvalid is ON, the <result_state> is returned with the measurement result. Refer
to
for a list of the result states.
Example
10 OUTPUT 707;”:SYSTEM:HEADER OFF”
20 OUTPUT 707;”:MEASURE:VTIME? 500E–3”
VTOP
Command
:MEASure:VTOP [<source>]
Measures the statistical top of the selected source waveform. The source is specified with the
MEASure:SOURce command or with the optional parameter following the VTOP command.
<source> is {CHANnel<N> | FUNCtion<N> | RESPonse<N> | WMEMory<N>}. <N>, for chan-
nels, 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:VTOP? [<source>]
