Command Descriptions
Arguments
<array size> sets the number of samples. One complete group requires an
array size of 4. It can contain 4 or 8 numeric values depending on whether
is
OFF
or
ON
.
MEASure{:FALL:TIME|:FTIM}? (Query Only)
The transition time from 90% to 10% of the signal amplitude is measured.
The measurement is always a single measurement and the Auto-trigger is always
on, setting the trigger levels to 90% and 10% of the amplitude. If you need an
average transition time measurement, or other trigger levels, use the SENSe
subsystem and manually set trigger levels instead.

Syntax
MEASure{:FALL:TIME|:FTIM}?[ [<lower threshold> [,<upper
threshold>[,<expected value>[,<resolution>]]]] [,(@1|@2)] ]
Arguments
<LOWER THRESHOLD>
,
<UPPER THRESHOLD>
,
<EXPECTED VALUE>
and
<RESOLUTION>
are all ignored by the instrument.
<(@1)>
or
<(@2)>
is the measurement channel (input A or input B).
MEASure:FREQuency? (Query Only)
Traditional frequency measurements. The instrument uses the <expected value>
and <resolution> to calculate the Measurement Time (
).
Group
Measurement
Syntax
MEASure:FREQuency?[ [<expected value>[,<resolution>]]
[,<(@{1|2|3|4|6})>]]
Arguments
<expected value> is the expected frequency,
<resolution> is the required resolution.
<(@{1|2|3|4|6})> is the channel to measure on, where:
(@1)
means input A
3
(@2)
means input B
3
(@3)
means input C (RF input option),
