SCPI Commands for the Counter
3–70
VX4101A MultiPaq Instrument User Manual
comparator 2 level will be set to +.25 V for a rise time measurement. For fall
time, the reverse is set.
This command will modify the following:
function - set to RTIMe or FTIMe
aperture - described below
aperture/events mode - set to APERture
The input channel attenuation, offset, gain, level and slope can be modified
If neither of the optional arguments are used:
aperture is set to the default value
If only the <expected value> argument is used:
aperture is set to the default value
If both <expected value> and <resolution> are used the aperture is calculated as
follows:
aperture + 10
(–9)logtexpectedu–logtresolutionu)
with a minimum of 1e–8 and a maximum of 5 seconds. A longer aperture may
be set with the SENSe:RTIMe:APERture command.
CONFigure[1|2]([:SCALar]|:ARRay):TINTerval [<array size>[,expected value>[,<res-
olution>]]]
This command sets the Counter to make a time interval measurement. This
measurement is made between input channels 1 and 2. The CONFigure suffix
selects the input channel for the beginning of the interval. The end of the interval
will be from the remaining channel. The measurement is made from the first
detected rising edge on the first channel to the first following rising edge on the
second channel. If the <expected value> argument is used, the expected period of
the input signal should be used, not the expected time interval.
This command will modify the following:
function - set to TINT
aperture - described below
aperture/events mode - set to APERture
If autosetup mode is ON or ONCE, the input channel attenuation, offset, gain,
level and slope can be modified
If neither of the optional arguments are used:
aperture is set to the default value
