5 Triggering and Gating
Gate Stop Hold Off Source
The gate stop holdoff source and its parameters are set with the commands:
[SENSe:]GATE:STOP:HOLDoff:SOURce {IMMediate|EVENts|TIME}
[SENSe:]GATE:STOP:HOLDoff:SOURce?
(query form)
- holdoff source
IMMediate
disables the hold off settings and no gate holdoff
occurs. The gate closes immediately after the gate stop parameters are satis-
fied.
CONFigure
and
MEASure
do not change the hold off source setting. Following
a reset (
*RST
) or instrument preset (
SYSTem:PRESet
or
Preset
key), hold off
source
IMMediate
is selected (disabled).
- hold off source
EVENts
holds off the gate stop (close) until a specified num-
ber of events (edges) as configured by the
INPut
subsystem occur on the input
channel . For two-channel time interval measurements, hold off events are
counted on the ‘stop’ channel. For frequency ratio measurements, hold off
events are counted on the ‘denominator’ channel.
The number of events is specified with the command:
[SENSe:]GATE:STOP:HOLDoff:EVENts {<count>|MINimum|
MAXimum|DEFault}
[SENSe:]GATE:STOP:HOLDoff:EVENts? (query form)
