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)
