Setting the Gate Time
A measurement gate time can be specified directly with the command:
[SENSe:]FREQuency:GATE:TIME {<time>|MINimum|MAXimum|DEFault}
[SENSe:]FREQuency:GATE:TIME? {MINimum|MAXimum|DEFault}
CONFigure
time according to their optional expected value and resolution parameters.
Specifying these parameters or using default values with these commands
simplifies counter programming. However, setting/changing the gate time
separate from the
gate time while preserving other configuration settings.
