Enables/Disables the counter function

:Clear

TCNTS/GTNTS

Clears the active counter

the channel will be displayed
*Note: GCNTS will only work on units that have the
dual trigger option and the ? must be included in
the Sub-Command.

:STATe

0/1 or OFF/ON

Enables/Disables the output for all channels. This
command is the same as pressing the Run/Stop
button.

:PERiod

50[ns]

– 5000[s]

:OPTion

FORCE / LAST

Allows the user to set the behavior of the
instrument when synchronization to the external
clock is lost and resync'd. "Force" will cause the
unit to disable the channels as soon as the lock is
lost, and "Last" will cause the unit to resume with
whatever the last mode was when resync'd.
*Note: Only applies when ICLock is XPL mode
