Notes:
:PULSe[0]
Command to change the units’ global settings, this
is the same as using the :SPULse command
:COUNter
Subsystem. Contains commands to define the
Counter function.
:STATe
0/1 or OFF/ON
Enables/Disables the counter function
:Clear
TCNTS/GTNTS
Clears the active counter
*Note: Standard units only have the trigger counter.
:COUNt?
TCNTS/GTNTS
Reports the clock pulses output except in single
shot mode, in this case the trigger pulses input on
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]
Sets the T
0
period. The command should be sent
without units. If for example 50ns is desired the
parameter sent should be 50e-9, or the decimal
equivalent.
:MODe
NORMal/SINGle/
BURSt/DCYCle
Changes the system output mode.
:BCOunter
1-9,999,999
Changes the number of pulses to output when the
system is in burst mode.
*Note: The commas should be omitted.
:PCOunter
1-9,999,999
Changes the number of on pulses to output when
the system is in Duty Cycle mode.
*Note: The commas should be omitted.
:OCOunter
1-9,999,999
Changes the number of off pulses to suppress
when the system is in Duty Cycle mode.
*Note: The commas should be omitted.
:ICLock
Submenu for selecting the clock source
:MODe
INT / EXT / XPL
Changes the source and type of the system clock.
INT is internal, EXT is external, and XPL is external
with phase-locked-loop.
:RATe
10–100[MHz]
Changes the frequency of input clock signal the
unit should expect, has a 1MHz resolution
*Note: This menu is only active in EXT mode.
:LEVel
.02 - 2.5[V]
Choose the input level threshold to trigger on ~
50% of the input potential.
*Note: If the triggering threshold is not set correctly
the unit responses are undetermined.
: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
