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

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

1-1,000,000

Changes the number of pulses to output when the

system is in burst mode.

*Note: The commas should be omitted.

:PCOunter

1-1,000,000

Changes the number of on pulses to output when

the system is in Duty Cycle mode.

*Note: The commas should be omitted.

:OCOunter

1-1,000,000

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
