Notes
:PULSe[0]
Command to change the units global settings, this is the same
as using the :SPULse command
:GATe
:MODe
DISable, PULSeinh,
OUTPutinh,
CHPUlseinh,
CHOUtputinh
Sets the gate mode for the unit: When in pulse inhibit mode if
the pulse has started before the gate is seen the output pulse
will finish, but any further pulses will be prevented, In output
inhibit mode if a pulse has started it will be truncated as soon
as the gate signal is seen and will prevent any further pulses,
and when in channel mode each channel can be setup
individually (be aware of insertion delay for each mode, this is
listed in the specifications)
ENABLE / DISable
In Trigger or ReArm mode the Mode command is the
enable/disable. When the gate is changed to Trigger with the
Smode command it will default to disabled, in order to utilize
this function it first must be enabled with the Mode command
SMODe
GATe, TRIG, or
RARM
Smode commands are part of the Dual Trigger option and are
only available on units with the Dual Trigger Module installed.
:LOGic
LOW / HIGH
Choose active Low (will allow pulses when low) or active High
(will allow pulses when high) This is also the setting used for
the ReArm option.
:EDGe
RISing / FALLing
Choose the edge to trigger on (only used when the option for
the gate to be a second trigger input is enabled)
:LEVel
.20 V - 15 V
Choose the gate level threshold to trigger on, this should be
set to ~ 50% of the input potential

Notes
*IDN
?
Query only. Returns model, serial number, firmware version, and FPGA
version numbers.
*RCL
0-16
RECALL
*RST
This command will RESET the unit, perform a stop and a Recall 0
*SAV
1-16
SAVE
*TRG
Create a soft Trigger on the Trigger Input
*GTG
Create a soft Trigger on the Gate input (Only active when the dual trigger
option is enabled)
*GTE
0/1
Sets a software gate state. Equal to setting Gate input to Active High/Low
*LBL
?
Used to query the label of the last saved or recalled configuration.
String Value
String must be in double quotes and no longer than 14 characters. Command
must be followed by a *sav [1/2/n] command to take effect.
*ARM
Resets all channel counters simultaneously when the channels are in either
single shot or burst mode.
*Note: The system must be in continuous mode (this command is functionally
the same as pressing the Run/Stop button).
