Attributes:

Name	Description
DeviceFirmwareVersionScalar: DevString	Firmware version of the delay generator.
DeviceSerialNumberScalar: DevString	Serial number of the delay generator.
BurstDelayScalar: DevDouble	The added insertion delay from the trigger to the first delay cycle when in burst mode.
BurstPeriodScalar: DevDouble	The period between delay cycles when in burst mode.
BurstCountScalar: DevULong	The number of delay cyles generated on each trigger when in burst mode. The valid range covers [1..2^32-1].
BurstModeScalar: DevBoolean	The delay generator will generate a burst of N delay cycles on each trigger when enabled.
TriggerPrescaleScalar: DevULong	This is a divider to the original trigger frequency. If set to values > 1, only every Nth trigger will initiate a delay cyle. The valid range covers [1..2^30-1], 1 will disable the feature. Makes use of the advanced triggering mode when.
TriggerHoldoffScalar: DevDouble	The minimum allowed time between successive triggers. For example, if the trigger holdoff is set to 10 ms, then successive triggers will be ignored until at least 10 ms have passed since the last accepted trigger. Makes use of the advanced triggering mode.
TriggerThresholdScalar: DevFloat	The Ext Trig input threshold range is +-3.5 VDC.
TriggerRateScalar: DevDouble	The frequency of the trigger generator used in internal mode. It can generate triggers at rates from 100 uHz to 10 MHz with 1 uHz resolution.
TriggerModeScalar: pogoDsl:EnumType	Int - Internal triggering at rates from 100 µHz to 10 MHz. ExtRisingEdge - External triggering on rising edges. ExtFallingEdge - External triggering on falling edges. SingleExtRisingEdge - Externally triggered single shot on a rising edges. Execute SingleShot command to arm the trigger. SingleExtFallingEdge - Externally triggered single shot on a falling edges. Execute SingleShot command to arm the trigger. Single - Single shot triggering. Initiated manually on the device or by executing the SingleShot command. Line - Trigger at the power line frequency.

Commands:

Name	Description
WriteReadInput: DevString Output: DevString	Writes the argument string to the delay generator and returns the answer.
SaveSettingsInput: DevUShort Output: DevVoid	Saves the current instrument settings to location [1..9].
LoadSettingsInput: DevUShort Output: DevVoid	Reads back the previously saved instrument settings from location [1..9].
LoadDefaultsInput: DevVoid Output: DevVoid	Resets the device to it`s default settings.
SingleShotInput: DevVoid Output: DevVoid	When the DG645 is configured for single shot triggers, this command initiates a single trigger. When it is configured for externally triggered single shots, this command arms the DG645 to trigger on the next detected external trigger.
StatusInput: DevVoid Output: ConstDevString Device status	This command gets the device status (stored in its device_status data member) and returns it to the caller.
StateInput: DevVoid Output: State Device state	This command gets the device state (stored in its device_state data member) and returns it to the caller.

Pipes:

Properties:

Name	Description
AutoReconnectDevBoolean	Whether the server will automatically try to reconnect on errors.
HostDevString	Hostname or IP address to the device.
