Chapter 3: Remote Operation
3-10 2400 Series Operation Manual, 33237 Revision A, May 2004
3.4 GT2400 Specific Commands
*OPC
Operation Complete Causes the Operation Complete bit (that is, Bit 0 of the
Standard Event Status Register) to be set to 1 when all
pending selected device operations have been finished
*OPC?
Operation Complete Places an ASCII character 1 into the device’s output
queue when all pending selected device operations
have been finished. Unlike the *OPC command, the
*OPC? query does not affect the OPC Event bit in the
Standard Event Status Register (ESR)
*RST
Reset Sets the device-specific functions to a known state (the
power-on state) that is independent of the past-use
history of the device. The command does not reset any
part of the status reporting system
*SRE n
Service Request Enable Sets and enables the value of the Service Request Enable
Register
Range of n: 0 to 255
*SRE?
Service Request Enable Returns the value set by the *SRE command for the
Service Request Enable Register
*STB?
Read Status Byte Returns the value of the current state of the Service
Request Enable Register (Status Byte Register)
*TST?
Self-Test Self-Test Query. It returns '0' if the test succeeds, and '1' if
the test fails
The test sets a predefined group of CW frequencies and
power levels. After each frequency and power is set, the
firmware reads the status of synthesizer's LOCK/LEVEL
status. If failing the lock/level, the test is failed. In order
to avoid damage to the device the GT2400 is connected
to, maximum attenuation is set box if it is available. The
system will be restored to the pre-test condition upon
completion
*WAI
Wait-to-Continue Causes the synthesizer to complete all pending tasks
before executing any additional commands
Command Name Description
*RCL n
Recall Instrument State Recalls a previously saved instrument state from memory
Range of n: 0 - 9
*SAV n
Save Instrument State Saves the current instrument state to memory
Range of n: 0 - 9
*TRG
Trigger Device Triggers the synthesizer if BUS is the specified trigger
source.
