1) Initialize the instrument state before changing the setting.
For instrument setting of remote control, initialize the instrument state (sending “*RST”, etc.) and then set the
required state.
2) Command sequence
Generally, the setting command and query command should be transmitted separately. Otherwise, the returned
value of the query command will change according to the current instrument operation sequence.
3) Fault response
The service request must be sent by the instrument. The controller of the test system should be programmed to
guide the instrument to actively send the service request if required, so as to enable the corresponding service
interruption program.
4) Error queue
The error queue instead of the state register should be inquired once the service request is processed by the
controller program, so as to find more accurate causes. The queue should be always inquired in the controller
program test phase to obtain the commands sent by the controller to the instrument.
