To Determine When a Command Sequence is Completed
1 Send a device clear message to clear the function generator’s
output buffer (e.g.,
CLEAR 710
).
2 Clear the event registers with the
*CLS
(clear status) command.
3 Enable the “operation complete” bit (bit 0) in the Standard Event
register by executing the
*ESE 1
command.
4 Send the
*OPC?
(operation complete query) command and enter the
result to ensure synchronization.
5 Execute your command string to program the desired configuration,
and then execute the
*OPC
(operation complete) command as the last
command. When the command sequence is completed, the “operation
complete” bit (bit 0) is set in the Standard Event register.
6 Use a serial poll to check to see when bit 5 (standard event) is set in the
Status Byte summary register. You could also configure the function
generator for an
SRQ
interrupt by sending
*SRE 32
(Status Byte enable
register, bit 5).
