– To ensure synchronization when the bus source is selected, send the *WAI
(wait) command. When the *WAI command is executed, the power supply
waits for all pending operations to complete before executing any additional
commands. For example, the following command string guarantees that the
first trigger is accepted and is executed before the second trigger is
recognized.
– You can use the *OPC? (operation complete query) command or the *OPC
(operation complete) command to signal when the operation is complete. The
*OPC?
command returns 1 to the output buffer when the operation is
complete. The *OPC command sets the OPC bit (bit 0) in the Standard Event
register when the operation is complete.
Immediate triggering
– To select the immediate trigger source, send the following command.
–When the IMMediate is selected as a trigger source, an INITiate command
immediately transfers the VOLT:TRIG or
CURR:TRIG value to VOLT or CURR
value. Any delay is ignored.
