Syntax
*CLS
Function
When multiple commands are issued on
the same line, after the command in front
of the *OPC command finishes, Standard
Event Status Register (SESR) bit0 is set
to 1.
Function
Returns "1" as the response message
instead of setting bit0 (the OPC bit) of
the Standard Event Status Register
(SESR) to 1.
Note
With this query, if any error occurs, no
response message is produced.
Function
Forces the unit to wait until all previous
commands have executed.
Note
All 7075-specific commands are
sequential type, so the WAI command
has no effect. However, it is included for
compliance with the IEEE-488.2 1987
standard.
Function
Clears all event registers corresponding to
each bit of the status byte register.
Note
This has no effect upon the output queue,
the various enable registers, or bit 4 (the
MAV bit) of the status byte register.
*OPC
After all action has been completed during execution, performs an SRQ request.
*OPC?
Queries whether all action has been completed.
*
WAI (GP-IB only)
Waits until sampling is fully completed.
*CLS
Clears the status byte register and the event registers.
