Common IEEE Commands

SYST:SET #NMMMM<state_data>

The following example is a response to *LRN? The actual sizes will vary depending on the instrument state data size.

Example: :SYST:SET #42016<state data>

Where: 4 (the N in the preceding query response example) represents the number of digits to follow

Where: 2016 (the MMMM in the preceding query response example) represents the number of bytes that follow in the <state data>.

The state can be changed by sending this block of data to the instrument after removing the size information:

:SYST:SET <state data>

Operation Complete Command

*OPC

Sets bit 0 in the standard event status register to “1” when pending operations have finished.

The instrument default is to only wait for completion of the internal self-alignment routines. You must set the STATus:OPERation:EVENt resgister if you want to look for the completion of additional processes. See *OPC? below.

Key Type:

There is no equivalent front panel key.

Operation Complete Query

*OPC?

This query stops new commands from being processed until the current processing is complete. Then it returns a “1”, and the program continues. This query can be used to synchronize events of other instruments on the external bus.

The instrument default is to only wait for completion of the internal self-alignment routines. You must set the STATus:OPERation:EVENt resgister if you want to look for the completion of additional processes such as:
