Standard Event Status Register Query
*ESR?
Queries and clears the standard event status event register. (This is
a destructive read.) The value returned reflects the current state
(0/1) of all the bits in the register.
Range:
Integer, 0 to 255
Example:
*ESR? returns a 1 if there is either a query or command error,
otherwise it returns a zero.
Identification Query
*IDN?
Returns an instrument identification information string. The string
will contain the model number, serial number and firmware
revision. The response is organized into four fields separated by
commas. The field definitions are manufacturer, model, serial
number and software version.
Example:
*IDN? returns instrument information, such as:
Keysight Technologies, N9320B, 45310116, A.01.02
Key access:
Preset/
System
Operation Complete Query
*OPC
*OPC?
Sets bit 0 in the standard event status register to "1" when all
pending operations have finished.
The query stops any 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.
Returns a "1" if the last processing is complete. Use this query
when there's a need to monitor the command execution status,
such as a sweep execution.
