102 Digitizer Command Reference
*ESR? returns the value of the Standard Event Status Register. The register is then
cleared (all bits 0).
•
Executable when initiated: Yes
•
Coupled command: No
•
Reset (*RST) condition: none
•
Power-On condition: register is cleared
*IDN? returns identification information for the HP E1563A and E1564A Digitizers.
The response consists of four fields:
HEWLETT-PACKARD, E1563A, 0, A.01.00
HEWLETT-PACKARD, E1564A, 0, A.01.00
The first two fields identify this instrument as model number HP E1563A (or HP
E1564A) manufactured by Hewlett-Packard. The third field is 0 since the serial
number of the digitizer is unknown to the firmware. The last field indicates the
revision level of the firmware. The revision level shown above is an example and
the actual response you receive will likely be different than the example.

*OPC causes the HP E1563A and E1564A Digitizers to wait for all pending
operations to complete after which the Operation Complete bit (bit 0) in the Standard
Event Status Register is set. The *OPC suspends any other activity on the bus until
the digitizer completes all commands sent to it prior to the *OPC command.
•
The INIT command is considered complete when the measurement is started.
*OPC will not suspend activity once INIT is processed and measurements start
but the instrument may not be finished taking all readings initiated.
