*IDN?
*IDN? Identity. Returns the device identity. The response consists of the following
four fields (fields are separated by commas):
•
Manufacturer
•
Model Number
•
Serial Number (returns 0 if not available)
•
Driver Revision (returns 0 if not available)
*IDN? returns the following response strings depending on model and options:
HEWLETT-PACKARD,E1422A,<serial number>,<revision number>
•
The data type for this returned value is string.
Note
The revision will vary with the revision of the driver software installed in the system.
This is the only indication of which version of the driver is installed.
*LMC?
*LMC? Learn Macros query. Returns a quoted string name for each currently defined
macro. If more than one macro is defined, the strings are separated by commas (,). If
no macro is defined, *LMC? returns a null string.
*OPC
*OPC Operation Complete. Causes an instrument to set bit 0 (Operation Complete
Message) in the Standard Event Status Register when all pending operations invoked
by SCPI commands have been completed. By enabling this bit to be reflected in the
Status Byte Register (*ESE 1 command), synchronization between the instrument
and an external computer or between multiple instruments can be ensured.
Note
Do not use *OPC to determine when the CAL:SETUP or CAL:TARE commands
have completed. Instead, use their query forms CAL:SETUP? or CAL:TARE?.
