Command: *IDN?
Description: Identification query.
Parameters: None
Response: FLUKE, <model>, <serial-number>, <versions>
<model> = 2640A, 2645A
<serial-number> = 0
<versions> = MMx.x MBx.x F/PAx.x ABx.x D0x.0x LMxx.xx
MM is for outguard main software
MB is for outguard boot monitor software
FA is for 2645A inguard (A/D) main software
PA is for 2640A inguard (A/D) main software
BAis for inguard boot software
D is for display microprocessor software
LM is for FPGA logic
Restrictions: None
Notes: The <serial-number> field is always zero. The instrument could store the serial
number in flash, and let it be set once from the RS-232 interface. But if a replacement
board were ever sent to a customer, it would not have the serial number.
Command: *OPC?
Description: Operation complete query. *OPC? causes the instrument to output an
ASCII “1.”
Parameters: None
Response: <state> = 1
Restrictions: None
Notes: *OPC? is used in conjunction with a non-query command to get a response from
the instrument when the non-query command is finished executing. For example,
sending “CAL 1; *OPC?” will get the “1” response when the instrument is ready to
execute calibration procedure 1.
