Reading Product Identification ___________________________
This query returns the Receiver identification.
Response
• A sequence of ASCII-encoded bytes:
HEWLETT-PACKARD, 59551A, XXXXYZZZZZ, WWWW – V
where 59551A is the product model number, XXXXYZZZZZ is the product
serial number, and WWWW is the product’s firmware revision date code,
and V is the hardware revision letter.
In the product serial number (XXXXYZZZZZ):
– XXXX is a four-digit prefix that identifies a series of instruments.
– Y identifies the country in which the instrument was manufactured
(e.g., the “A” in 3426A000123 stands for America).
– ZZZZZ is a five-digit suffix that identifies a particular instrument
within a series.
• For example,
HEWLETT-PACKARD, 59551A,3426A00123,3422 – A
This query should be the last query in a terminated program message;
otherwise, error -440 is generated.

Preparatory to installation of new product firmware, the instrument is
switched to the “INSTALL” language, available only on PORT 1.
The “INSTALL” language includes an *IDN? query which returns the revision
identification for the installation firmware. The response format is the same as
described above for the instrument’s “PRIMARY” language, but the
identification code may be different.
