IEEE 488.2 Common Commands
Common Command Descriptions
*IDN?
(Identification
Query)
The *IDN? query causes a device to send its identification information over the
bus. The Test Set responds to the *IDN? command by placing its identification
information, in ASCII format, into the Output Queue. The response data is
obtained by reading the Output Queue into a string variable of length 72. The
response data is organized into four fields separated by commas. The field
definitions are described
in
Table 15.
NOTE: The Serial Number format can take one of two forms:
AAXXXXXXXX
or
XXXXAXXXXX
A = alpha character
X = numeric character
The form returned will depend upon the manufacturing date of the Test Set being queried.
Example program
10 DIM A$[72]
20 OUTPUT 714;"*IDN?"
30 ENTER 714;A$
40 PRINT A$
50 END
Example response
