*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
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.
