Where:
The data contained in the response consists of four comma-
separated fields, the last two of which are instrument-depend-
ent. The data element type is defined in the IEEE 488.2 standard
specification.
A single query sent as a terminated program message will elicit
a single response terminated by:
nl = newline with EOI
If multiple queries are sent as a string of program message units
(separated by semi-colons with the string followed by a
permitted terminator), then the responses will be returned as a
similar string whose sequence corresponds to the sequence of
the program queries. The final response in the string will be
followed by the terminator:
nl = newline with EOI
Response Decode:
The data contained in the four fields is organized as follows:
•
First field
-
manufacturer
•
Second field -
model
•
Third field
-
serial number
•
Fourth field
-
firmware level (will possibly vary from
one instrument to another).
Execution Errors:
None.
Power On and Reset Conditions
Not applicable.
