Device Talking Syntax
The talking syntax of IEEE 488.2 is designed to be more precise than the
listening syntax. This allows the programmer to write routines which can
easily interpret and use the data the instrument is sending. One of the
implications of thii is the absence of
white space in the talking
formats. The instrument will not pad messages which are being sent to the
controller with spaces.
response message
. This element serves as a complete response from
the instrument. It is the result of the instrument executing and buffering
the results from a complete c program message . The complete
response message should be read before sending another c program
message to the instrument.
Figure A-20. response message
response message unit
. This element serves as the container of
individual pieces of a response. Typically a query message unit
will
generate
one
response message unit , although a query message
unit may generate multiple response message unit s.
response header
. The response header , when returned,
indicates what the response data represents.
