2.1 INTRODUCTION
Table 2.1 summarises the result formats applicable to 3595 Series IMP types 1A, 1B, 1C, 1D, 1E, 2A and 2B.
For IMP types 3595 1H and 1J, the same formats apply. However, depending on the result mode
selected, the results may be time-tagged.
The three result modes of IMP types 3595 1H and 1J are:
•
Real-time –exactly the same format as for all other IMP types.
•
Time-tagged –each scan data block, or single measurement result, has a bookmark and time-tag appended.
•
Historical – allows the IMP to pass historical time-tagged results back to the Host PC.
The formats of the bytes appended in the time-tagged and historical modes are described in Sections 2.5
and 2.6.
The error messages that may be returned by any IMP are listed in Section 2.7, together with their
meanings.
