GPIB Bus Compatible Interface
- The general purpose interface bus (GPIB) is a stan-
dard bus for parallel control of electronic equipment. The two meter (6.6 foot) cable
supplied connects the Calorimeter unit to a user-supplied GPIB controller. The GPIB
cable meets the requirements of IEEE Standard 488-1978.
Accessory Items
A two meter (6.6 ft) GPIB cable is supplied with the Calorimeter. Other GPIB cables
are available as follows:
Recommended Test
Equipment
Table 1 list equipment recommended for performance testing and maintenance of the
Calorimeter. The critical equipment parameters listed are the minimum specifica-
tions applicable to test and measurement devices other than those listed. Valid Calo-
rimeter tests and measurements are critical and depend largely on the accuracy of
the test and measurement devices used. Refer to Chapter 5 - Maintenance for more
information on testing and calibration.
Electromagnetic
Interference
The Calorimeter has been tested and was found to meet Class A limits as specified in
Part 15J of the FCC requirement for electromagnetic emissions.
