3-151. PROGRAMMING
3-152. Introduction
3-153. The 5335A Universal Counter is fully compatible with the Hewlett-Packard Interface bus
(HP-IB). The bus capability is installed as standard equipment and allows the counter to respond
to remote control instructions and output measurement results via the HP-IB. At the simplest
level, the 5335A can output data to other devices such as the 5150A Thermal Printer or the 59303A
Digita!-to-Anaiog Converter. In more sophisticated systems, a computing controller or other
controllers can remotely program the 5335A to perform a specific type of measurement, trigger
the measurement, and read the results.
NOTE
HP-IB is Hewlett-Packard's implementation of IEEE Std. 488-1978,
“Standard Digital Interface for Programmable Instrumentation
