HEWLETT-PACKARD INTERFACE BUS (HP-IB)
Corn pati bil ity
The Modulation Analyzer's capabilities are defmed by the following interface functions: SH1, AH1,
T5, TEO, L3, LEO, SR1, RL1, PPO, DC1,
DT1,
CO. The Modulation Analyzer interfaces with the bus
via open-collector
TTL
circuitry. An explanation of the compatibility code may be found in
IEEE
Standard 488- 1978, IEEE Standard and Digital Interface for Programmable Instrumentation or
the identical ANSI Standard MC 1.1.
For more detailed informationrelating to programmable control of the Modulation Analyzer, refer t o
Remote Operation, Hewlett-Packard Interface Bus in Section 3 of this Operating Information manual.
Selecting the HP-IB Address
The HP-IB address switches are located within the Modulation Analyzer. The switches represent a
five-bit binary number. This number represents the talk and listen address characters which the
controller must generate. In addition, two more switches allow the Modulation Analyzer to be set t o
talk only or t o listen only. A table in Section 2 shows all HP-IB talk and listen addresses. Refer to
HP-IB Address Selection in Section
2 of this
Operation and Calibration manual.

PUT, SENSOR input, MODULATION OUTPUT/AUDIO INPUT, and AMYFM and RF POWER
CALIBRATION OUTPUTS.
Option
002. This option provides a high-stability
(1
x
10-g/day) internal reference oscillator in
place of the standard reference oscillator. In addition, a 10 MHz time base output
