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
to
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
to
talk only
or
to
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.
