SECTION III
OPERATION
INTRODUCTION
This section explains how to operate the Hewlett-
Packard Model 11713A. Included in this section
are the descriptions of front and rear panel con¬
trols, connectors and indicators, operator's
checks, operating instructions, and operator main¬
tenance. The last part of this section contains des¬
criptions and diagrams explaining available rear
panel connections for rf and coaxial switches,
attenuators, and relays.
Local operating instructions and remote opera¬
tion with the Hewlett-Packard Interface Bus (HP-
IB) are explained below,

This section contains information on the front
panel featu^s and the operator's check. When the
IJnveFLINE switch is set tol^N^t^^ Driver~comes
up in LOCAL and all numbered front panel
switches are illuminated..
WARNINGS
Before the instrument is switched on, all
protective earth terminals, extension
cords, auto-transformers, and devices
connected to it should be connected to a
protective earth grounded socket. Any
interruption of the protective earth
grounding will cause a potential shock
hazard that could result in personal
injury.
Only fuses with the required rated cur¬
rent and specified type should be used.
Do not use repaired fuses or short cir¬
cuited fuseholders. To do so could cause
a shock or fire hazard.
Panel Features
The front and rear panel features are given in
Figures 3-1 and 3-2. These include explanations of
the controls, connectors and indicators.
Operator's Check
The operator's check is described in Table 3-1. This
check provides the initial Driver turn-on proce¬
dure and local operation.
REMOTE OPERATION
The Driver can be operated through the Hewlett-
Packard Interface Bus (HP-IB). Bus compatibil¬
ity, operator's interface checks, programming,
and data format are described in the following
paragraphs.
Remote-only functions and all front panel func¬
tions- (except the LINE switch) are programmable
through the HP-IB.

can function with each of the applicable bus mes¬
sages. The bus messages are described in Table
3-3.
For more information about HP-IB, refer to IEEE
Std 488, ANSI Std MCl.l, the Hewlett-Packard
Electronic Systems and Instruments catalog, and
the booklet, "Tutorial Description of the Hewlett-
Packard Interface Bus" (HP part number
5952-0156).
HP-IB Compatibility
The Driver's complete bus compatibility (as de¬
fined by IEEE Standard 488, and the identical
ANSI Standard MCl.l) is described below Table
3-3. Table 3-3 also summarizes, in the left-hand
column, the Driver's HP-IB capabilities in terms
of the twelve bus messages. Foremost among
these messages is the Data message. Data mes¬
sages contain the program codes that set the
Driver's outputs.
Remote Mode
Remote Capability. The Driver accepts commands
from the bus in the remote mode. In remote, its
front panel controls are disabled (except for the
