Chapter 1
General Information
Introduction
This manual contains information required to test, troubleshoot, and repair
the HP E1418A 8/16 Channel D/A Converter Module. See the HP E1418A
User’s Manual for additional module information. Figure 1-1 shows the
HP E1418A module.
Safety Considerations
This product is a Safety Class I instrument that is provided with a protective
earth terminal when installed in the mainframe. The instrument, mainframe,
and all related documentation should be reviewed for familiarization with
safety markings and instructions before operation or service.
Refer to the WARNINGS page (page 6) in this manual for a summary of
safety information. Safety information for preventive maintenance, testing,
adjusting, and service follows and is also found throughout this manual.

Chapter 1 General Information 9

Warnings and
Cautions This section contains WARNINGS which must be followed for your
protection and CAUTIONS which must be followed to avoid damage
to the equipment when performing instrument maintenance or repair.
WARNING SERVICE-TRAINED PERSONNEL ONLY. The information in this
manual is for service-trained personnel who are familiar with
electronic circuitry and are aware of the hazards involved. To
avoid personal injury or damage to the instrument, do not
perform procedures in this manual or do any servicing unless
you are qualified to do so.
CHECK MAINFRAME POWER SETTINGS. Before applying
power, verify that the mainframe setting matches the line
voltage and that the correct fuse is installed. An uninterruptible
safety earth ground must be provided from the main power
source to the supplied power cord set.
GROUNDING REQUIREMENTS. Interruption of the protective
(grounding) conductor (inside or outside the mainframe) or
disconnecting the protective earth terminal will cause a
potential shock hazard that could result in personal injury.
(Grounding one conductor of a two-conductor outlet is not
sufficient protection.)
IMPAIRED PROTECTION. Whenever it is likely that instrument
protection has been impaired, the mainframe must be made
inoperative and be secured against any unintended operation.
REMOVE POWER IF POSSIBLE. Some procedures in this
manual may be performed with power supplied to the
mainframe while protective covers are removed. Energy
available at many points may, if contacted, result in personal
injury. (If maintenance can be performed without power applied,
the power should be removed.)
10 General Information Chapter 1

WARNING USING AUTOTRANSFORMERS. If the mainframe is to be
energized via an autotransformer (for voltage reduction) make
sure the common terminal is connected to neutral (that is, the
grounded side of the main’s supply).
CAPACITOR VOLTAGES. Capacitors inside the mainframe may
remain charged even when the mainframe has been
disconnected from its source of supply.
USE PROPER FUSES. For continued protection against fire
hazard, replace the line fuses only with fuses of the same
current rating and type (such as normal blow, time delay, etc.).
Do not use repaired fuses or short-circuited fuseholders.
SHOCK HAZARD. Only service-trained personnel who are
aware of the hazards involved should install, remove, or
configure the module. Before you remove any installed module,
disconnect AC power from the mainframe and from other
modules that may be connected to the module.
CHANNEL WIRING INSULATION. All channels that have a
common connection must be insulated so that the user is
protected from electrical shock. This means wiring for all
channels must be insulated as though each channel carries the
voltage of the highest voltage channel.
CAUTION MAXIMUM VOLTAGE. The maximum voltage that can be applied to
any channel is 42 V Peak/42 Vdc. The maximum voltage from any
channel to ground is 42 V Peak/42 Vdc.
STATIC ELECTRICITY. Static electricity is a major cause of
component failure. To prevent damage to the electrical components in
the module, observe anti-static techniques whenever working on the
device.
PARTS REMOVAL. This module uses a surface mount printed circuit
assembly. Special soldering equipment is required for parts removal or
replacement. Use of standard soldering equipment will cause damage
to the printed circuit board and is not covered under warranty.
Chapter 1 General Information 11

Module Description
The HP E1418A is an 8 or 16 channel digital-to-analog converter module
for use in a VXIbus C-size mainframe. The module is a register based
device. The module can be programmed via direct register access or, with
the appropriate driver, by high level commands. This manual describes
programming the module using SCPI (Standard Commands for
Programmable Instruments) and the SCPI driver.
Each HP E1418A module is a unique instrument having its own output
buffer and error queue. Multiple modules can not be combined into a
single instrument.
Each channel can be configured to either voltage or current output mode.
When configured for voltage output, voltages in the range of -16.0 V to
+16.0 V can be set. When configured for current output, current in the
range of -0.02 to + 0.02 Amps can be set. The channel output mode can
be programmatically set, or, can be forced to either voltage or current by
mechanical jumpers on the terminal block.
Each output channel is individually configurable to be either an isolated
output or a non-isolated output. Channel configuration to isolated or
non-isolated is made by individual plug-on modules for each channel.
Module
Specifications Specifications are listed in Appendix A of this manual and in the
HP E1418A User’s Manual. These specifications are the performance
standards or limits against which the module may be tested.
Module Serial
Numbers Devices covered by this manual are identified by a serial number prefix
listed on the title page. Hewlett-Packard uses a two-part serial number in
the form USXXXXYYYYY, where US is the country of origin, XXXX is
the serial prefix, and YYYYY is the serial suffix. The serial number prefix
identifies a series of identical instruments. The serial number suffix is
assigned sequentially to each instrument. The serial number plate is located
on the right-hand shield near the backplane connectors.

Introduction
This chapter contains the following topics:
•Initial Inspection
•Preparation for Use
•Environment
•Shipping Guidelines
Initial Inspection
Inspect the shipping container for damage. If the shipping container or
cushioning material is damaged, keep the container until the shipment
contents have been checked and the module has been checked mechanically
and electrically. Chapter 4 of this manual gives procedures to check the
electrical performance.
WARNING To avoid possible hazardous electrical shock, do not perform
electrical tests if there are signs of shipping damage to any
portion of the outer enclosure (covers, panels, etc.).
If the contents are incomplete, if there is mechanical damage or defect, or if
the module does not pass the electrical performance tests, notify your
nearest Hewlett-Packard Sales and Service Office. If the shipping container
is damaged or the cushioning material shows signs of stress, notify the
carrier as well as Hewlett-Packard. Keep the shipping materials for the
carrier’s inspection.
Chapter 2 Installation 15

Preparation for Use
Chapter 1 of the HP E1418A User’s Manual contains complete instructions
for installing the module in a mainframe and installing a terminal module.
Refer to the mainframe user’s manual, command module user’s manual, and
the Installing Device Drivers installation note to prepare the mainframe.
Prepare the Module Verify or set the module’s logical address. Refer to the HP E1418A User’s
Manual for instructions. In this manual the factory default logical address
of 72 is used.
To prepare the module for the adjustment procedures in Chapter 5, set or
verify the position of the CAL Secure Enable Jumper before installing the
module in the mainframe. (The jumper is factory set to CAL.) Figure 5-2 on
page 62 shows this jumper.
Prepare the
Terminal Module The procedures in this manual show the screw-type terminal module. To
prepare this terminal module, you will need to set the jumpers and make
connections. If you are using other types of terminal modules, consult the
HP E1418A User’s Manual for proper connections.
Terminal Module
Jumpers The screw-type terminal module contains jumpers that control how the
HP E1418A operates. To prepare the module for the Verification Tests in
Chapter 4 and Adjustments in Chapter 5, the terminal module jumpers must
be set to allow the module to be programmed from the backplane. The
HP E1418A will operate without any jumpers installed. Figure 2-1 shows
the jumper locations and example settings.
There are two jumpers for each channel; a P/J jumper and a V/I jumper.
The two jumpers work together.
The P/J jumper sets the channel output mode to be either Program
Selectable or Jumper Selectable. When the jumper is in the program
selectable position, the channel output mode can be set via programming
commands. The program selectable position is recommended for the
Verification Tests and Adjustment procedures in this manual. In the jumper
selectable position, the channel output mode is set via the V/I jumper.
The V/I jumper sets the channel output mode to either voltage or current
when the P/J jumper is set to the Jumper Selectable position. When the P/J
jumper is set to Program Selectable, this jumper has no effect.
16 Installation Chapter 2

Note With no jumpers installed, the module will be in the Program Selectable
output mode.
•If you are using a terminal module dedicated to testing the HP E1418A,
you can remove all the jumpers or put the jumpers in the storage
position.
•If you are using the end-user’s terminal module, record the positions of
the jumpers. Set the P/J jumpers to the programmable position. Before
returning the module to use, restore the P/J jumpers to their original
position.
Terminal Module
Connections The Verification Tests require four-wire connections at each channel. The
Adjustment procedures can be performed using a single connections at the
CAL terminals. Additional connection information is given in the
procedures in Chapters 4 and 5 of this manual.
Prepare the
Command Module All verification and adjustment procedures in this manual use SCPI
(Standard Commands for Programmable Instruments). Prepare the
command module by downloading the SCPI driver named “E1418".
Downloading instructions are given in the Installing Device Drivers
installation note.

Environment
The recommended operating altitude for the module is 2000 m (6000 ft) or less.
The recommended operating environment for the module is:
Environment Temperature Humidity
Operating 0
oC to + 55 oC <65% relative (0 oC to + 40 oC)
non condensing
Storage and
Shipment – 40 oC to + 75 oC <65% relative (0 oC to + 40 oC)
non condensing
Shipping Guidelines
If you need to return the HP E1418A to Hewlett-Packard, first remove any
terminal modules before packaging for shipment. Attach a tag to the module
identifying the owner and indicating the service or repair required. Mark the
shipping container “FRAGILE”. If you are exchanging a module, read
Assembly Exchange beginning on page 85.
In any correspondence, refer to the module by model number and full serial
number.
Hewlett-Packard recommends using shipping containers and materials
identical to those used by the factory. These materials are available through
Hewlett-Packard Sales and Service Offices.
If you use commercially available shipping materials, place the module in
an anti-static bag and wrap the module in heavy paper or plastic. Use a
strong shipping container. A double wall carton of 2400 Pa (350 psi) test
material is adequate.
Use enough shock-absorbing material (layer at least 75 mm to 110 mm,
3 in to 4 in) around the module to provide firm cushion and to prevent
movement in the container. Protect the front panel with cardboard. Seal the
container securely and mark the container “FRAGILE”.

Operating Information
Introduction
This chapter provides operating information, preventive maintenance
instructions, and operators checks.
Operation
The HP E1418A User’s Guide is your reference for module operation.
The User’s Guide contains information about module setup, application
examples, and a complete SCPI command reference.
Querying Module
Identification and
Configuration
This example will query the module for the identification string and
determine the module configuration.
The module identification is obtained using the IEEE-488 Command
Command *IDN?.
/* Send query to the module*/
*IDN?
/* Enter a string*/
The string returned will be similar to one of the following:
HEWLETT-PACKARD,E1418A_8CH,xxxxxxxxxx,A.01.00
or
HEWLETT-PACKARD,E1418A_16CH,xxxxxxxxxx,A.01.00
The xxxxxxxxxx portion of the response string is the module serial number.
The number of channels in the module (8 or 16) is indicated by the
E1418A_8CH or E1418A_16CH portion of the returned string.
