1-0 General Information

General Information
1-1. Introduction
The HP E1426A Service Manual contains all the information
required
to test, adjust, troubleshoot, and repair the Hewlett-Packard
Model E1426A C Size
VXI 500 MHz Digitizing Oscilloscope. Figure 1-
1 shows the HP E1426A Oscilloscope, along with all of the externally
supplied accessories. Additional copies of the HP E1426A User's
Manual and Service Manual can
be ordered separately through your
nearest Hewlett-Packard ofice.
1-2. Specifications
Instrument specifications are listed in Appendix A of the HP
Considerations
E1426A User's Manual. These specifications are the performance
standards or limits against which the instrument may be tested.
1-3. Safety
This product is a Safety Class I instrument, that is, one provided with
Considerations
a protective earth terminal when installed in the mainframe. The
mainframe, oscilloscope, and all related documentation should be
reviewed for familiarization with safety markings and instructions
before operation or service. Refer to the Safety Considerations page
found atthe beginning of this manual for a summary of the safety
information. Safety information for preventive maintenance,
testing, adjusting, or service is found in appropriate places throughout
this manual.
1-4. Manual Updates Manual Updates provide information necessary to update the manual.
The Manual Update is identified by the manual print date and part
number, both of which appear on the manual title page.
1-5. Description The Oscilloscope module is a general purpose, four channel, 500 MHz
(repetitive bandwidth) oscilloscope, which provides all the versatility
and capability of digitizing oscilloscopes. The Oscilloscope module is
a VXIbus C-Size message-based product, and can operate in a C-Size
VXIbus mainframe using an HP El405 Command Module.
The Oscilloscope module is comprised of a CPU Printed Circuit
Assembly (PCA) (HP P/N E1426-69501) and an Acquisition PCA (HP
P/N E1426-69502).
General Information 1-1

The Acquisition PCA attenuatedamplifies each of the four inputs.
The conditioned input signal is then routed
to a track and hold
circuit. The signal is then multiplexed
to an A/D Converter where it
is changed into a digital word. This digital information is stored for
use
by the CPU PCA. A replica of the conditioned input signal is also
used for triggering. Additional functions include:
Time base circuit provides the timing signals necessary for
data acquisition.
AC calibrator circuit provides signals for probe compensation,
trigger event, and calibration.
DC calibrator circuit provides a calibration signal.
The CPU PCA contains the control and interface circuits necessary to
direct oscilloscope operations. Control information (COMP or
SCPI)
is received from the mainframe controller, and the necessary
instructions are sent
to the Acquisition PCA to perform the specific
task. When the digital waveform information is received from the
Acquisition PCA, all the user requested parameters are measured and
routed to the mainframe. Additional functions include:
n'L and ECL trigger signals from the mainframe are routed
to the Acquisition PCA to perform "external trigger"
functions.
'M'L and ECL trigger signals from the oscilloscope are routed
to the mainframe over the backplane trigger bus lines.
Trigger circuit provides a ITLTrigger output signal on the
front panel.
Refer to the HP E1426A User's Manual for additional information on
the HPE1426A Oscilloscope.

1-6. Instruments
Covered by this
Manual
Instruments 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 X)(XXAYYYYY,where
XMM is the
serial prefix, A is the country of origin (A=USA) and
YYYYY is the
serial suffix. The serial number prefix identifies
a series of
identical instruments. The serial number suffix is assigned
sequentially and is unique
to each instrument. If the serial number
prefix of your instrument is greater than the one listed on the title
page, a yellow Manual Update supplement will explain how to adapt
this manual
to your instrument. If the serial number prefix of your
instrument is lower than the one listed on the title page, information
contained in Chapter
7 (Manual Changes) will explain how to adapt
this manual
to your instrument.

Installation
2-1. Introduction
This chapter provides the information needed to install the HP
E1426A Oscilloscope. Included is information pertinent to initial
inspection, preparation for use, environment, storage and shipment.
2-2. Initial Inspection
Warning To avoid hazardous electrical shock, do not perform electrical
tests when there
are signs of shipping damage to any portion
of the outer enclosure (covers, panels, etch
Inspect the shipping container for damage. If the shipping container
or cushioning material is damaged, it should be kept until the
contents of the shipment have been checked for completeness and the
instrument has been checked mechanically and electrically. The
contents of the shipment should be as shown in Figure
1-1. Procedures
for checking electrical performance are given in Chapter 4. If the
contents are incomplete, if there is mechanical damage or defect, or if
the instrument does not pass the electrical performance test, notify the
nearest Hewlett-Packard ofice. If the shipping container is damaged
or the cushioning material shows signs of stress, notify the carrier as
well asthe Hewlett-Packard ofice. Keep the shipping materials for
the carrier's inspection.
2-3. Preparation Complete instructions for preparing the HP E1426A Oscilloscope for
for Use
use are provided in the HP E1426A User's Manual, the HP E1400B
Mainframe User's Manual, and the HP El405 Command Module
User's Manual. Procedures include:

Module Installation
The operating environment should be within the following
:
limitations
Temperature
........................................... 0 to +55"C
......................... Humidity
65% relative (0to +40°C)
2-5. Storage and
Shipment
2-6. Environment The instrument should be stored in a clean, dry environment. The
following environmental limitations apply to both storage and
shipment:
........................................ Temperature 40to +75OC
......................
Humidity <65%relative (0to +40°C)
2-7. Packaging Preparation for Packaging. Remove any adapters or connectors
before packaging instrument for shipping.
Tagging for Service. If the instrument is being returned to Hewlett-
Packard for service, please complete one of the blue repair tags
located atthe back of this manual and attach it to the instrument.
Original Packaging. Containers and materials identical to those
used in factory packaging are available through Hewlett-Packard
offices. Mark the container "FRAGILE to assure careful handling.
In any correspondence refer to the instrument by model number and
full serial number.
Other Packaging. The following general instructions should be used
for re-packaging with commercially available materials:
a. Wrap the instrument in heavy paper or plastic. (If shipping to
a Hewlett-Packard ofice or service center, complete one of the
blue tags mentioned above and attach it to the instrument.)
b. Use a strong shipping container.
A double-wall carton made
of 2.4 MPa (350 psi) test material is adequate.
c. Use enough shock-absorbing material (75to 100mm layer;
3 to
4 inches) around all sides of the instrument to provide firm
cushion and prevent movement in the container. Protect the
front panel with cardboard.
d. Seal the shipping container securely.
e. Mark the shipping container
"FRAGILE to assure careful
handling.
