SAFETY CONSIDERATIONS
GENERAL -This
Is
a Safety Class I Instrument (provided
with terminal for protective earthing).
OPERATIO~
-BEFORE APPLYING POWER verify that the
power transformer primary.
Is
matched to the available line
voltage, the correct fuse
Is
Installed, and Safety Precautions
are taken
(see
the following warnings). In addition, note the
Instrument's external markings which are described under
"Safety Symbols."
IWARNING I
o Servicing Instructions are for use by service-trained
personnel. To avoid dangerous electric shock, do
not
perform any servicing unless qualified to do
so.
o BEFORE SWITCHING
ON
THE INSTRUMENT, the
protective earth terminal of the Instrument must
be
connected to the protective conductor
of
the (mains)
powercord. The mains plug shall only
be
Inserted
In
a
socket outlet provided with a protective earth contact. The
protective action must not be negated by the use of
an
extension cord (power cable) without a protective
conductor (grounding). Grounding one conductor of a two-
conductor outlet
Is
not sufficient protection.
o If this Instrument
Is
to
be
energized
via
an
auto-transformer (for voltage reduction) make sure the
common terminal is connected to the earth terminal of the
power source.
o Any Interruption of the protective (grounding) conductor
(Inside or outside the Instrument)
or
disconnecting the
protective earth terminal will cause a potential shock
hazard that could result In personal Injury.
o Whenever It
Is
likely that the protection has been Impaired,
the Instrument must
be
made Inoperative and be secured
against any unintended operation.
o Only fuses with the required rated current, voltage, and
specified type (normal blow, time delay, etc.) should be
used. Do not use repaired fuses or short circuited
fuseholders. To do so could cause a shock or fire hazard.
o Do not operate the Instrument in the presence of flammable
gasses or fumes. Operation of any electrical Instrument
In
such
an
environment constitutes a definite safety hazard.
o
Do
not Install substitute parts or perform any unauthorized
modification to the Instrument.
o Adjustments described
In
the manual are performed with
power supplied to the Instrument while protective covers
are removed. Energy available at many pOints may, If
contacted, result In personal Injury.
o Any adjustment, maintenance, and repair
of
the opened
Instrument under voltage should be avoided
as
much as
possible, and when Inevitable, should
be
carried
out
only
by
a skilled person who
Is
aware of the hazard Involved.
o CapaCitors Inside the Instrument may stili be charged even
If the Instrument has been disconnected from Its source
of
supply.
SAFETY SYMBOLS
Instruction manual symbol. The product will
be
ill marked with this symbol when It
Is
necessary for
the user to refer to the Instruction manual In order
to protect against damage to the product.
~
Indicates hazardous voltages.
-L
Earth terminal (sometimes used In manual to
indicate circuit common connected
to
grounded
chassis).
IWARNING I The WARNING sign denotes a hazard. It
calls attention to a procedure, practice,
or
the like, which, If
not
correctly
performed or adhered to, could result In personal Injury. Do
not proceed beyond a WARNING sign until the Indicated
conditions are fully understood and met.
I
':::~:::::~:~~;:~!
The CAUTION sign denotes a hazard. It
~i
calls attention to an operating procedure,
practice, or the like, which, If
not
. correctly performed or adhered to, could result
In
damage to
or destruction
of
part or
all
of the product. Do not proceed
beyond a CAUTION sign until the Indicated conditions are
fully understood
or
met.

2-1. INTRODUCTION
This section explains, how to initially inspect
the
HP
16520/21A Pattern Generator Module,
how to prepare it for use, storage and ship-
ment. Also included
are
procedures for module
installation.
2-2. INITIAL INSPECTION
Inspect the shipping container for damage. If
the shipping container or cushioning material
is
damaged, it should
be
kept until the con-
tents of the shipment have been checked for
completeness and the module
has
been
checked mechanically and electrically. The
contents of the shipment should
be
as
listed
in
the "ACCESSORIES SUPPLIES" paragraph lo-
cated in Section
I.
Procedures for checking electrical perfor-
mance
are
in Section III. If the contents of the
container
are
incomplete, there
is
mechanical
damage or defect, or the instrument does not
pass the performance tests, notify the nearest
Hewlett-Packard office.
If the shipping container
is
damaged, or the
cushioning material shows signs of stress,
notify the carrier
as
well
as
the
Hewlett-Packard office.
Keep
the shipping
material
so
the carrier can inspection it. The
Hewlett-Packard office will arrange for repair
or replacement at Hewlett-Packard's option
without waiting for claim settlement.
2-3. PREPARATION FOR USE
I
WARNING
I
Read the Safety Considerations in the
front
of
this manual and in Section I
before installing or operating this
module.
HP
16520/21A - Installation
SECTION
·11
INSTALLATION
2-4. POWER REQUIREMENTS
All
power supplies required for operating the
HP
16520/21A Pattern Generator Module are
supplied to the module through the backplane
connenctor.
2-5. SAFETY REQUIREMENTS
Specific warnings, cautions, and instructions
are
placed wherever applicable throughout the
manual. These must
be
observed during all
phases
of
operation, service, and repair of the
module. Failure to comply with them violates
safety standards of deSign, manufacture, and
intended use of this module. Hewlett-Packard
assumes no liability for the failure of the cus-
tomer to comply with these safety
requirements.
2-6. PROBE CABLE INSTALLATION
The
HP
16520/21A Pattern Generator Module
comes with probe cables installed by the fac-
tory. If a cable
is
to
be
switched between TTL
and
ECl,
refer to "PROBE CABLE
REPLACEMENT" in Section
VI
of this manual.
2-7. INSTALLATION
Do
not install, remove or replace the
module in the instrument unless the in-
strument power
is
turned off.
The HP16520A Pattern Generator Card will
take up one slot in the card cage. For every
HP
16521
A Expansion Card you connect to
the
HP
16520A Pattern Generator Card you
will need
an
additional slot. A maximum of
four expansion cards may
be
connected to the
HP
16520A Pattern Generator Card.
Installation procedures for the module and ad-
ditional expansion cards
are
shown
step-by-step
in
paragraphs 2-6 and 2-7.
