GENERAL - This is a Safety Class I instrument (provided with
terminal for protective earthing).
OPERATION - 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 in-
strument’s external markings which are described under
"Safety Symbols."
•Servicing instructions are for use by service-trained per-
sonnel. To avoid dangerous electric shock, do not perform
any servicing unless qualified to do so.
•BEFORE SWITCHING ON THE INSTRUMENT, the protec-
tive 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 pro-
vided 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.
•If this instrument is to be energized via an auto-trans-
former (for voltage reduction) make sure the common ter-
minal is connected to the earth terminal of the power
source.
•Any interruption of the protective (grounding) conductor
(inside or outside the instrument) or disconnecting the pro-
tective earth terminal will cause a potential shock hazard
that could result in personal injury.
•Whenever it is likely that the protection hasbeen im-
paired, the instrument must be made inoperative and be
secured against any unintended operation.
•Only fuses with the required rated current, voltage, and
specified type (normal blow, time delay, etc.) should be
used. Do not use repaired fusesor short circuited fuse-
holders. To do so could cause a shock or fire hazard.
•Do not operate the instrument in the presence of flamma-
ble gasses or fumes. Operation of any electrical instru-
ment in such an environment constitutesa definite safety
hazard.
•Do not install substitute parts or perform any unauthorized
modification to the instrument.
•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 con-
tacted, result in personal injury.
•Any adjustment, maintenance, and repair of the opened in-
strument under voltage should be avoided asmuch as
possible, and when inevitable, should be carried out only
by a skilled person who is aware of the hazard involved.
•Capacitorsinside the instrument may still be charged
even if theinstrument hasbeen disconnected from its
source of supply.
SAFETY SYMBOLS
Instruction manual symbol. The product will be
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.
Earth terminal (sometimesused in manual to in-
dicate circuit common connected to grounded
chassis).
The WARNING sign denotes a hazard. It
calls attention to a procedure, practice,
or the like, which, if not correctly per-
formed or adhered to, could result in personal injury. Do not
proceed beyond a WARNING sign until the indicated condi-
tions are fully understood and met.
The CAUTION sign denotes a hazard. It
calls attention to an operating procedure,
practice, or the like, which, if not cor-
rectly performed or adhered to, could result in damage to or
destruction of part or all of the product. Do not proceed be-
yond a CAUTION sign until the indicated conditions are fully
understood or met.

MEASUREMENT AIDS
Time Markers:
Two vertical markers, Xand O, are provided for measurements of time and
voltage. Capabilities are: measure voltage at point where Xand O markers
cross each analog waveform; measure time from trigger to X, trigger to O, and
Xto O; automatic marker placement by specifying percentage of edge, edge
number, and rising or falling edge type; run until Xto O > than, < than, in
range, and not in range provides selective event search; X to O statistics (mean,
max, and min) provide analysis of time interval deviation.
Automatic Search:
Searches for a percentage or an absolute voltage level at a positive or negative
edge, count adjustable from 1 to 100.
Auto Search Statistics:
Mean, maximum, and minimum values for elapsed time from Xto O markers for
multiple runs. Number of valid runs and total number of runs available.
Automatic Measurements:
The following pulse parameter measurements can be performed automatically:
Frequency Rise time + pulse width
Period Fall time −pulse width
V p-p Preshoot V amplitude*
Overshoot
(*gives difference between top and base
voltages; only available over bus)
Grid:
Graticules can be displayed in backround of waveform.
Voltage Markers:
Two horizontal markers, Aand B, are provided for voltage measurements.
These markers can each be placed on any acquisition channel trace. A delta
voltage display provides delta Vbetween markers on the same channel or
between two channels.

SECTION II
Installation
2-1. Introduction
This section explains how to initially inspect the
HP 16532A Oscilloscope Module, then how to
prepare it for use, storage, and shipment. 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 contents 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
Supplied" paragraph located in Section I.
Procedures for checking electrical performance
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 sales office.
If the shipping container is damaged, or the
cushioning material shows signs of stress, notify
the carrier as well as the Hewlett-Packard sales
office. Keep the shipping material so the carrier
can inspect 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
Read the Safety Considerations in the front of
this manual and in Section Ibefore installing
or operating this module.
2-4. Power Requirements
All power supplies required for operating the
HP 16532A Oscilloscope Module are supplied to
the module through the backplane connector in
the mainframe.
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 customer to comply with these safety
requirements.
2-6. Module Installation
Do not install, remove, or replace the module
in the instrument unless the instrument power
is turned off.
The HP 16532A Oscilloscope Module will take up
one slot in the card cage. For every additional
HP 16532A Oscilloscope Module you install, you
will need an additional slot. They may be installed
in any slot and in any order. The installation
procedure for the module is continued,
step-by-step, on the next page.

Module Installation (cont.)
The effects of ELECTROSTATIC DISCHARGEcan damage electronic compo-
nents. Use grounded wrist straps and mats when you are performing any kind of
service to this module.
Installation Considerations
•The HP 16532A Oscilloscope Modules can be installed in any available card slot.
•For multiple modules connected as one unit, the master card must be placed in the slot above the
expander cards. The master card and expander cards must be in adjoining slots.
•Cards or filler panels below the empty slots intended for module installation do not have to be re-
moved to install a module above them.
Procedure:
1. Turn instrument power switch off, unplug power cord and disconnect any input connections.
2. Starting from the top, loosen the thumb screws on the filler panels and cards.
3. Starting from the top, begin pulling out the cards and filler panels halfway. See figure 2-1.
