SAFETY CONSIDERATIONS

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 instrument’s external markings which are described under "Safety Symbols."

• Ser vicing instructions are for use by service-trained personnel. To avoid dangerous electric shock, do not perform any servicing unless qua lified to do so.

• 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 e x tension cord (power cable) without a protective conductor (grounding). Gr ou nding one conductor of a two-con duc tor outlet is not sufficie nt protec tion.

• If this instrument is to be e nergized vi a an auto-transformer (for v oltage reduction) make sure the common terminal is connected to the earth terminal of the power source.

• Any interruption of the protective (grounding) conductor (ins i de or outside th e instrument) or disconnecting the protective earth terminal will cause a potential shock hazard that could result in personal injury.

• W henever it is lik ely that the protection has been impaired, the instrument must be made inoperative and be sec ur ed 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 us e repaired fuses or shor t circuited fus eholders. To do so could cause a shock or fire hazard.

• 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 safe ty hazard.

• Do not in stall substitute parts or perfor m any unauthorized modification to the instrument.

• A djustments described in the manual are performed with power supplied to the instrument while protective covers are r e move d. E ne rgy available at many points may, if contacted, result in personal injury.

• A ny 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.

• Capacitors inside the instrument may still be charged even if the ins trument has been disconnected from its source of supply.

SAFETY SYMBOLS

Ins tr uction manual sy mbol. 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.

Indicates hazardous voltages

Earth terminal (sometimes used in manual to indicate 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 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.

The CAUTION sign denotes a hazard. It 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 a ll of the product. D o not proceed beyond a CAUTION sign until the indicated conditions are fully understood or met.

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. T h e contents of the shipment should be as lis te d in the "Accessories Supplie d" par agraph l ocated in Secti on 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 instrume nt does not pass the performance tests, notify the nearest Hewlett-Packard sales office.

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 mainfra me .

2-5. Safety Requirements

Hewlett-Packard assumes no liability for the failure of the customer to comply with these safe ty requirements.

2-6. Module Installation

If the shipping container is damaged, or the cushioning material shows signs of stress, notify the carrier as w e ll a s the Hewlett-P a ckard sa l e s office. Keep the shipping material so the carrie r can inspect it. Th e H e wle tt-P a ckard office will arrange for repair or replacement at Hewlett-Packard’s option without waiting for claim settlement.

2-3. Preparation for Use

Rea d the Safety Considerations in the front of this man u al and in Section I be f or e ins talling or operating this module.

Do not inst all, 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 ev e ry a dditional HP 16532A Oscilloscope Module you install, you will need an a dditional slot. Th e y may be insta lle d in any slot and in any order. The install a tion procedure for the module is continued, step-by-step, on the next page.

Module Insta llation (cont. )

The effects of ELECTR OST ATIC D ISCHARG E can damage electronic components. U se 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 ma s te r card must be placed in the s lot above the

expander cards. The ma s ter card and expander cards must be in adjoining slots.

• Cards or filler panels below the e mpty slots intended for module installation do not have to be re-

moved to install a module above them.

Proced u r e:

1. T urn i ns trume nt power switch off, unplug power cord and disconnect any input connections.

2. Starting from the top, loosen the thumb screws on the fille r pane ls and cards.

3. Starting from the top, begin pulling out the cards and filler panels halfway. See figure 2-1.

4. S lide the oscilloscope module into the card cage approximately halfway.

5. If you hav e more oscilloscope cards to install, slide them into the card cage approximately halfway.

6. F irmly s eat the bottom card into the backplane connector. Keep applying pressure to the center

of the card endplate while tightening the thumb screws finger tight.

7. Repeat step 6 for all cards and filler panels in a bottom-to-top order. See figure 2-2.

8. A ny fille r pane ls tha t a re not used should be kept for future use. Fille r pane ls must be ins t alle d i n all

unused card slots for correct air circulation.

2-7. Operating Environment

Th e operating env ironment is lis te d in table 1-2 of Se ction I of this manu a l. N ote s h ould be made of the non-condensing humidity limitation. Condensa tion within the instrume nt can cause poor oper ation or malfun ct ion . Protect i on should be provided against internal condensation.

The HP 16532A Oscilloscope Module will operate at all specifications within the te mpera ture an d humidity range giv en in table 1-2. H owe ver, reliability is enhanced when operating the module within the following ranges.

• Temperature: + 20 °C to + 35 °C (+ 68 °F to

+ 95 °F)

• Humidity: 20% to 80% non-condensing

2-8. Storage

T h e module m ay be s tor e d or shippe d i n environments within the following limits:

2-9. Packaging

The following general instructions sh ould be us ed for repacking the module with commercially availa ble ma teria ls .

• Wrap the module in antis tatic plastic.

• Use a strong shipping container. A double-

walled carton made of 350-lb test material is adequate.

• Use a layer of shock-absorbing material 70 to

100 mm (3- to 4-inch) thick around all sides of the module to provide firm cushioning and to prevent movement within the container.

• Seal the shipping container securely.

• Mark the shipping container FRAGILE to en-

sure proper handling.

• In any correspondence, refer to the module

by its model number and serial number.

• Temperature: − 40 °C to + 75 °C

• Humidity: Up to 90% at 65 °C

• Altitude: Up to 15,300 meters (50,000 feet)

The module should also be protected from temperature extremes which cause condensa tion on the instrument.

2-10. Tagging for Service

If the module is to be shipped to a Hewlett-Packard sales office for service or repair, attach a tag showing owner (with address), complete se ria l number, a n d a des cription of the service required.
