The following safety precautions should be observed before using
this product and any associated instrumentation. Although some ins
strumcnts and acccssuries would normally hc used with non-haz­ardous voltages, there are situations where hazardous conditions
may bc prcscnt.

This product is intended for use by qualified personnel who recog­nix shack hazards and arc familiar with the safety precautions re­quired to avoid possible injury. Read the operating information
czcfully before using the product.

Safety Precautions

Do not connect switching c,uds directly IO unlimited power circuits.
They arc intended 10 he used with impcdancc limired wurcer.
NEVER connecL switching cards directly tu AC nuin. When cons
netting sources to switching cards, instill1 protcc~ivc dcviccs LO lime
it fault currem and voltage IU the card.

Exercise ex~cme caution when a shack hazard is present. Lethal
voltage may be present on cable connector jacks or test fixtures.
The American National Standards Institute (ANSI) states that a
shock hazard exists when voltage levels grcatcr than 30V RMS.

42.4V peak, or 60VDC arc present. A good safety practice is to ex-

pect that hazardous voltage is

present

in any unknown circuit

before measuring.

Before operating an instrument, make sure the lint cord is connect­ed to a properly grounded power receptacle. Inspect the connecting
cab&. test leads, and jumpers for possible wear, cracks, or breaks
before each use.

For maximum safety, du not touch the product, test cables, or any
other instruments while power is applied to the circuit under test.
ALWAYS remove power from the entire test system and dischrzge
any capacitors before: connecting or disconnecting cables or jump­ers, installing or removing switching cards, or making internal
changes, such as installing or removing jumpers.

Do not touch any object that could provide a current path to the
common side of the circuit under test or power line (earth) ground.
Always make mcasurcmcnts with dry hands while standing on a
dry, insulated surface capable of withstanding the voltage being
measured.

When fuses are used in a prodw. replace wilh ~ilmc type and rating
for conlinued protection againsl fire hazard.

Chassis connections must only he used as shield conncc~ions for
measuring circuits, NOT BS safety cwth ground connections.

If you are using a Tess lixturc. keep the lid closed while power is apt
plied to the device under test. Safe operation requires the use of B
lid interlock.

1fa @ screw is present, connect it 10 safety eanh ground using

#I 8 AWG or larger wire.

The f \ymhol on an instrument or accessory indicates that IOWV
or mom may be present on the terminals. Refer to the product mu
ual for detailed operating information.

Instrumentation and acccs~ories should not he conncctcd to hu-

IllB”E.

Maintenance should bc pcrformcd by qualified service personnel.

Before pctiorming any maintcnilnce. disconnect the line cord and

all ,CSI cables.

manual.

1.7 Unpacking and inspection

1.9 Repacking for shipment

1.7.1 Inspection for damage

The Model 7016 is packaged in are-sealable, anti-static bag
to protect it from damage due to static discharge and from
contamination that could degrade its performance. Before re­moving the card from the bag, observe the precautions on
handling discussed below.

1.7.2 Handling precautions

* Always grasp the card by the side cdgcs and covci-s. Do

not touch the board surfaces or components.

- After removing the card from its anti-static bag, inspecl
it for any obvious signs of physical damage. Repon any
such damage to the shipping agent immediately.

- When the card is not installed in a switching main­franc, keep the card in its anti-static bag, and store it in
the original packing carton.

1.7.3 Shipment contents

The following items are included with every Model 7016 or­der:

* Model 7016 5OQ GHz Multiplexer Card
. Model 7016 Instruction Manual

- Additional accessories as ordered

Should it become necessary to return the Model 7016 for re­pair, carefully pack the unit in its original packing carton or
the cquivalcnt, and include the following information:

- Advise as to the warranty stztus of the card.
* Write ATTENTION REPAIR DEPARTMENT on the

shipping label.

* Fill out and include the service form located at the back

of this manual.

1 .I 0 Recommended accessories

Recommended cables and lcrminating resistors are covered
below. Thcsc itcms arc not stocked by Keithley and must be
obtained from other sources.

1 .I 0.1 Connecting cables

The following cable type is recommended for making input/
output connections to the Model 7016: RG223N.

Other 50R cables may be used, bul keep in mind key pawn­eters as such as maximum outside diameter, attenuation over
the desired frequency range, flexibility, and shield type. See
paragraph 3.5 in Section 3 for mom information on cable pa­ramctcrs.

1.8 Instruction manual

If an additional Model 7016 Instruction Manual is required,
order the manual package, Keithlcy pact number 7016.901.

00. The manual package includes an instruction manual and
any pertinent addenda.

1 .I 0.2 Terminating resistors

The following terminating resistor is recommended for use
with the Model 7016:

Type: Female SMB terminator
Manufacturer: Sealecmo Corp.
Part number: 61-001-0101
Nominal resistance: 51 Q2, +I %.

Connections

2.1

This section includes information on making connections to
the Model 7016 and installing the card in the Model 7001/
7002 Switch System.

2.2

To maintain high-impedance isolation between channels,
care should be taken when handling the card to avoid con­tamination from such foreign materials as body oils. Such
contamination can reduce isolation rcsistancc. To avoid pos-

sible. contamination, always grasp the card by the side edges
or covers. Do not touch board surfaces, components, or con­nector insulators.

Dirt build-up over a period of time is another possible source
of contamination. To avoid this problem. operate the card in

a clean environment. If the cad becomes contaminated, it

should be thoroughly cleaned as explained in paragraph 4.2.

Introduction

WARNING

The procedures in this section are in­tended only for qualified service person­nel. Do not perform these procedures
unless you are qualified to do so. Failure
to recognize and observe normal safety
precautions could result in personal in-

jury or death.

This paragraph provides the information ncccssary 10 cow
necl your cxlernal test circuitry to the Model 7016.

2.3.1 Simplified schematic

Figure 2-l shows a simpliticd schematic diagram or the
Model 7016. The card is arranged into two separate multi­plexers. each with four channels.

2.3.2

Figure 2-2 shows the general conliguration of the Model

7016. Connectors include:
IN l-8 (channels l-8): Each input is equipped with an SMA

coaxial connector. The center conductor is the signal path,
while the outer shell connected to signal common.

OUT A and OUT B: Each multiplexer is equipped with an

SMA coaxial conocctor. The center conductor is the signal

path, and the shell is conncctcd to signal common.
Termination jacks: Each channel has an SMB coaxial tcr-

minator jack. User-supplied 5OG terminators can bc con­ncctcd to these jacks when a 5OQ nominal input impedance
must bc maintained for off channels.
