Safety Precautions
The following safety precautions should be observed before using this product and any associated insrmmentation. Although some instmments and accessories would normally be used
with non-hazardous voltages, there are situations where hazardous conditions may be present.
This product is intended for use by qualified personnel who recognize shock hazards and are
familiar with the safety precautions required to avoid possible injury. Read the operating ins
formation carefully before using the product.
The types of product users are:
Responsible body is the individual or group responsible for the use and maintenance of
equipment, for ensuring that the equipment is operaled within its specifications and operating limits, and for ensuring that operators are adequately trained.
Operators use the product for its intended function. They must be trained in electrical safety
procedures and proper use of the insmnncnt. They must be protected from electric shock and
contact with hazardous live circuits.
Maintenance personnel perform routine procedures on the product to keep it operating. for
example, setting the line voltage or replacing consumable materials. Maintenance procedures
are described in the manual. The procedures explicitly state if the operator may perform them.
Otherwise, they should be performed only by service personnel.
Service personnet are trained to work on live circuits, and perform safe installations and repairs of products. Only properly trained sewice personnel may perform installation and ser.
vice procedures.
Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on
cable connector jacks or test fixtures. The American NationaJ Standards Institute (ANSI)
states that a shock hazard exists when voltage levels greater than 30” RMS, 42.0 peak, or
60VDC are present. A good safety practice is to expect that hazardous voltage is present
in any unknown circuit before measuring.
Users of this product must be protected from electric shock at all times. The responsible body
must ensure that WWF are prevented access and/or insulated from every connection point. In some
cases, connections must be exposed to potential human contact. Product users in these circumstances must be trained to protect themselves from the risk of elecnic shock. If the circuit is capable of operating at or above 1wO volts, no conductive part of the circuit may be exposed.
As described in the lntemational Electrotechnical Commission (IEC) Standard IEC 664, digital multimeter measuring circuits (e.g., Keitbley Models 175A, 199. 2000, 2001. 2002, and
2010) are installation Category II. All other instruments’ signal terminals are Installation Category 1 and must not be connected to mains.
Do not connect switching cards directly to unlimited power circuits. ‘Ibey are intended to be
used with impedance limited sources. NEVER connect switching cards directly to AC mains.
When connecting sources to switching cards, install protective devices to limit fault current
and voltage to the card.
Before operating an instrument, make sure the line cord is connected to a properly grounded
power receptacle. Inspect the connecting cables, test leads, and jumpers for possible wear,
cracks, or breaks before each we.
For maximum safety, do not touch the product, test cables. or any alher insbunents while power is applied to the circuit under test. ALWAYS remove power from the entire test system and
discharge any capacitors before: connecting or disconnecting cables or jumpers, installing or
removing switching cards, or making internal changes, such as installing or removingjumpers.
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 measurements with dry hands while
standing on a dry, insulated surface capable of withstanding the voltage being measured.
The instrument and accessories most be used in accordance with its specifications and operating instructions or the safety of the equipment may be impaired.
Do not exceed the maximum signal levels of the insuuments and accessoties. as defined in
the specifications and operating information. and as shown on the instrument or test fixture
panels, or switching card.
When fuses arc used in a product. replace with same type and rating for continued protection
against fire hazard.
Chassis connections most only be used as shield connections for measuring circuits, NOT as
safety earth ground connections.
If you are using a test fixture, keep the lid closed while power is applied to the device under
test. Safe operation requires the use of a lid interlock.

death. Always read the associated information very carefully before performing the indicated
procedure.

Such damage may invalidate the warranty.
instrumentation and accessories shall not be connected to humans.
Before performing any maintenance, disconnect the line cord and all test cables.
To maintain protection from electric shock and fire, replacement components in mains cir-
cuits, including the power uansfomxr, test leads, and input jacks, most be purchased from
Keithley Instruments. Standard fuses, with applicable national safety approvals, may be used
if the rating and type are the same. Other components that are not safety related may be purchased from other suppliers as long as they are equivalent to the original component. (Note
that selected parts should be purchased only through Keithley Insnuments to maintain accoracy and functionality of the product.) If you are unstxe about the applicability of a replacement component, call a Keithley lnsouments office for information.
To clean an instrument, use a damp cloth or mild, water based cleaner. Clean the exterior
of the instrument only. Do not apply cleaner directly to the insounent or allow liquids to
enter or spill on the instrument. Products that consist of a circuit board with no case 01 chassis (e.g., data acquisition board for installation into a computer) should never require cleaning if handled according to instructions. If the board becomes contaminated and operation
is affected, the board should be returned to the factory for proper cleaning/servicing.

SECTION 1
GENERAL INFORMATION
1.1 INTRODUCTION
The Model 7063 is an RF scanner card that switches RF signals (up to
500MHz) from one channel to another. All channels switched are
terminated into 5011 when not selected. When a channel is closed, the
RF signal is routed from the input to the output. The Model 7063
works in conjunction with a scanner mainframe such as the Keithley
Model 705 or Model 706.
The Model 7063 incorporates two 1 X 5, switches on each card.
Each switch has a separate common (ground). This allows two
signals to be switched at the same time. One 1 X 5 switch could be
cascaded with the other 1 X 5 switch (on the same card) for a 1 X 10
switch configuration. Thus, the Model 7063 is configurable for
several different switch configurations.
Specified relay life is greater than 100,ooO closures. Cables are routed
from the rear of the card. The front plugs into the mainframe (e.g.
Model 705 or Model 706). The mainframe must be in the matrix
mode or 2-pole mode to operate the channels on the Model 7063
card. BNC connectors allow easy connections to input/output signal
paths.
1.2 WARRANTY INFORMATION
Warranty information is stated on the inside front cover of this
manual. If there is a need for service, contact the Keithley represen-
tative or authorized repair facility in your area. Check the back
cover for addresses. The service form supplied at the end of the
manual should be used to provide the service facility with adequate
information concerning any difficulty.
1.3 MANUAL ADDENDA
Improvements or changes to this manual will be explained on an addendum included with the manual. It is recommended that this information be incorporated immediately into the appropriate places in
the manual.
