1.9 ACCESSORIES
The following accessories are available from Keithley In-
struments to enhance the capabilities of the Model 224 Pro-
grammable Current Source.
Model 1019A Universal Rack Mounting Kit-The Model
1019A Universal Rack Mounting Kit can accomodate one or
two Model 224’s. The dimensions are 133mm x 483mm
(5%in. x 19in.I.
Model 1019s is a slide type universal rack mounting kit. The
kit will accomodate up to two half rack size instruments (e.g.
Model 224) in a standard 5%” X 19” rack.
Model 2243 IEEE-488 Interface-The Model 2243 is an op-
tional IEEE-488 interface for the Model 224 Programmable
Current Source. This interface adds extra versatility to the
Model 224 by allowing the transmission of data and com-
mands over IEEE-488 bus. The interface provides all the logic
necessary to interface the Model 224 to the bus using stan-
dard IEEE-488-1978 protocol. Additionally, the Model 2243
incorporates a separate digital I/O port that may be used to
interface the Model 224 to other digital instrumentation.
Model 6011 Triax Input Cable-The Model 6011 is a three
foot (1 meter) low noise triax cable terminated with alligator
clips at one end and a Teflon*
insulated triax connector at
the other end.
Model 6147 Triax to BlilC Adapter-The Model 6147 Triax to
BNC Adapter allows the Model 224 to be used with all
Keithley accessories and cables that require BNC connec-
tions.
Model 6167 Guarded Adapter-The Model 6167 Guarded
Adapter reduces effective cable capacity by driving the inner
shield of a triaxial cable at guard potential.
Model 7008-3 IEEE-488 Cable-The Model 7008-3 is a three
foot (1 meter) IEEE-488 cable. The cable has 24 stranded wire
conductors and is terminated with IEEE-488 standard con-
nectors.
Model 7008-6 IEEE-488 Cable-The Model 7008-6 is a six
foot (2 meter) IEEE-488 cable. The cable has 24 stranded wire
conductors and is terminated with IEEE-488 standard con-
nectors.
Model 7010 Cable Adapter-The Model 7010 is an IEEE-488
cable adapter. The adapter extends the IEEE-488 connector
by one connector width for easy access connections.
Model 7051-2-The Model 7051-2 is a BNC to BNC shielded
cable that is 2 feet long. This cable is especially useful when
utilizing the external input and output trigger connectors.
Model 7051-5-The Model 7051-5 is a BNC to BNC shielded
cable that is 5 feet long. This cable is especially useful when
utilizing the external input and output connectors.
