Insertion Loss Isolation VSWR
CXR/2(4x1)-LL SWITCH MODULE
Dual 4x1 low leakage modules can be used to measure
currents down to 50 femtoamps (5x10E-14 amps), or re-
sistances up to teraohms (10E+12). Maximum switched
voltage of 1500 VAC. It is available with either BNC (normal
low leakage), Triax (fast driven guard) or SHV ( > 100 Tera
ohms) connectors.
The module may be used in Cytec CXAR Series 16, 32, or
10.5" high 128 channel chassis. Bus bars are available to
form larger multiplexers or matrices. Custom congurations
are available.
CXS SOLID STATE CABLE TV or MODEM MODULE
CXS/8x1-GT-75 Switch Module
This switch is identical in function to the electro-mechanical
relay version of our 75 ohm 1x8 mux, but the use of solid state
components makes it operate with very good specications
over the frequencies of 1 to 900 MHz commonly used for
cable modems and cable TV. Available with BNC or F type
connectors. This switch module ts in any standard Cytec
CXAR Series chassis.
CXR LOW LEAKAGE MODULE
This module is designed with for applications where you need to measure extremely low currents or
extremely high resistence. The module is arranged as two 4x1 sections that can be wired as an 8x1, 4x2
or many other congurations. A schematical representation of the module is shown in Fig. 11. Many
jumpering options allow this module to be grounded or ungrounded or used with a driven guard circuit
to improve speed and accuracy. Above board wiring with coax cables keeps noise and charge times to
a minimum. Combinations of these modules can be assembled to form larger multiplexers or matrices.
Contact a Cytec specialist to discuss which options are best for your specic application.

These modules are designed for 75 ohm applications operating at frequencies from DC to 1 GHz, mak-
ing them perfect for cable TV and cable modem applications. Terminated inputs and outputs guarantee
impedance matching on unused channels. Insertion loss is at within 1 dB over the range of 1 MHz to
1000 MHz.

CXS/16x1-GT-75-F Switch Module
This is a 16x1 version of the solid state switch with F connec-
tors as shown in Fig. 13. The specications are the same
as shown above.
Up to 8 of these modules may be installed into a standard
Cytec CXAR/8(16x1) Mainframe or Expansion Chassis.
