The EX1200-6216 is a high-density RF switch module configured as dual 1 x 16 coaxial trees that
are isolated from each other and system ground to provide a high-fidelity switch path for
switching signals in excess of 1 GHz in a 50 Ω environment. On-board jumpers can be added to
connect all shields together or to system ground if desired. Excellent crosstalk and isolation is
maintained by using very short low-loss coaxial runs from the connector directly to the relays.
All modules are also configured to avoid any unterminated stub effects. This improves overall
signal integrity and allows for high frequency matrix designs or large multiplexer configurations
while preserving bandwidth and maintaining low VSWR. The front panel utilizes two high-
density, 26-pin coaxial connectors designed for high reliability and low insertion loss.
Six of the modules can be accommodated in a 1U EX1200 full rack mainframe to provide a very
flexible RF switch network. The modules can also be combined with other EX1200 switch cards
to configure a general purpose subsystem to switch dc to > 1 GHz.
The EX1200-6216 can be controlled programmatically using IviSwtch-compliant calls. Both path
level programming and individual relay control are available. Refer to the host driver
documentation for additional details.

Figure 4-6 provides a logical diagram of the switch module
and identifies the switches used by the module. This information can be used for individual relay
control through the driver. Both single-wire and two-wire programming modes are available.
