ViaLiteHD
products are fitted with a range of standard RF connectors. The RF modules are all fitted with FEMALE connectors. When
connecting the modules ensure that you have both the correct type and impedance of connector. Listed below are the connector types
available.
Front panel test connectors, plug in modules only
BNC
50 ohms
bayonet

F-Type
75 ohms screw on
Not all connector types are available on all types of module. If you are unsure of the connector type your module is fitted with this can be
determined from the part number (see section 5). Blind mating modules are fitted with a floating RF connector, mating between the plug in
module and the chassis rear plate. This is a purely internal interface and should not be connected by any means other than via the supplied
chassis interface.
Warning! Use of incorrect impedance connectors may also cause intermittent connections and in extreme cases result in
physical damage to the connector.
Warning! Use of incorrect impedance connector will result in mismatch increasing the system loss and reducing flatness.
Warning! Use of incorrect impedance cable will result in mismatch increasing the system loss and reducing flatness.

All modules are fitted with one, two or three rear RF ports. All new Blindmate modules are supplied with an appropriate chassis interface
plate. LEFT and RIGHT refer to connection to adjacent module, referenced to the front view.
