ASCOR Breaks New Ground with the 4500 Series VXI Modules
Traditionally ATE systems have been designed using switching components wired together to form a system switch. This is especially true of VXI switch modules that are combined through external wiring components. The instrumentation then requires additional wiring to be integrated into this maze of switches. The disadvantage to this approach are the loss of performance due to mismatched impedance, signal loses due to long cables and higher resistive, capacitive or inductive loads due to poor wiring design. It is always ideal to design a good switch system to minimize cabling and match impedances.

The New 4500 Series Minimizes Cabling and Match Impedances

ASCOR has designed a new family of switches that minimizes cabling and match impedances by utilizing the existing 4000 series multi-slot carrier. Replacing the traditional VXI card front panel with a standard Virginia Panel TAC connector allows the Device Interface Board (DIB) to mate directly to the 4500 Series switch module. Test engineers no longer need to install a custom cable assembly between the individual switchcard front panels and the DIB interface. The 4500 Series ensures test signal integrity by shielding all signal connections starting from the internal switch assemblies through impedance matched transmission lines to the TAC connector interface The .4500 Series exploits receiver mechanism technology to ease problems with large front panel I/O connections.

The switch modules fit in a small carrier (either the 4000 Series carriers or the 4500 Series carriers) which is then inserted into our standard VXI Chassis.
