The modular architecture of the GX7016 allows the switching subsystem to support a wide range of configurations and capabilities. Input analog signal routing is supported by the GX6032, a matrix switch module which is located on the rear of the chassis. This module is configured as 32 x 16 matrix and supports up to 32 inputs which can be connected to the GX7016’s internal 16 wire bus. Up to (4) of these modules can be supported by the system. The base system is supplied with (1) GX6032.
Signal routing from the internal backplane to the receiver interface is supported by the GX6256 MultiMatrix™ switch card which is an extended 6U PXI module with direct connection to the receiver interface. The module combines a 16x16 matrix with (16) 2:16 multiplexers. The result is a switch card that can support up to 256 multiplexed signals from the 16 wire bus. Additionally, a secondary bus is included, providing the ability to route (2) resources to each group of 16 I/O pins within a mux group. The GX6256 also supports the ability to select an analog or digital resource (GX5960 digital subsystem) for each of the 16 inputs/ outputs.
For higher performance analog switching applications, the GX7016 can be configured with the GX6192 HF MultiMatrix™ switch cards which combines a 16x16 matrix with (16) 1x12 multiplexers, providing a total of 192 high performance I/O pins at the receiver interface. HF resources are connected directly to the GX6192 via an external connector. In addition, signals can be routed to / from the HF switch card to other switch cards in the system via the system’s internal 16 wire bus.
The GX7016 switching subsystem includes the following components:
● GX7016 – 6U PXI chassis with a special backplane used for plugging in the SR, RTM in addition to the PXI boards LF and HF
● GX6009 - Switching Routers modules (SR)
● GX6032 - Rear Transition modules (RTM)
● GX6192 - High Frequency multiplexer PXI boards (HF)
● GX6256 - Low Frequency multiplexer PXI boards (LF)
● GX6864 – Video multiplexer PXI boards (VF)
In addition to the GX6256 and GX6192 switching function, they are also used control an RTM and an SR that are mounted to backplane since these cards do not sit on the PXI bus.
