The Keysight M9122A is a PXI matrix switch module delivering an 8×32 full crosspoint configuration for signal routing in automated test systems. This armature relay-based switch matrix handles up to 100 Vrms and 2 A per channel with 60 W maximum power dissipation, making it suitable for moderate-power switching applications. Switching speed is 3 ms. The module connects via a 50-pin D-Type front panel connector and supports both durable connector block and standard cable terminations. It uses an 8-wire wide bus with common ground configuration and operates across 0 °C to +55 °C at up to 95% non-condensing humidity.
