Keysight / Agilent / HP E2270A 16-Channel Form A Switch

The Keysight E2270A is a 16-channel Form A switch module delivering electromechanical relay-based signal switching for automated test equipment systems. Each channel provides SPST (Single Pole Single Throw) contact performance with low thermal offset and minimal contact resistance, making it ideal for low-frequency signal routing where contact integrity is essential. The module integrates an 8-bit interface with FIFO capability for storing up to eight relay operations, enabling rapid sequential switching without host intervention. Relay closure and opening occurs in 8 milliseconds per operation. With typical relay life of 10⁵ operations at rated load, the E2270A delivers sustained performance in demanding switching applications. ## Technical Specifications **Switching Architecture**
