The Keysight/Agilent/HP E1368A is a 3-channel microwave switch module that routes signals across DC to 18 GHz for automated test and measurement systems. Each channel implements a single-pole, double-throw (SPDT) architecture with 50 Ohm termination, delivering exceptional isolation and low insertion loss across the full frequency range. This B-size, 1-slot VXI component integrates three integrated 8762B microwave switches, controlled via SCPI commands and a latching solenoid mechanism.
