The system supports up to (4) coaxial SP6T terminated switches, which are mounted on the front panel in a 3U chassis with no interconnections; hence in blocking fashion. A 2-line (2x40) LCD, with 16 button keypad, on the front panel allows the user to manually controlled the switches. An on/off power switch is located on the front panel as well. Remotely, the system is offered with the choices of three control interfaces: Ethernet, GPIB, or LXI protocol. Using specific SCPI commands, one can switch individual coaxial switches. Best used for RF signal switching among exchangeable devices in test bench setup that requires easy access to RF I/Os.
