Environment
Description
The 4301 Model is a bidirectional switching system which operates between
DC to 18 GHz. The system can support up to (12) coaxial SP10T switches
at the maximum in a 4U chassis and (16) coaxial SP10T switches in a 6U
chassis. The switches are mounted independently on the rear panel and are
controlled separately; hence in a blocking configuration.
The unit can be controlled manually (locally) via a 4-line (4x40) LCD and
a keypad. Remotely, the system is offered with the choice of three control
interfaces: Ethernet, GPIB, or LXI protocol. Using specific SCPI commands,
one can control each individual SP10T switch. For detailed information,
contact Dow-Key's technical sales staff.
