Environment
Description
The 4501 Model is a bidirectional switching system that operates between
DC to 18 GHz. 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.
