The 4x-785C family is based on Radiall mechanical microwave switches. The addition of 67 GHz 50 Ω internally terminated switches allows unused channels of a test system to be terminated in the characteristic impedance of the signal path, thus maximizing signal integrity.
Remote mount options connect each switch to the control module via a 1.5 M cable providing flexibility in switch positioning. This reduces the length of RF connections, thus maximizing performance and minimizing cabling costs. Chassis slot count is minimized as only 3-slots are required for a single configuration – or 6-slots for dual panel mount switch – or just a single slot for the remote mount versions.
“To aid with test system health monitoring, the 4x-785C family is provided with a switch cycle counting feature,” said Steve Edwards, Switching Product Manager at Pickering Interfaces. “Determining the number of operations per channel can help manage the wear-out process by allowing alternate lower usage paths to be substituted for high-use channels.”
