The Keithley 7016A is a dual 1×4 multiplexer card delivering independent, bidirectional RF signal routing across two isolated channels. Each multiplexer connects one common port to four selectable inputs, operating from DC to 2GHz with 50Ω characteristic impedance. Designed as a plug-in module for Keithley 7001 and 7002 switch mainframes, the 7016A enables flexible high-frequency signal management in automated test systems requiring repeatable, low-distortion switching.
The card employs Form A relay contacts with 120mA drive current and 8ms actuation time. SMA connectors interface to external circuits; SMB terminator jacks accommodate user-supplied 50Ω loads on unselected inputs to suppress reflections. Contact resistance measures 0.5Ω with 1GΩ with <50pF capacitance.
