The Keithley 7062 is a dual-channel RF switching card that routes signals across five independent paths per switch. Housed on a single plug-in card compatible with 7001 and 7002 mainframes, it delivers two independent 1-pole, 5-throw switches with 50 Ω characteristic impedance and 500 MHz bandwidth. The card supports signal levels up to 24 V, 50 mA, and 0.5 W, with contact resistance below 2 Ω and contact potential under 20 µV. Insertion loss remains below 0.1 dB up to 20 MHz, below 1.0 dB to 250 MHz, and below 3.0 dB to 500 MHz. Channel-to-channel isolation exceeds 75 dB below 20 MHz, 55 dB below 250 MHz, and 60 dB below 500 MHz. Switch-to-switch isolation surpasses 80 dB below 20 MHz, 70 dB below 250 MHz, and 60 dB below 500 MHz. Propagation delay is under 2 ns with actuation and release times of 10 ms and 5 ms respectively. BNC connectors interface with external RF paths. Contact life exceeds 10⁶ cold-switching closures or 10⁵ closures at maximum signal levels. An expansion connector enables cascading for larger switch matrices. Coaxial design provides inherent shielding and noise immunity while maintaining signal integrity across the measurement bandwidth.
