Keithley
7062

The Keithley model 7062 is a 50 ohms, RF Switch Card with two independent 1 of 5 switches and unterminated inputs for scanners model 705, 706, 7001 and 7002.
The 7062 have two independent 1 of 5 switches. Each switch has a separate through connection that can be used to cascade sections to achieve larger scanning configurations in multiples of five.
The switched transmission line design maintains the 50 ohms characteristic through the switch, minimizing reflection and loss. This approach results in reduced capacitance and better frequency response.
A 500 MHz bandwidth assures signal integrity over a broad range from DC to communications signals and digital waveforms.
Coaxial switching provides additional shielding and noise immunity in the system environment.
