The Model 7062 is a 50Ω RF scanner card that plugs into a mainframe scanner such as the Keithley Model 705 or Model 706. The Model 7062 incorporates two sets of 1 X 5, 1-pole switching. Each set has its own common (ground). The Model 7062 has channels which are unterminated when not connected from one channel to another. The insertion loss at 500MHz is less than 3dB. Since there are two 1X5 switches, each having its own common, two signals can be routed through the card simultaneously. The 1X5 switch can be cascaded with another 1X5 switch for a 1 X 10 switch with minimal loss of frequency response. There are several switching schemes that offer flexibility from the Model 7062. Refer to Section 2 Operation. Specified relay life is greater than 100,000 closures. Cables are routed from the rear of the card. The front of the card plugs into the mainframe (e.g. Model 705 or Model 706). The mainframe operates in the matrix mode or 2-pole mode in order to control the channels. BNC connectors allow easy connection to input/output signal paths.
