A single Keithley 7002 mainframe can accommodate up to ten 40-channel cards. That's 400 channels in a single full-rack package that is only 178mm high (7 in). This level of density provides some important advantages. First, it reduces the amount of switching hardware required for a given application. Second, it provides high flexibility. The high density cards can be used with the special signal cards to cover all your signal needs for a large application with one mainframe.
The Keithley 7002 is fully compatible with all Keithley 7001 switch cards. From this broad selection of more than 40 cards, you can assemble a switch configuration that will ensure signal integrity and minimize errors. These cards allow the Keithley 7002 to switch DC signals from femtoamps to amps, nanovolts to kilovolts, as well as RF and optical signals.
