Contact Potential (differential) - <±2 µV, <±2.5 µV
Offset Current - <10 nA, <10 nA
Isolation - Differential, 109ω, 500 pF, 109ω, 1100 pF
The Keithley 3724 is a dual 1×30 FET multiplexer card. The Model 3724 provides two independent banks of solid-state relays arranged as 1×30 two-pole multiplexers that are ideal for high reliability, high speed multipoint measurement applications including temperature. The two banks can automatically be connected to the Series 3700A mainframe backplane and optional DMM through the analog backplane connection relays. This connection allows the mainframe to reconfigure the card to a single 1×60 two-pole multiplexer or to enable card-to-card expansion for even larger configurations.
