Measurement specialist Keithley Instruments announced an expansion of its Series 3700 System Switch/Multimeter and Plug-in Card family with the addition of two new plug-in cards, the Model 3724 dual 1X30 solid-state FET relay multiplexer card and the Model 3750 multifunction input/output (I/O) card. The former provides scan rates of greater than 1200 channels/s and offers 0.1 A at up to 200 V of switch/carry capacity with offset current of less than 10 nA.

The solid-state relays can be configured into either a dual 1 x 30 or 1 x 60 multiplexer. The latter card (model 3750), which is ideal for production test, features 40 digital I/O channels with high-current driver outputs that can sink up to 300 mA. It provides two programmable analog outputs offering both voltage and current programmable isolated analog outputs including 0 to 20 mA, 4 to 20 mA, or +/-12 VDC. It also comes with four totalizers/counters with 32-b resolution and is gated with a 1-MHz input rate. The firm's Series 3700 instruments include numerous features in support of automatic-test applications, including LXI Class B compliance with IEEE 1588 time synchronization.
