7174A High Speed, Low Leakage Current Matrix The Model 7174A provides an optimum solution to switching the lower level signals common to today's semiconductor characterization tests. The card's low leakage and minimal dielectric absorption ensure that key device measurements can be performed many times faster than with current switching technologies. Connections are 3-lug triax with the outer shell connected to chassis for safety and noise shielding. The center conductor is fully surrounded by the inner conducting shield allowing fully guarded measurements to be made with higher isolation and improved speed and accuracy. * Fast time to measurement * Low leakage (<100fA offset on all signal paths) * 2-pole switching, signal, and guard * 200V, 2A signal levels * Designed for use with Keithley Model 4200-SCS, 2635B and 2636B System SourceMeter(R) SMU Instruments, and Agilent B1500 For applications that require making connections to a large number of devices or test points, the Model 7174A matrix can be expanded with additional cards. On-card connectors are provided to connect the rows (column expansion) between other 7174A cards in adjacent slots of the Model 707B switching mainframe. Eight female-to-female cables are provided with each 7174A to simplify expan sion. Up to six 7174A cards can be connected in a single 707A switching mainframe to form an 8x72 or 12x60 matrix. * Compatible with Models 707A, 707B, 708A, and 708B MATRIX CONFIGURATION: Single 8 rowsx12 columns. Expanding the columns can be done internally by connecting the rows of multiple 7174A cards together with coax jumpers. CROSSPOINT CONFIGURATION: 2-pole Form A (Signal Guard). CONNECTOR TYPE: 3-lug triax (Signal, Guard, Chassis). MAXIMUM SIGNAL LEVEL: Pin-to-pin or Pin-to-Chassis: 200V. 2A carry current. CONTACT LIFE: Cold Switching: 108 closures. OFFSET CURRENT: 100fA max., 10fA typical (with 0V applied to inputs and outputs). ISOLATION: Path (Signal to Signal): >2x1014W, 1pF. Common (Signal to Chassis): >1014W, <10pF.

The Model 7174A is ideal for use with Keithley Models 2635B and 2636B System SourceMeter(R) SMU Instruments, Model 4200-SCS, and the Agilent B1500. The card's configuration is 8 rows x 12 columns, with signal and guard switched at each crosspoint. Offset current has been reduced dramatically to <100fA on all pathways. Significant reductions in the level of parasitic capacitances in the Model 7174A help speed the process of making low level measurements.
