    The Model 7071-4 Dual 4x12 General Purpose Matrix Card provides the capability to expand the number of columns that the Model 707A will support to a maximum of 720 in five 707A mainframes. This matrix card has two banks of four signal paths that connect through jumpers to the general purpose analog backplane in the 707A mainframe for automatic interconnect between cards. Jumpers may be removed to isolate any 4x12 matrix segment or repositioned to cascade segments into a 4x24 configuration. Includes: Screw terminal adapter for 4x24 configuration.


    7072 8x12 Semiconductor Matrix Card

    • Two 1300V, sub-picoamp current paths
    • Six 200V, 20pA paths
    • For use with Model 2410 and Model 237 SMU
    • 3-lug triaxial connections
    • Compatible with Models 707A, 707B, 708A, and 708B

    The Model 7072 Semiconductor Matrix Card is designed specifically to handle low-level and high-impedance measurements encountered in semiconductor parametric tests on wafers and devices. This unique design provides two low-current circuits with specified 1pA maximum offset current for sensitive sub-picoamp measurement resolution and two C-V paths for measurement of Capacitance Voltage characteristics from DC to 1MHz. Four additional high-quality signal paths with <20pA offset current provide for general-purpose signal switching up to 100nA or 200V. 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, so that fully guarded measurements can be made to achieve higher isolation and to improve measurement speed and accuracy. Isolation relays on the low-current and C-V paths automatically disconnect unused circuits to achieve minimum interference and peak performance. The 707A or 708A mainframe allows each row (signal path) to be programmed for Break-Before-Make or Make-Before-Break operation. For applications requiring connections to a large number of devices or test points, the 7072 matrix can be expanded with additional cards. The low-current and C-V rows can be extended to other cards with coaxial jumpers. The other four high-quality signal paths connect directly to the 707A backplane for expansion. Includes: Instruction manual and four SMB expansion cables (CA-54-1)


    7072-HV 8x12, High-Voltage, Semiconductor Matrix Card

    • Two 1300V, sub-picoamp current paths
    • Six 200V, 20pA paths
    • For use with Model 2410 and Model 237 SMU
    • 3-lug triaxial connections
    • Compatible with Models 707A, 707B, 708A, and 708B

    The Model 7072-HV is designed to switch lowlevel, high-voltage, and high-impedance signals for semiconductor parametric tests on wafers and devices. This unique design provides two signal paths capable of switching 1300V with less than 1pA of offset current. The two C-V paths may be used for measurement of capacitance voltage characteristics from DC to 1MHz or for switching low currents with a common ground. Four additional high quality signal paths with less than 20pA offset current provide for signal switching to 200V.


    7173-50 High-Frequency, 2-Pole, 4x12 Matrix Card - Discontinued

    • 200MHz bandwidth
    • <2ns rise time
    • 50Ω impedance
    • <15μV offset
    • <200pA offset current
    • 2-pole switching
    • Compatible with Models 707A, 707B, 708A, and 708B

    The Model 7173-50 combines high frequency performance with excellent DC switching characteristics. It provides 200MHz bandwidth in a 4x12 configuration. Offset voltage is <15μV per crosspoint, and offset current is <200pA. The combined AC and DC capabilities make it ideal for mixed signal applications where both high frequency and low level DC signals must be switched ™ for example, testing ADCs or DACs, which involves measuring both digital and analog signals.


    7174A 8x12, Low-Current, High-Speed Matrix Card

    • Fast time to measurement
    • Low leakage (<100fA offset on all signal paths)
    • 2-pole switching, signal, and guard
    • 200V, 2A signal levels
    • Compatible with Model 707A and 708A Switching Matrix Mainframes
    • Designed for use with Keithley Model 4200-SCS, SMUs, 2635A and 2636A SourceMeter® Instruments, and Keysight B1500
    • Compatible with Models 707A, 707B, 708A, and 708B

    The Model 7174A Low Current Matrix Card is designed for semiconductor research, development, and production applications requiring high quality, high performance switching of I-V and C-V signals. The Model 7174A is ideal for use with Keithley Models 2635A and 2636A SourceMeter Instruments, Model 4200-SCS, and the Keysight 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. 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 measurementscan 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.

    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 707A switching mainframe. Eight female-to-female cables are provided with each 7174A to simplify expansion. Up to six 7174A cards can be connected in a single 707A switching mainframe to form an 8x72 or 12x60 matrix. Includes: Eight row interconnect cables for card to card matrix expansion.
