It provides an 8 row by 12 column matrix configuration with three-lug triaxial connectors carrying Signal, Guard, and Chassis conductors, where the outer shell is connected to chassis for safety and noise shielding and the center conductor is fully surrounded by the inner conducting shield to provide fully guarded measurements with higher isolation and improved measurement speed and accuracy. The 7072-HV is intended for semiconductor device and material characterization. The high voltage signals encountered in breakdown measurements or oxide integrity testing can be switched with this matrix card, with signals connected to the High V, Low I paths automatically isolated from the rest of the card. The two C-V paths may be used for measurement of capacitance voltage characteristics from DC to 1 MHz or for switching low currents with a common ground. Four additional high quality signal paths with less than 20 pA offset current provide for signal switching to 200 V. ## Brand Heritage Keithley Instruments was founded in 1946 in Cleveland, Ohio and became a long-established specialist in low-level and precision electrical measurement. Keithley was acquired by Danaher Corporation in 2010 and, following the 2016 spinoff of Danaher's industrial businesses, is now part of Fortive Corporation alongside Tektronix. Instruments bearing the Keithley brand continue to be developed and supported under that lineage. ## Product Core & Specifications Specification Value Matrix Configuration 8 rows by 12 columns Connector Type Three-lug triaxial (Signal, Guard, Chassis) Contact Life (Cold Switching) 107 closures Contact Life (At Maximum Signal Level) 105 closures Path Resistance (per conductor) <1Ω initial, <3.5Ω at end of contact life Relay Settling Time <15 ms Insertion Loss (1 MHz, 50Ω source, 50Ω load) 0.1 dB typical EMC Conforms to European Union Directive 89/336/EEC Safety Conforms to European Union Directive 73/23/EEC (meets EN61010-1/IEC 1010) Operating Environment 0° to 50°C, up to 35°C at 70% R.H.

Maximum between signal and guard is 200 V, with 1 A carry / 0.5 A switched and 10 VA peak (resistive load).**Important:** The 7078-TBC 3-Lug Female Triax Bulkhead Connector with Cap is rated for use at 200V or less, per the datasheet's accessories listing.**Important:** The 7072-HV requires a compatible switching matrix mainframe (Models 707A, 707B, 708A, or 708B). The mainframe is not included with this matrix card.**Important:** Connection accessories (triax cables, adapters, bulkhead connectors) are not included with the base card and must be ordered separately based on the system configuration.Recommended pairing: the 7072-HV is designed for use with the Keithley Model 237 SMU, Model 2410 SourceMeter instrument, Model 6487 Picoammeter/Voltage Source, or Model 6517B Electrometer/High Resistance Meter named in the datasheet, and installs into the Keithley 707A, 707B, 708A, or 708B switching matrix mainframes. **Please review the Manufacturer's Data Sheet to verify published specifications.
