7158

The 7158 is a Scanner Card provides quality low-current switching. The offset current error generated is specified < 1pA with typical performance at <30fA. When used with a voltage source and electrometer or picoammeter, this card can easily automate insulation resistance tests, reverse leakage tests on semiconductor junctions or gate leakage tests on FETs. It is designed to maintain the current path even when channel is deselected. Input connectors are BNC for shielding of sensitive measurements and for compatibility with low noise coaxial cables such as Keithley accessory cables models 4801 and 4803. Two outputs are provided to allow for chaining several scanner cards to one measurement instrument and isolation relay in the output HI minimizes interaction between cards. It offers contact configurations of single pole, simultaneous break and make for signal HI input, signal LO is common for all 10 channels and output and when a channel is OFF, signal HI is connected to signal LO.
