The M9186A VI source from Keysight
With the V/I source, you can inject a voltage and measure the resulting current or inject a current and measure the resulting voltage. It consists of two separate amplifiers, called "low" and "high", which have a common output terminal. The "low" amplifier provides voltages in the range of 16 volts at up to 200 mA and the "high" amplifier provides voltages in the range of 100 V at up to 20 mA.
Typical applications for the low voltage amplifier include parametric leakage at I/O pins, bias current, impedance, threshold and clamp voltage. The high voltage amplifier can be used to check for the presence of clamping diodes on the outputs of modules driving inductive loads. Both amplifiers can measure the amount of current flowing while forcing a constant voltage.
Uniquely, a safety interlock for the high voltage amplifier automatically disables the high voltage amplifier and opens all relays if the interlock circuit is broken. This provides protection for the monitoring system when dangerous high voltages may be present. Interlocking is indicated by an LED on the front of the module and can be used, for example, by connecting to an external limit switch on fixtures.
