02 Keysight M9186A PXI Voltage/Current Source Data Sheet
Product Description
The M9186A is a two-slot, PXI based V/I source module that enables the sourcing of a voltage or
a current to perform measurements on the resultant current or voltage through another module.
It consists of two separate amplifiers, denoted by “low” and “high” that share a common output
connection. 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 I/O pin parametric leakage, bias current,
impedance, threshold and clamp voltage. The high voltage amplifier can be applied to help verify the
presence of clamp diodes as the outputs of modules that drive inductive loads. Both the amplifiers
can sense the amount of current flowing while forcing a constant voltage.
Uniquely present is a safety interlock for the high-voltage amplifier that automatically disables
the high-voltage amplifier and opens all relays when the interlock circuit is broken. This provides
protection to the DUT when dangerous high levels of voltage maybe present. The interlock in
indicated by an LED on the module front panel and can be used, for example, by connecting
to an external limit switch on fixtures.
