Overview
The National Instruments PXI-4022 guard and current amplifier is a PXI
accessory module consisting of a high-speed, high-precision amplifier
that conditions signals for measurement devices. With the guarding
functionality, you can make 6-wire resistance measurements for resistors
connected in a network, on complex printed circuit board layouts, or
cable test applications. For low-current measurements, the NI PXI-4022
amplifier and high-precision resistors create a feedback current
amplifier. This implementation minimizes burden voltages and converts
current to voltage, so you can measure pA signals with fA noise.
Add Functionality to DMMs
and Data Acquisition Devices
You can use the PXI-4022 with NI PXI-407x digital multimeters (DMMs)
for 6-wire resistance/capacitance measurements or ultralow-current
measurements in a wide variety of applications. You also can use it with
an M Series data acquisition device to form a low-cost, high-resolution
acquisition module for basic in-circuit test needs.
Software
The PXI-4022 is shipped with NI-DMM driver software, an IVI-compliant
driver that provides numerous example programs and access to the
complete functionality of the PXI-4022 through an easy-to-use
application programming interface (API).
