Description
The PXI-4022, with a part number of 779614-01, is categorized as a PXI Amplifier Module. It is primarily designed for use as a guard and current amplifier for digital multimeters, enhancing their performance and accuracy. This module stands out with an impressive input impedance of greater than 1010 Ω and an input bias current of less than 5 pA, ensuring minimal interference with the measurement circuit.
It offers a maximum output voltage range of ±12 V along with a maximum output drive current of ±15 mA. Designed to handle signal voltages of up to 250V, the PXI-4022 is also remarkably robust, boasting a surge voltage tolerance of up to 2,500 V. This makes it well-suited for applications in Measurement Category II environments where transient overvoltages are a concern.
The module features low-EMF, low-leakage, gold-plated, solid copper input terminals, which contribute to its high accuracy and reliability. Additionally, it is equipped with comprehensive overvoltage protection including Guard out, Guard In “+”, and Guard In “-” to protect the device and the measurement setup from sudden voltage spikes.
On its front panel, the PXI-4022 houses 5 connectors, including Guard/amplifier output, Guard/amplifier positive input, Guard-Sense/amplifier negative input, and two Floating common (LO) connectors. The back mounted connectors include 2 ports for the module’s floating ground, ensuring easy integration and robust grounding options for various test and measurement setups.
Configuration and automation are made simple with the inclusion of MAX (Measurement & Automation Explorer) software, allowing for efficient setup and control of the PXI-4022 in complex systems. This software compatibility further enhances the module’s versatility and ease of use in a wide range of applications.
