Keysight / Signametrics SMX2040 6.5-Digit PXI DMM Module

The Keysight/Signametrics SMX2040 is a 6.5-digit PXI Digital Multimeter module engineered for high-density automated test systems. This CompactPCI-compatible instrument delivers precise electrical characterization across DC/AC voltage and current, resistance, frequency, temperature, capacitance, inductance, and leakage measurements. The module integrates directly into PXI or CompactPCI chassis and connects to devices under test or switching cards with minimal integration overhead.
