Astronics / EADS / Racal 4152A 6.5 Digit Digital Multimeter

The Astronics/EADS/Racal 4152A is a 6.5-digit VXIbus digital multimeter engineered for high-throughput automated test systems. This single-slot C-size VXI module delivers simultaneous DC and AC voltage and current measurements alongside 2/4-wire resistance, frequency, and DC ratio capabilities—all in one compact instrument. Built for production environments requiring rapid measurement cycles, the 4152A supports limit testing, averaging, math operations, and vector calculations with exceptional switching speed: up to 65 range changes per second and 30 function changes per second.
