Agilent/Keysight 34524A

The Agilent/Keysight 34524A is a data acquisition and switch unit engineered for automated test systems. It delivers signal routing and conditioning capabilities essential for accurate measurement data collection in R&D, manufacturing, and quality control environments.

Technical Specifications

The 34524A integrates a 6½ digit (22-bit) internal digital multimeter with basic DCV accuracy of 0.004%. Measurement functions include DC/AC volts, DC/AC current, 2- and 4-wire resistance, temperature sensing via thermocouples, RTDs and thermistors, and frequency and period analysis. Scan rates reach 250 channels per second. Operating temperature ranges from 0 °C to 55 °C with 20% to 80% relative humidity (non-condensing) at 40 °C or less. The unit operates reliably at altitudes up to 2000 meters.
