The Keysight 34465A is a 6½-digit digital multimeter delivering high-accuracy measurements across 12 distinct functions through patented Truevolt technology. Designed for electronics testing, troubleshooting, and calibration, this instrument combines exceptional resolution with true RMS capability and low-noise measurement architecture for demanding laboratory and field applications.
Technical Specifications
The 34465A achieves 30 ppm (0.003%) basic DC voltage accuracy with 6½-digit resolution. DC voltage measurement spans 100 mV to 1000 V; AC voltage ranges to 750 V across a 3 Hz to 300 kHz bandwidth. DC current measurements operate from 1 µA to 10 A, while AC current ranges from 100 µA to 10 A. Resistance measurement extends from 100 Ω to 1 GΩ in both 2-wire and 4-wire modes. The instrument captures up to 50,000 readings per second at 4½-digit resolution and logs up to 50,000 readings standard, with optional memory expansion to 2 million readings.
Truevolt technology eliminates measurement errors from noise, injected current, and input bias current—critical for low-power device testing and high-confidence circuit characterization. Auto-calibration (ACAL) maintains measurement integrity across temperature drift without manual intervention.
