Description
Overview
The Keysight 400EL is a precision AC voltmeter designed for laboratory and field measurements. It features dual measurement scales—a linear AC scale with an integrated logarithmic dB scale underneath—allowing technicians to measure both voltage and power ratios simultaneously. Calibrated across a broad frequency range from 10 Hz to 10 MHz, the instrument provides reliable readings across diverse applications.
Key Features
- Dual scales: linear AC scale with logarithmic dB scale
- Voltage measurement range: 1 mV to 300 V
- dB range: −72 dBm to +52 dBm
- Wide frequency response: 10 Hz to 10 MHz calibration
- High accuracy: ±4% (10–20 Hz), ±2% (20–40 Hz), ±1% (40 Hz–2 MHz), ±2% (above 2 MHz)
Applications
- AC voltage measurements in laboratory settings
- Audio and RF frequency measurements
- Power ratio measurements in decibels
- Frequency response testing
