Description
Overview
The Keysight 478A is a high-accuracy coaxial thermistor mount designed for RF power measurement from 10 MHz to 10 GHz. When used with Keysight 432A or N432A power meters, it delivers high-accuracy measurements even in routine power measurement applications. The thermistor element is temperature compensated to minimize drift, even under thermal shock conditions, enabling measurement of microwave power as low as one microwatt.
Key Features
- Frequency range: 10 MHz to 10 GHz
- Temperature-compensated thermistor for low drift
- Can measure microwave power as low as 1 microwatt
- Calibration factor and effective efficiency data at 12 frequencies
- NIST-traceable calibration at specified frequencies
- Maximum SWR: 1.75 (10-25 MHz), 1.30 (25 MHz-7 GHz), 1.50 (7-10 GHz)
- High RF match efficiency for accurate power measurements
Applications
- RF and microwave power measurement
- Power meter calibration and verification
- Microwave component testing
- Telecommunications system testing
