Keysight N432A Thermistor Power Meter
The Keysight N432A is an automatic, self-balancing thermistor power meter for the use with temperature-compensated thermistor mount sensors. The device has a frequency range of 100 kHz to 18 GHz (sensor dependent), a dynamic range of -30 to +10 dBm, and a high accuracy of ≤0.2% ±0.5 µW.
- Thermistor power meter with frequency range 100 kHz to 18 GHz (sensor dependent).
- Dynamic range -30 to +10 dBm.
- Most accurate measurements with thermistor sensors for metrology applications.
- High accuracy (≤0.2% ±0.5 µW), excellent for 1 mW transfer calibration (with 478A-H75/H76).
- DC substitution measurement, traceable to the us NIST.
- Built-in 6.5 digit ADC eliminates the need of external DMM.
- Selectable bridge resistance (100/200/300/400 Ω).
- Digital color LCD.
- Remote interface flexibility (GPIB, USB, LXI-C).
