The 432B Digital Power Meter uses four power ranges with full-scale readings of 10 and 100 MicroW, and 1 and 10 mW. Noise is less than 0.25% of full scale peak (typical). Meter offers three digits with one digit overrange.
(Requires thermistor mount.)
The 8478B provides high efficiency and good radio frequency (RF) match are characteristic of the 8478B coaxial thermistor mounts. Used in conjunction with the 432A power meter they provide high accuracy even in routine power measurements. These thermistor mounts are temperature compensated for low drift, even in the presence of thermal shocks, permitting measurement of microwave power as low as one microwatt.
