HP 432A

High accuracy over a wide temperature range is featured on the 432A Power Meter. By measuring the output voltage of the thermistor bridges and computing the corresponding power, even higher accuracy of ?0.2%, ?0.5 ?W can be obtained. Accuracy can be maintained on even the most sensitive range because the error due to thermoelectric effect is reduced to a negligible level. The unit is an automatic, self-balancing power meter for use with temperature-compensated thermistor sensor.

Power Range: 7 Ranges with full-scale readings of 10, 30, 100, and 300 ?W, 1, 3, and 10 mW
Calibrated in dBm (-20 dBm to +10 dBm)
