Principais recursos e especificações

  • Power Range: 7 ranges with full-scale readings of 10, 30 100 and 300 uW 1, 3 and 10 mW; also calibrated in dBm from -20 dBm to +10 dBm full scale in 5 dB steps
  • Noise: Less than 0.25% of full scale peak (typical)
  • Response Time: At recorder output, 35 ms time constant (typical)
  • Fine Zero: Automatic, operated by front-panel switch
  • Zero Carryover: Less than 0.50% of full scale when zeroed on most sensitive range
  • Meter: Taut-band suspension, individually calibrated, mirror-backed scales. Milliwatt scale more than 100 mm (4.25 in) long
  • Calibration Factor Control: 13-position switch normalizes meter reading to account for thermistor sensor calibration factor. Range 100% to 88% in 1% steps
  • Thermistor Sensor: Thermistor sensors are required for operation of the 432A.

Descrição

The 432A analog power meter will be discontinued on June 1, 2011. The replacement product will be the N432A Thermistor Power Meter

The Keysight 432A provides high accuracy over a wide temperature range. By measuring the output voltage of the thermistor bridges and computing the corresponding power, even higher accuracy of ±0.2 percent ±0.5 microW 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.
