Atec Agilent-432A User Manual

Agilent 432A Analog Power Meter

Data Sheet

The Agilent 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.

•

Power Range: 7 ranges with full­scale readings of 10, 30 100 and 300
µW 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

Calibration Factor Control: 13­position 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.

• Power Consumption: 115 to 230

Vac ± 10%, 50 to 400 Hz, 1.5 watts

• No thermoelectric error for high

accuracy over a wide dynamic range

• Optional long cables for measurment

convenience

• Meter: Taut-band suspension,

individually calibrated, mirror-backed
scales. Milliwatt scale more than 100
mm (4.25 in) long
