Atec Agilent-432A - 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 full-
scale 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
• 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.
• 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
• 1 year standard warranty
