Model AT-211 B is an Automatic Self Balancing Power Meter - 0-18 GHz. It measures RF Power with the help of temperature compensated Thermistor Mount from 1 0;UW to 1 OmW full scale with 1 % accuracy from 10 MHz to 40 GHz (depend upon type of Thermistor Mount)
-
With calibration factor control switch, AT-21 IB normalizes the Power Meter reading to compensate the efficiency of used Thermistor Mount.
-
AT-21 IB has provision for substitution measurements and Power Meter calibration. Output is provided for recorder or Digital Voltmeter readout.
