3. R GENERAL INFORMATION Introduction AT437C is a cost high performance microwave power meter for microwave power measurement It can measure the frequency range from 10MHz to 18GHz AT11802 It can measure power levels 0 1uW 100mW It s a portable design keeping in mind the bench and field service application AT437C power indicator from its power sensors and components The high performance and accuracy is obtained by the Power Sensor by chopper and by the linear correction circuit components Chopper is using high sensitivity low noise MOS FET switch components Series chopper Its main role is to transform the probe by the power of DC input signal modulation signal into equivalent exchanges and through the CPU to carry out the processing Microwave power meter have preamplifier as the high gain transistor and the high impedance Low barrier comprising operational amplifier with a gain amplifier exchanges about 600 hybrid amplifiers SYSTEM SPECIFICATIONS Frequency Range 10MHz 18 GHz Power Range 0 1uW 100mW Readout accuracy DATA 8 VSWR 1 25 Power Reference 50MHz 1 00mW 1 596 Display Resolution 0 01 dB Recorder output 0 1Voltage output Impedance 1KO Display W dBm dB Line Voltage Range 220VAC 10 50Hz 60Hz 10W Size 260mm L x250mm WD x110mm H Weight about 3 7 Kg ATTEN Electronics Co Ltd AT TEN INSTRUMENTS USER MANUAL AT437C POWER METER USER METHODS 3 1 NOTICE
