SIGNAL GENERATOR 10KHz-65MHz
THE HP 606A IS A GENERAL PURPOSE SIGNAL GENERATOR WITH A FREQUENCY RANGE OF 50 KHZ TO 65MHZ. THE INSTRUMENT HAS A DIRECT READING FREQUENCY DIAL CALIBRATED TO AN ACCURACY OF 1%. OUTPUT IS HELD CONSTANT WITHIN + OR - 1 DB AND IS CONTINUOUSLY ADJUSTABLE FROM .01 MICROVOLT TO 3 VOLTS INTO A 50 OHM RESISTIVE LOAD. AN INTERNAL CRYSTAL CALIBRATOR PROVIDES CHECK POINTS AT 100KHZ AND 1MHZ INTERVALS WITH AN ERROR OF LESS THAN 0.01%. A FRONT PANEL METER ACCURATELY INDICATES THE PERCENT AMPLITUDE MODULATION FOR FREQUENCIES WITHIN THE MODULATION FOR FREQUENCIES WITHIN THE MODULATION BANDWIDTH OF THE SIGNAL GENERATOR.
THE 606A HAS A HIGHLY REFINED AMPLITUDE MODULATION SYSTEM WHICH ALLOWS MODULATION UP TO 90% WITH LOW DISTORTION AND INCIDENTAL FM. THIS FEATURE MAKES POSSIBLE PRECISION DISTORTION CHECKS OF RECEIVERS FROM ANTENNA TO OUTPUT. THE INSRUMENT CAN BE INTERNALLY MODULATED @ 400 OR 1000HZ. IT CAN BE EXTERNALLY MODULATED FROM DC TO 20KHZ OR MORE, DEPENDING ON RF FREQUENCY IN USE. COMPLEX WAVEFORMS, SQUARE WAVES AND DC VOLTAGES MAY BE USED TO MODULATED THE HP 606A FOR TESTING AND EVALUATING FILTERS, NETWORKS, AMPLIFIERS AND RECEIVERS.
