Keysight-Agilent 8970A-H18

The 8970A Noise Figure Meter takes the mystery out of noise figure measurements. A microprocessor is used to make the myriad calculations and corrections necessary for truly accurate, convenient and flexible noise figure measurements. RF and microwave (with external local oscillator, sold separately) measurements from 10MHz to at least 26.5GHz are equally simple; any IF between 10 and 1500MHz may be used. Displays both noise figure and gain, calibrated display on scope or recorder, and powerful special function enhancements. The ENR calibration table of the noise source may be stored in the 8970A, and a properly interpolated value is automatically used at each frequency. H18 = 1.8GHz Upper Frequency
