The HP Agilent N4002A 26.5 GHz Noise Source measures noise figures reliable and accurately up to 30 dB from 10 MHz to 26.5 GHz. It featuers an APC 3.5 connector, electronic storage of Excess Noise Ratio(ENR) calibration data decreases the opportunity for user error, automatic download of ENR data to the NFA speeds overall set-up time, and temperature compensation improves measurement accuracy leading to tighter specification of device performance.
