This 2075 Noise-Gain Analyzer is a programmable microprocessor-controlled, double conversion receiver designed specifically to make precise measurements of noise and gain characteristics of RF devices. The analyzer can be controlled using its front panel controls, or in remote mode by an external controller via an IEEE-488 GPIB. The specified input frequency range extends from 10 MHz-1850 MHz, but it is tunable and operable to 1900 MHz for RF measurements. More complex test configurations, requiring 1 or 2 stages of external down conversion, allow measurements of devices with output frequencies up to 65.535 GHz.
