In this episode Shahriar investigates a malfunctioning Agilent PSD Vector Signal Generator. These (expensive) instruments offer very good spectral purity as well as builtin vector signal generation which makes them ideal for testing and characterizing advances wireless systems. The instrument does not produce any output signal while also generating no error signals. The block diagram of the instrument is presented accompanied by detailed testing and teardown to finally locate and correct the problem.
