      Spurious Emissions and Intermodulation Distortions: Will Your Wireless Receiver Transmit Signals?

      Eric Hsu 2019.09.05

      Various combinations of signals in a transmitter and receiver can cause spurious signals. Spurious responses may be a spur from a LO, a harmonic of a power supply, distortion products, or a harmonic o

      How to Configure Wireless Receiver Dynamic Range Tests

      Eric Hsu 2019.08.25

      The most common wireless receiver test is receiver dynamic range which includes minimum input sensitivity, maximum input level, and channel noise. For different wireless standards, the definition of t

      Confronting Measurement Uncertainty in Signal Generation - Part 5: Phase Noise

      Eric Hsu 2019.05.30

      Signal generators produce the signals that you need ranging from simple to complex, and from pure to dirty, to test your design. You use signal generators as a local oscillator (LO), a golden transmit
