  "account": "This white paper provides guidance for RF and microwave engineers and technicians on utilizing compact analog signal generators to perform essential testing tasks. The article covers the measurement of amplifier gain and gain compression, including the P1dB point which signifies the shift from linear operation to saturation. It also explains how two-tone intermodulation distortion testing can identify unwanted signal products created by amplifier nonlinearities, and why third-order intercept (IP3) is utilized to compare amplifier linearity. The document outlines procedures for testing receiver performance under blocker and interferer conditions, employing high output power and rapid switching speed to mirror real-world interference. Additionally, it discusses the importance of power calibration and RSSI testing that rely on precise, repeatable signal sources across various frequency channels and bands. Lastly, the paper highlights how signal generators can serve as replacements for local oscillator and clock subsystems during early-stage receiver development, prior to the availability of final circuit prototypes.",
  "summary": "This White Paper shows RF and microwave engineers and technicians how compact analog signal generators support core amplifier and receiver test tasks, from gain and distortion measurements to blocker rejection, power calibration, and local oscillator substitution. What you will learn about: How to measure amplifier gain and gain compression, including the P1dB point that marks the transition from…",
