Validate RF with Practical Analog Source Setups

When receiver behavior, RSSI response, or amplifier performance needs to be characterized, the signal source can affect how test conditions are created and repeated. This application note reviews common RF device test setups using compact analog signal generators, including blocker and interferer testing, power calibration, LO and clock substitution, and amplifier gain, compression, and intermodulation testing. With practical setup examples and documented source specifications, you’ll see how output power range, signal purity, and switching speed apply to RF device characterization across R&D, manufacturing, and field test workflows.
