Plain-language answer: Receiver dynamic range is the span between the weakest usable signal and a stronger signal or distortion limit under a stated test.
Why the definition matters
Several dynamic-range definitions exist, including blocking and intermodulation tests, so one headline value does not describe all crowded-band behavior.
Use the number correctly
Compare the same test spacing, bandwidth, preamp setting, frequency, and standard; consider the antenna environment where the receiver will operate.
The common mistake
Comparing dynamic-range numbers measured with different signal spacing and preamp settings.
Measurement and safety boundary
Keep reference units, bandwidth, detector, direction, averaging, and test conditions attached to every number. Current regulator requirements and the complete installed system control RF-exposure compliance.
