Start with the installed cascade. List loss ahead of the first active stage, preselector band and rejection, LNA gain and noise, switch or attenuator states, receiver input range and conversion or ADC full scale. Evaluate minimum and maximum tolerances across frequency and temperature; a nominal gain state can hide both poor sensitivity and insufficient headroom.
For blocker and IP3 tests, state frequencies, spacing, tone or modulation, bandwidth, levels, gain state, RBW, detector, temperature and measurement plane. Verify the source and combiner residuals before connecting the receiver so test-bench intermodulation is not reported as receiver behavior. Include close-in reciprocal-mixing and image cases where they matter.
Acceptance should limit noise-floor rise, desensitization, intermodulation, false lines, amplitude error and unavailable time while confirming overload indication and recovery. More attenuation may protect linearity but raise the detectable floor; more LNA gain may improve cascaded noise but reduce strong-signal margin. The selected state must satisfy both ends of the declared environment.
