2. Receiver dynamic range is calculated as the difference between maximum 

receiver input level and receiver’s noise floor. 

System dynamic range applies to transmission measurements only, since 

reflection measurements are limited by directivity.

Noise floor is specified as the mean trace noise at specified CW frequencies. 

A signal at this level would have a signal to noise ratio of 3 dB. Noise floor is

measured with test ports terminated in loads, response and isolation calibration,

15 Hz IF bandwidth, 10 dB source power, and no averaging.

3. Measured at 0 dBm, excluding frequency response, transmission measurement.
