WebApr 15, 2024 · While the output range is about -0.2 V to 3.75 V (-74 dBm to +5 dBm), accuracy degrades for signals outside the specified range of 0.4 V to 3.7 V (-62 dBm to +4 dBm). The unit must be connected to a high-impedance load; it cannot drive a 50-ohm load. Measurement Speed theprizefinder closing soontheprizefinder.com reviewsAudio engineers use dynamic range to describe the ratio of the amplitude of the loudest possible undistorted signal to the noise floor, say of a microphone or loudspeaker. Dynamic range is therefore the signal-to-noise ratio (SNR) for the case where the signal is the loudest possible for the system.
