Which receiver mode is considered less accurate?

Null mode is considered less accurate because it focuses on minimizing the detected signal to establish a reference point for measurements instead of maximizing the signal. This approach can lead to less precise readings, particularly in complex environments where signals can fluctuate or be masked by noise. In contrast, other modes like peak mode and sweep mode actively seek to identify and quantify signal strength by focusing on the highest energy levels. Baseline mode can provide a clear reference by measuring against a known signal level, contributing to more reliable and accurate results. Overall, null mode's method of signal reduction inherently diminishes the accuracy of measurements compared to the other modes that emphasize signal detection and clarity.
