Noise measurement.

The strength of a received tag signal is affected by a number of factors, for example tag power level (low or high), distance from receiver, interference in the water, and attenuation due to water conditions. For a given tag signal strength, placing a receiver in a location where there is less noise will help to improve the signal-to-noise ratio. VEMCO’s new VR2AR and VR2Tx receivers have the ability to record average noise levels as well as min/max noise levels for a specified time period. (See user manuals for instructions on noise logging). If noise logging reveals that a deployment location may be unsuitable, then a comparison of noise levels at other deployment locations can be performed, and the least noisy location can be chosen.
