What is the uV/m level of a -37 dBmV signal leakage measurement at 127.2625 MHz?

To determine the uV/m level from a dBmV measurement, you first need to understand the relationship between the two. The term dBmV stands for decibels relative to 1 millivolt, and it is a logarithmic measure that indicates the voltage level of a signal. This can be converted into a linear voltage measurement in millivolts using the formula:

Voltage (in mV) = 10^(dBmV/20).

In this case, you have a -37 dBmV signal. Plugging it into the formula:

Voltage (in mV) = 10^(-37/20) = 10^(-1.85) ≈ 0.0142 mV.

To convert millivolts to microvolts (1 mV = 1000 µV), you multiply the result by 1000:

0.0142 mV * 1000 = 14.2 µV.

However, we also need to consider the transmission distance and the frequency, which can affect the received level when looking at signal strength in uV/m. The conversion from voltage measured in µV at a distance to a field strength measurement, uV/m, requires
