Easy Explanation of Units Used in EMC Measurements (dBm / dBuV )

Units used in EMC test and measurement such as dBm, dBuV etc. can be confusing. Using numerical examples, in this video Dr Ali Shirsavar from Biricha Digital explains these units in simple terms + shows a practical example using real life measurement.

Very nice explaination. It will be reallly helpful if you can explain design consideration to qualify emi/emc tests in your lucid and easy to understand way

Hi, Thank you for your clear explanation. I have a question regarding the power you calculated (across the 50ohm). How is this number related to the signal you are generating at 15 MHz, and showing the exact 13dbm in the spectrum analyzer. In other words, how from the signal itself the power is 13dbm, over what period? would you mind explaining a graphical representation of the original signal that generates 13dbm power? Thank you.

Nice way to show new product i guess? Bode 500, nice jacks!

If only you had taught at my University, they would still have an engineering department left.
