Hi All,

We have a requirement which suggests to use an input signal with 5dBm+/-2dB @50Ω.

I am confused as the tolerance unit is in bB while the actual value is in dBm.

How do I convert it to its voltage equivalent?

Thanks & Regards,
Naveen
 

In other words, the signal is 3 to 7 dBm. No milliwatt level reference needed for the +/- 2 dB variation.
