CASSPER Measurment
(OP)
I'm doing precompliance testing and I need to convert 37dBuV from a 30kHz BW measurment to a 120kHz BW measurment. I think it is a 10Log(BW2/BW1) x 37dBuV? Or will I need to convert the 37dBuV to uV and then convert? This is a narrow band signal. 50 ohm system. Any help would be greatly appreciated.

I have found that to convert dBuV to uV it is:
(dBuV/20)Log(inv)= uV
Sound about right? Still looking for the BW conversion formula.
Thanks Jeff for the posts.

One should still sanity-check the answer.

If it's an RF signal your measuring, changing bandwidth of a measurement device won't change any signal measurement (just the accuracy a bit since Signal is the same and noise is larger).

dB is always 10logX (log in base 10 of course), if you're converting volts to power it's 20logVoltage, but converting dBuV to uv would still be 10^37/10 or 10^3.7 or 5011 uv, or 5 millivolts. Pretty small voltage.
