Objet : [Elecraft] Signal tracing with a scope
Ok..... I see that on my oscilloscope I can have the "True RMS readout
(Vrms ac)".... is it the same thing as we get when we take a mesure
using the RF probe that we built in the K2 kit ???
The RF probe that we built in the kit should convert RF into Vrms when
we set the DMM in DC 20V-30V.... and in the "Signal tracing" chapter,
we can take many readouts of certain part of the K2. With the RF probe
using the DMM, I have correct values in the range that they mentioned,
but using my scope for the same reading, the values are not same, even
sometime not near of.
Maybe I missed something or maybe I mixed values and unit used... but
"True RMS readout Vrms ac" is not the same as we get using the RF probe
with a DMM ???
Or is there any conversion or formula I could use to have the correct
answer using my scope ???
Thanks for your patience !!!
