Hello,
I need to convert a broadband noise spectrum from the dB as defined in your software into V^2/Hz.
How do i do this?
Thanks,
Jason |

Hello,
You will need to change the spectrum screen options.
Go to the settings menu and choose options. Now select Y axis and change from dB to volts RMS.
Best regards,
Michael |

Hello
I have the same question about converting power spectral density from Db to V per root Hertz
I can see (I think) how to convert from Db to V (using your definition of reference voltage) - or changing the display to V as you say - but I'm wondering abot the frequency scale - is it really per root Hertz or is it per sample (in which case the unit would change with frequency range and number of samples)
To be honest, if it is a power spectral density then the software should give it in Db (or V) per something (I think ?) |
