Measuring in dBA in RTA

[crallen]

Hi all, is it possible to measure in dBA weighting in the RTA? I can see dBC and others but cannot see dBA?

thanks!

What version are you using? The V5.20 builds show levels unweighted, C-weighted and A-weighted.

Hi, Just downloaded and installed the latest version RC14c but still cannot see dBA, attached pic

Oh saw that. I assumed as there was the dBC scale option I could select dBA too, but perhaps I'm assuming wrongly.

thanks!

The dBc Y axis option is dB relative to the carrier, it normalises to the peak. From the help:

A dBc Y axis option is offered which places the peak level of the input at 0 dBc, or places the peak of the fundamental at 0 dBc when the distortion panel is active.

OK understood, thank you for the clarification!
