Re: Continuum mode

Typo.

 

Given:

  • Center frequency & bandwidth with have a count of FFT bins = X (values in dBm)
  • Resolution bandwidth = Y Hz

 

What’s the formula for the actual continuum value when these X bins are used?

So,

 

Given:

  • Center frequency & bandwidth è Count of FFT bins = X (values in dBm)
  • Resolution bandwidth = Y Hz

 

What’s the formula for the actual continuum value when these X bins are used?

Hello Simon, I really appreciate you adding this feature. I do have SpectraVue and an SDR-IP and in the past like Charles I used SDRC with Perseus and the IQ outputs as inputs for SpectraVue. Very cumbersome!

 

Let’s get it working and then I have some other ideas.

 

This will be really useful.

Hi,

 

That’s fine. I can get almost all work done, then there’s fine tuning. I think a docking window like the Signal History is the correct solution.

Hi.
Here is an early message (May 2014) with an tentative short-spec for the Continuum Mode:
