How to export wide spectrum for analysis in Spectrum Lab?

Hello,

I am trying to perform an analysis of the LNB's LO drift (prior to its modification) using any usable Oscar 100 NB beacon signal.
To do that I want to grab a 192[kHz] bandwidth and route it through virtual audio cable to the Spectrum Lab for analysis.
Is there a way in SDR Console to do that?

LNB I want to verify tend to drift more than 150[kHz] and I want to record its behavior during the day.

Thanks for any hints on the idea of performing such an analysis using SDR Console + Spectrum LAB.

I am not 100% sure this will do what you want, but an IQ output is available from SDR Console by using the output reserved for CW Skimmer via the VAC. Obviously you need to reserve an exclusive VAC for this output:

More information here (but you obviously only need the IQ routing part):

See attached picture to enable/select CW Skimmer output options.

Spectrum Lab expects audio in so unfortunately I/Q samples are not good.

Spectrum Lab can handle I-Q inputs - look through the Help documents

TBH dodn't found that earlier.
Will experiment with that.

Thanks!
