An error in the Probe unit when working with the Parametric EQ unit in SigmaStudio
In SigmaStudio there is a unit Parametric EQ
(Filters -> Second Order -> Double Precision -> Multichannel).
It has the ability to adjust the frequency response for 15 frequencies.
I have 3 chips: ADAU1702, ADAU1451, ADAU1467.
In chip 1702, the Probe unit together with the Parametric EQ unit displays all 15 frequencies
configured in the Paramtric EQ unit.
And in the microcircuits: ADAU1451, ADAU1467 the Probe unit together with the
Parametric EQ unit displays only 1 first frequency set in the Parametric EQ unit.
The remaining 14 frequencies on the frequency response curve in the PROBE unit
are not displayed. And physically all 15 frequencies set in the Parametric EQ unit work
correctly.How can this be correct?

Hello Diman,
What version of SigmaStudio are you using?
What operating system?
I just tried your project on my system and it works just fine. This was my result:
We did have some bugs recently associated with the Probe cell but I do not remember exactly what it was but it was fixed.
I am running Rev 4.1 and I tried it on Rev 3.17 which is the oldest I have on this machine. It worked well on both.
I am using Windows 10.

I am using Windows 7 and SigmaStudio Rev4.1. Probably this is just related to an old version of Windows.
Thank your Dave, for the answer!
