Graph Panel Help

[ssalyer007]

Hello everyone! Just getting started with this amazing software and running into an issue with how measurements are showing in the graphs.
I've watched some tutorials about setup and calibration and feel pretty confident I've gotten that right.

Just as a learning experiment I'm measuring the response of a simple audio preamplifier. The sweep goes well and I get a nice reading in the All SPL graph. Problem is all the other graphs with the exception of the SPL and Phase display nothing.

SPL and Phase doesn't look like how it's shown in the Graphs Panel Help Section.

Here's what I'm seeing. Any help would be greatly appreciated. Really hoping to find the distortion plots

Here's the only other graph with visible data. All SPL

A pre-amp only? Are you doing this va a loopback connection?

Regardless, change the verticle scale (left side) to 45-105 dB.

Regards,

Thanks for the response, Wayne
Yes just a preamp.

You made a multi-input measurement with nothing on the second input, that result is just the RMS average. Untick the multi-input option on the soundcard preferences or via the dialog shown when you click the input configuration button on the measure dialog. When you do need multiple inputs you can choose the option to save individual measurements for each input as well as the average, or omit the average.
