Waterfall is just a big square.

[Angelo Drone]

Hey, Just used REW for the first time. I'm at a loss as to why I cannot see what I'd expect to see as a normal waterfall graph. It just shows me a large square/cube. I've been researching, and I did calibrate my input/output but I cant figure out why it doesnt look like a normal waterfall?

Thanks and all help is appreciated.

Try these settings:

By the way, I have no idea what that problem at 110-120Hz is.

I'd guess fluorescent lights? Try turning off all the lights and measure again. Could be some other electric device too.

Ahh good thinking. I think I did have the LEDs on the back of my display on, and the ceiling fan on low speed. Nothing audible though, I thought. I won't worry about it.

The problem is probably SPL calibration, the response is all above the top of the graph. You can read the levels as you move the cursor on the SPL graph to see what they are. As an aside, the frequency axis on the waterfall is also set to a linear scale rather than log, click the Freq. Axis button to switch it to a log scale.
