 No, you can't fashion a high pass filter with the BFD.
They both show usable output to about 15Hz. The signal below that is noise. REW tends to compensate down low since you have the C-Weight box checked (as the C-Weight graph drops, the noise signal rises. Uncheck it, since you have a cal file loaded.
It would help out if you used the standard axis of vertical 45dB-105dB and horizontal 15Hz-200Hz. It makes it easier for everyone to read. Also uncheck the soundcard cal and meter cal to remove the lines from the graph.

Sorry about the axises. I thought John had set the defaults in v 4.0 to suit the forum. I didn't realise I had to limit the axises for sub readings.
I also thought the Cal file allowed for the C-weighting. If I uncheck the C-Weight box, should I also turn C-Weight off on the meter?
