Hi all,
I'm just starting to get into frequency response measurement, and have started to do some things with REW. I ran a sweep in REW and compared it to a "by-hand" excel response graph, and the REW graph was ~6dB louder at every frequency. To do the "by-hand" graph, I used the REW frequency generator at 1dB increments from 16Hz to 80Hz. It was basically the same as the REW graph, it was just ~6dB lower. I was using the same settings/calibrations/volumes for both measurements.
I have a RS digital SPL meter and a Behringer UCA202 USB sound card hooked up to my laptop.
I was going to start posting about suggestions to correct my frequency response, but I wanted to get this straightened out before I start posting about that.
Thanks for any and all help.
