    Impedance Measurement timing offset

    The results look good and are very consistent so I think I am just going to not worry about it. At some point if I get an opportunity to try another soundcard I will see if that makes a difference. I have a switch wired to remove the attenuation and zener clamp so I will also try and run it off...

    Impedance Measurement timing offset

    I built a ARTA measurement box so I can measure impedance and T/S parameters in REW. I am using the box with an external amplifier and a Steinberg UR22C soundcard. Everything seems to be working well however every time I do my open circuit calibration I get this: It doesn't seem to depend o...

    That did the trick. Weird because I have absolutely no idea what I am doing and I didn't change those values (didn't even know they existed). Very strange but I appreciate your help.

    This is at its default setting for the program. I haven't messed with it. It appears to be at 5ms. I tried addiing a couple of screenshots to demonstrate this but the forum software is marking this as spam for some reason and won't allow me to post. Edit: I was able to add them after...

    I know this has to be something simple but I have been at this all day and cannot figure it out. I am using the latest edition of REW beta on windows 10. I am trying to take some measurements of some subwoofers I just built. I have my microphone selected, calibration file loaded, and am getting...
