Ignacio: I am sorry you are having a problem with it. I just put the code on my signal generator (8640B). I tested every buffer size, audio and dsp, with and without polyphase display. The results were identical to the tenth dB on the meter and the same pixel on the display. Are you using the Blkharris window?
Setup->DSP->Window == Blkharris Then recalibrate. 73's Bob Ignacio Cembreros wrote: > Ignacio Cembreros escribió: > >>> Robert McGwier wrote: >>> >>> >>> >>>> It does.
