So I would not use this bin as reference level. |

I´ll repeat the measure... ;) |

Am I just about to... Quick question: It was interpolated 20-fold according to the entered formula. Before I set the acquisition mode to average, 40GSa/s came out, see the pictures before the last one. Now that I have last set to average 32, it is 400GSa/s (see last picture) is that correct ? |

OK, finished for today... ;) This time I used the cursors for finding the -3dB frequency, that should be "allowed" for this. 1.5Ghz span and 5dB/div settings, 515Mhz.... --- Quote ---Btw, I don't know where this comes from, but the 0.5 dB drop in the DC bin doesn't look right either. --- End quote --- I´ve "zoomed in" using a span of 500Mhz, when the Delta f is a bin (?), than it "happens" in exact the first one, 0Hz..24.41Mhz. From 24.41(24.5 marked)Mhz down to 0 it´s -3dB. (possibility to change the axis-labeling left/right would be very, very useful for a better viewing.) |
