    Hello Andrew,
    thanks for the prompt answer, let me attach an image to better explain.
    As you can see in the image, I’ve done these steps:
    – Run a peak sweep
    – In “Peak Table”, clicked scan for spuries
    – In the meter readings, all spuries have been scanned. One of these, 480.957031 kHz has been tested with the Meter settings tab, but as you can see, the Quasi-Pk table in “Meter readings” gives 31.53 dBuV, while the QP detector of meter settings gives 46.66 dBuV. This mismatch is always present.
    What is the cause of this mismatch?

    Hello,
    I’ve just purchased the BB60D, mainly for EMC precompliance purposes.
    As other forum community told, is there a way to test the Quasi peak measurement in an automatic way? From what I’ve seen, you can tell the device in the “Peak Table” to scan for spuries, but these peaks are much lower than the data calculated in the Meter tab, where the three bars with peak, QP and average are displayed.
    Is there a way to press a button and then get QP and AVG waveform be calculated? Also is there a way to display two waveforms, one with QP measurement (or Peak and QP for failing spurs) and another with AVG measurement, each with their own limits?
    Thanks,
    Mattia Berton
