    Hi all,
    I am designing an automated (production) test system for an ISM band 2.4GHz digital transceiver board. I need to measure EVM on a DQPSK modulated signal and was thinking of using BB60. I know that it is possible through Spike (at least one of marketing pictures is showing that). But is it possible trough API or any other way under control of a test software?

    Regards

    Ramin,
    At this point we do not have a software interface to automate Spike’s EVM measurements, but it is something we have talked about, and may eventually add.
    Right now, you’d have to choose between reading the Spike software EVM manually, or using the API to capture I/Q data and something like Matlab or LabView (or other library) to compute EVM.
