    Checking programming manual I could not find commands for:
    1. Setting auto option for RBW and VBW
    2. Setting spurious reject
    3. Average measurement.
    Spike is able to set these options.
    Please advise how could I do it.

    Dragan,
    1. I believe AUTO RBW/VBW is a function of Spike. If you like the RBW that Spike selects for your measurement, simply use this RBW, and set VBW = RBW.
    2. In the same saConfigSweepCoupling function where you set RBW, set Reject = true for spurious reject
    3. saConfigAcquisition is where you select average or min/max

    3. Under average measurements I had in mind a function which will be able to give me average measurement results based on selected number of sweeps (10 or 20 or any number).

    3.
    How do SA-124B and SA-44B provide average measurement results?
    Is it a function of Spike?

    Dragan,

    The API does not perform the sweep averaging you desire.

    To accomplish sweep averaging, you will need to acquire N sweeps and accumulate them into a single sweep (add bin-by-bin) and when finished divide each bin by N.

    Let me know if you have additional questions.

    Regards,
    Andrew
