• How to generate chirp (sweep signal) in AFG31000?

    Hi, 
    I need help with generating a chirp signal in AFG31000. I succeeded to generate up-chirp by choosing sweep mode, and frequency start that smaller than the frequency stop, and sweep time. but I don't understand how to create a down- chirp and up-down chirp / down-up chirp. 
    Can someone help and give me some guidance please?
    Thanks in advance!
