I'm in the market for a basic spectrum analyzer for amateur radio use, mainly tuning duplexers and checking antennas and feedline. I have read many reviews comparing the Rigol DSA 815 and the Siglent SSA 3021, and most say the Siglent is the better bang for the buck. Recently I've seen the price of the Rigol with TG drop below $1K and they now claim the RBW is 10Hz. Just wondering for the type of use that I'm going to use a SA for is the Siglent still considered a better bang for the buck at $400 more than the Rigol?
