Hi all, looking to buy my first waveform generator, and was wondering how the Owon products stack up against Siglent products. Only have about $300.00, or so to spend. Been looking at the Owon Ag1022F, and Siglent SDG810. Using this primarily to test audio amplifiers, and filter testing. Had ordered the Owon AG1012, but then realized it did not have the modulation functions. Sent it back, and now decided to try the versions that include modulation, and possble other products. Thanks.
