What are suggestions for "affordable" high frequency signal generators? With "high frequency" I don't really mean the HF band, but around 500 MHz at least, but preferably up to 1 GHz or much more. 5-6 GHz would be fantastic, but I realize that may be entering difficult territory. I'm a hobbyist and don't have lab grade requirements for e.g. phase noise, but the generators I can find on eBay are often easily multiple times the price of even my Spectrum Analyzer and VNA. I sometimes see that there are some cheap boards on eBay or AliExpress, any experience or recommendations regarding those? |

Well you already have a SG in your SA TG if you use it in zero span mode. ;) |
| bayjelly:
Right, tautech. I know that and even used that, but then my SA, which I really want to use in those sort of endeavors, is stuck in zero span mode at that particular frequency. :D Not super good if you want to use that signal as, say, the LO input to a mixer! |

Please define affordable. $2.5K will get you a 2.1 GHz modern proper RF gen but if you need more AWG like capability/features start at $1.5k and go up ! :scared: Some models to investigate: SDG6000X SDG7000A SSG3000X SSG5000X |

Try the used instrument market, HP/Agilent, Marconi, Philips and a load of others. Look on ebay, but also check used test equipment dealers. Phone a few. They usually offer some short guarantee, and sometimes have reasonable prices. |
