Thank you all for the help!
Besides NANOVNA use of the generator I have some other projects in my
wishlist. So I am looking for the generator to have a +/-2dB power level
accuracy and +/-1dB stability for up to 500MHz. Power level say -40dBm to 0dBm
max would suffice for ham projects. Furthermore a CW sinusoid carrier would be
great, a clean one as well. All within the radio amateur budget, not looking
for a high end professional lab bench top equipment. For reference keep in
mind RF EXPLORER Combo product.
I suggest the TinySA for your needs. It has a range of -8 to -76 dBm with 1 db steps up to 350 MHz in low frequency output mode. In high output frequency mode it goes from 240 to 960 MHz. with -34 dB to +16 db but in very large steps so you need an external programmable attenuator ( I bought one for $40 USD on eBay). The output is a sine wave and it can do frequency sweeping. You have limited modulation features as well. It's primary function is as a spectrum analyzer and it does a good job at that. Price is around $50 USD which is a bargain.
A new version (with better ESD protection) will be released in early May. You can get express delivery from the manufacturer's store on Ali Express or wait until the distributors get stock.
