If they differ from your KS measurements, how would you rate that? Good, bad, or just different? I find such discussions very interesting.
The FPL1000 has a phase noise of -105dBc (-108dBc typ.) at 1GHz/10kHz. At 1Mhz/100Hz it is better at -124dBc and at 1MHz/1kHz at around -132dBc. That's why I made my measurement at 1MHz.
At 10MHz and 100Hz offset it should be around -115 to -120dBc, that can only be estimated from the data sheet. These are values from the data sheet and are therefore better than the Siglent SAs.
Don't confuse the FPL1000 with the FPC1500, which has already been discussed here in the forum. I would also like an even better phase noise, but I didn't want to sell my house for an SA
I personally think the SDG6022X is very good for the price. A comparison with KS using specific examples would be nice.
