A friendof mine has a Hameg 3GHz SA with TG and compared that before buying with a Rigol. So he knows both. He said the Rigol was not bad but the Hameg was a whole class better.
I have a Tek 2710 and 2712. They are 9kHz to 1800 MHz. I love them. Not as much noise as the Rigol 1,5GHz and the great thing about them is they are hybrids. You can use them analog and digital. Store 4 traces, waterfall and and several marker options.
Two of my vna's have a SA function but that is rather low performance, noisefloor is -100dBm or I must be very patience and choose a very narrow filter then I can get 125 dBm . Build two SA's myself (0-500 MHz) and have owned several others (like a 1 GHz portable digital TekTek and an analog HP)
When I'm alinging a transmitter or oscillato etc, I use it in analog mode because the speed. I wanty to peak a signal reakl time and not turn a bit, wait 2 seconds and then see I have turned to far.
We should do a compare in a topic. Just show the same screenshots for every SA, for instance a -30dBm 100 MHz signal and then something like a 100 kHz, 10 kHz and 1 kHz resolution bandthwidth and also the most narrow RBW available that will show how low the noisefloor for several SA's is. The add data like sweeptime etc.
