Recently received new SSA3032X and extremely pleased with performance and would highly recommend.
Thing is the only performance issue I've found is a bit annoying and well outside Siglent input related spurious spec of -65dBC.
Am waiting on Siglent feedback response.
Wondering if anyone else has noticed this input related spurious ...
An input related spur appears 60.0MHz below the wanted input signal at -57.5dBC.
The spur appears across the whole input range to 3GHz and is very consistent.
The spur is not changed by input level from -30dBm down, that is it's always -57dBC.
No change in spur dBC with any parameter settings.
Not a show stopper for me I guess and Siglent -65dBC spec would be exceptional for a budget instrument if it met it ;).
Have done sanity checks with other signal sources and analyser, it's the Siglent for sure.
Wonder what other SSA3000 instruments out there do on this one?
Cheers, Martyn.
