SIGLENT SSA3032X input related spurious
« on: November 22, 2017, 09:01:28 PM »
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.

Please don't double post, it severely irritates people.
The ĀµCurrent has landed in Europe and now also selling Probe Master probes: http://www.simonselectronics.co.uk New stock now in.
