Hi Ron,

I resell them in Italy. My experience is that ATTEN items come from 
many different factories and design lines, and the quality is quite 
different between products. The AT5xxx spectrum analyzers are the old 
Hameg heritage; they were designed in Germany 15 years ago. The 
oscilloscopes are completely different, and they perform very well. 
We had no warranty returns so far on the ADS11xx series.
In particular, the software is vey good, and the processor is 
powerful; very live trace display, and no delays doing math 
operations. If you are an experienced user, and want to compare them 
to an old fashioned Tek 2445B, you will find that the Tek trigger is 
superior in accuracy. But so was the original Tek price!
