A friend went back Taiwan bring me back a Hantek DSO5102B in his backpack, about CAD$450 from hantek distributor. Yep, if u got friend in china, then u can have it about $400 or less.
Open up, every piece made by tekway, only little diff on firmware. Has reserved fan connector holes on board and fan bracket, but maybe no need a fan, as let it continue work 4-5 hours highest temp was 43 celsius degree on PSU. Probes come woth it are 150Mhz, yep, I have better, it's not a matter for me.
Before I open it up, I had a feeling that this one is 200Mhz ready, as the SN lable on the back of machine is T 1G/200M 00xxxx, but firmware show T 1G/100M 00xxxx. Yep after I open it up it is 200Mhz ready--44A(280) and 330 risistors on board.
Sadlly, firmware is 2.06.02(101108.0), that means I may not update it just by usb without lie to DSO.
Havn't play it too much, but will do.
Also thanks Tinhead, I almost pull the trigger on Atten ADS1102CAL right before I saw this post.
Btw I think the front shell and knobs color should be gray instead irovy, as time and heat will let irovy turns to yellowish.
