That's very strange, I'm using Foxit reader myself (free version), and I checked the attachment before posting.
My version was 2.3 build 3201, I've just updated to 3.1.2.1013 and rechecked that that's OK as well.

I think i found something quite surprising. I don't want to post it now, because I'm not sure if I did everything right, but let me just say that the easiest explanation may also be the correct one, this time. :o

I have a RIGOL DS1052E to and I measured the frequency response.

Looks for me like an analog Cauerfilter with a low order...

Awesome work!
At which point in the circuit did you measure the frequency response?

Dave.

This was only a quick Test with a Function Generator and the build-in measurement function of the Oscilloscope. I took samples in 1MHz steps and filtered the Results with a digital Lowpass.

I haven't opened it yet, but I'll do it next week when I have access to the Lab at the University.

Thanks to Dave and you guys I'm now about $380 (plus customs fees) poorer, just ordered myself a DS1052E :) Now lets get it modded to 100MHz (not that I have any use for such high bandwidth right now... :P)!

I haven't bought yet, but I saved this seller. He sells Rigols a bit more expensive than Chinese, but has a 100% positive feedback. I wouldn't risk buying from someone with 99% (which basically means they get over a 100 negatives every six months (example)).

Yes, that is essentially the same guy as this one where I bought mine few days ago  ;D

So he is selling for $426 as opposed to $386 for the cheapest. 

For fifty dollars more he's offering a US warranty.  Do you know the specifics of a 'US Warranty'?  Does that mean there might be a US service location?

don't quote me, but often that means you ship it back to them, then they send it in for warranty. it also usually means you pay for the international shipping both ways, it can be a headache. Check on Rigol's "Grey" import rules, they might be more relaxed, since its all price control nonsense anyway.

funnily enough i was looking at that aidetech seller last nite and their SMD component packs.

I got mine from a seller named "happyseeds" in china, he was fairly reasonable and cared that much about feedback that I got a £ 50 refund from him,

I got mine from HappySeeds as well. I believe I was his first customer for this scope.

Count another one for happyseeds!

Just bought mine $395 US.  T-minus 7 days!

Christmas comes early.   Thanks Dave, and everyone for all the advice.  I wonder what kind of margin happyseeds is getting?

probably a big one as I paid £ 239 for mine and left negative feedback for the noise it has (ok maybe I jumped the gun but...) he got in touch and said he would offer me the chance to return it at his cost if I changed the feedback. I looked up the postage costs and found them to be 75-85 pounds so emailed him back and told him that as i needed a scope and could cope with this but for having better value for money and suggested a £ 50 refund. He immediately complied, so i actually got it for £ 189 and he paid the postage which I bet was maybe another £ 30-50 ? so they must be real cheaply made (and hence the lack of decent shielding on the psu) and he must buy them real cheap for like £ 100-120

I have the DS1052E firmware and would like to compare.

In what format? Could you please share it with us? ::)

http://www.mightyohm.com/blog/2009/11/agilent-dso1000-firmware-update-confirms-rigol-connection/

there is some new information about the agilent - rigol connection.
Wonder if it would be possible to mod the firmware, for new colors, new ways of manipulating data etc

Cheers, Lovro

Good chance, as I believe the hardware is identical, or it used to be in the older Agilent/Rigol scopes.

any advantages to using agilant firmware over rigols and any risk of ruining the scope ? someone willing to try this ?

My new Rigol finally found its way home :)

Here is my 'lab'.  My theme is 'nothing can stay on the bench'

And yes that Harbor Freight multimeter is going in the trash soon.  Its the next thing to get an upgrade.  Maybe looking at a Fluke 18B or other (any suggestions for <= $80 US?).  

15 days to deliver it from Nanning, PRC.  Did anyone buy those gimmick toys from comic books when they were young?  (i.e. Sea Monkeys, garlic chewing gum, etc.)  They always were 2 to 4 weeks delivery.  About the same as waiting for the DS1052E to arrive.

Hey Dave,  can you sign my Oscilloscope!?!   LOL, if you send me your digitized signature, I'll print it right out and paste it on -  yes, I'm a geeky enough to be serious.  ;D

V

Addition:  What was I thinking??  I can make a nice project out of that Cen-Tech.

As a spare toolbox meter i picked up a protec 6300 for $50 at frys ( it was either on sale or marked incorrectly) the 6100 is $49

http://www.frys.com/product/5285857?site=sr:SEARCH:MAIN_RSLT_PG

Not as good as my fluke 88, its not as responsive but it has a great feature set, you should be able to find it cheaper than frys current USD $79.

I've had no issues with it, other than the response time, but i've yet to find a cheap digital meter with a fluke like response time.
