Rigol DS1052E Ep#37

[Veramacor]

Great suggestion Charliex,

That almost exactly hits the budget constraint.  I'll check the Protec out.

I bought the Centec from HF on sale as well.  $3.99!  That's less than some of the project boxes Radio shack are selling.  Now I have a project box with built in LCD screen and selector switch...

[charliex]

I also have the PROTEK B940 bench DMM, but i couldn't recommend it to anyone. The selector switch is hard to turn, the LCD is hard to read and looks like it has the old problem of LCD's with that rubbery contact strip that doesn't, so you get some of the sections lighter than others and its hard to read at angles.

For some reason the backlight is a momentary on, as opposed to a latch. I never understand that one, especially on a mains powered device (though it can be powered by a 9V battery). I like the backlight on, same as the audible beep for continuity tests.

If the device doesn't have the faculties to store a boolean flag between sessions, a simple latched switch solves that.

I actually ordered a Rigol from HappySeeds through ebay, but the day after I bought it all his auctions and his account were shut down by ebay for some sort of violation, though I think he might be back on now. He never sent me the scope and did not respond to my communications, so ebay refunded my money. It seemed that all the cheap Rigols were taken off ebay at the same time.

This was actually the second problem in a row for me for buying a scope through ebay where ebay had to refund my money. The first scope was an Owon that I am now glad never arrived since I can now see they are clearly inferior to the Rigols. I have now ordered a Rigol from a US vendor for $512 delivered. Not the best price, but after two months of trying to get a scope I gave up on getting a bargain and this scope is due to arrive in two days. I found overseas vendors still selling them for about $100 less, but I didn't want to risk it without at least the protections offered by ebay.

oh happyseeds is back or is it another seller with the same name ? maybe he was just suspended ?

[Zapro]

Wow, i saw this DS1052E scope at EEvblog 14 days ago, and realised that i just NEEDED to have it.

Arrived today, 4 days transit from UK (i'm located in Denmark)

Bought it on ebay. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=260540024931

I just LOVE it, it's brilliantly!!!
Very good value for money.

Anyway, while looking around the net, i realised that RIGOL not only deliver OEM parts for Agilent (as discussed here) they make other brands entry level models too, see this for example:

http://frankie.eefocus.com/stupid/blog/08-09/156839_4013b.html

Lecroy and ATTEN, both using RIGOL parts for sure. The buttons on the front panel is just put in a different manner.

Seeing this can only give RIGOL more credibility anyway.

Another thing, can anyone explain to me what SinX/X feature is for ? The manual does not describe it in detail, nor have i ever heard of it 

Regards,
Per.

[Zapro]

My new Rigol finally found its way home

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

WOW, i love that bench and all that order !!!

I'm a bit sceptical about the possibility of LeCroy outsourcing their scopes. Could be just a knock-off. Anyone else now anything about this?

[charliex]

Lecroy has outsourced for years. They've recently announced (this month) that they're starting to reverse that and bring more of the manufacturing inhouse.

The wavejet/surfer 4000 is made by iwatsu, waverunner 6000a,xi,wavesurfer xs are made by plexus. I don't know who makes the waveace. wavemaster, waveexpert, and wavepro were inhouse, at least they were.

Sin x/x is a novel way to "join the dots". This has been discussed here, in the first post of that topic.

As someone else said, it's a nicer way to "join the dots" on the display. But not only that, it can be proven mathematically that it will reproduce the input waveform *precisely* from only (if IIRC) 4 samples per cycle. Taking into account the front end bandwidth filter that is.

Here is an Agilent article on it:

Hello Everyone



In regards to the question about Logic analyzers, I asked Rigol this question for another customer and was told that a  logic analyzer can not be added on seperately.

 Do you already own a Rigol scope without logic analyzer or do you just want a  scope which you could be able to add a logic analyzer to in the future?

[Ferroto]

Hello Everyone,

 We are the Uk distributors for Rigol.  All products purchased thru us are locally supported here in  the UK.  If you'd like any Rigol products or anything else please feel free to contact me direct.

Depart you evil demons of SPAM!!!!!!

[Joy at MCS]

 I don't see it as Spam.

 I was answering  a question which was posted awhile ago about  regarding if the Logic Analyzer could be added to the Rigol 1052E.
Ie this post:
This post is related to Episode #37.
Let's start discussion about possibility to extend functionality of Rigol DS1052E.
Can we extend analog bandwidth to 100 Mhz?
Can we add Logic analyser?
Can we modify firmware?

What I didn't realize at the time was that this was an older post I was replying to. Sorry.

 I don't see anything wrong with telling people where they can get Rigol equipment from a reputable source.

[Simon]

perhaps website link may help so we can see who you are

[Simon]

The description of the DS1102E is somewhat misleading: http://www.mcs-testequipment.co.uk/product/rigol-ds1102e-100-mhz-digital-oscilloscope-with-logic-analyzer/ you basically state that the "E" model has a 16 chanel logic analyzer. The "D" model has the analyzer, ok I know there little brochure is available for download and you put "DS1000D" in brackets but I don't consider a supplier that is so ambiguos worth my time, just out of curiosity how much are you selling that scope for in the UK ?

This is strange because i have a problem with my scope and have been talking to Rigol about this, early last week i asked if they had a official distributor here in the uk, that i could send my scope to for repair instead of sending it to china. They said they have no official Rigol representative in the UK? If you are really the UK official distributor, then maybe you can also sort out my problem. The Scope is still under warranty. So where do i sent it too ?

Yes i did notice you say "All products purchased thru us are locally supported here in  the UK" but surly if you are indeed the official UK Rigol , you should have a close relationship with Rigol China and would be able to deal with all the scopes that are currently in the UK and offer full support for all Rigol products.

Hi Dimlow,


 I would be interested to know who you spoke to in Rigol  as we are Uk distributors for their products. 

 We are their distributor/sales partner for the UK, but we are not a UK repair center.  We do not get any money or reimbursement from Rigol for repairs.

As with most any type of test equipment you would purchase , you will need to return it to the supplier who you bought the equipment from. They should be happy help you and should honor the warranty they supplied you with.

    We only support Rigol equipment which is purchased thru us directly. 

 If you are having issues with your supplier, if you send me an email with what your issue is  I can ask some of the local repair houses that we use if they can repair your unit and send you their contact details directly.

Have a good day.
Joy

My exact thoughts to !

[Simon]

thats fairly reasonable considering most of us bought ours off ebay for £ 239, basically rigol offer no support and sending it back may mean never seeing it again

[Dynomo]

Dave you should ban spammers from posting products and prices on these forums.

I would give them some advertising space they rent, buy. Then everyone wins as it helps pay costs towards new blogs and running the site.

RCgroups does this, check it out !

Normally I would agree, but from my point of view Joy's posts are acceptable, as she is actually contributing to the discussion and trying to help out IMO.

Hi Guys! This is my first shot at this... Referencing the Rigol Scope. Is a 50 Ohm terminator on A or B inputs necessary ? Will improve display ?
Please advise...

Terminator is usually used only if your source and cable is also matched to 50 ohms. For normal 1:10 probes, the terminator should not be used.
