Atten AD7042CA digital oscilloscope purchase

[alan monro]

Good day ,
My old 30 meg BW cro just died , all of the power supply electrolytic s need replacing.
So I  purchased a new 40 meg digital oscilloscope .Atten AD7042CA. and it is being delivered in a couple of days .
It is brand new and $200 . I think  the AD7000 series came out in about 2008 .
There is not much info anywhere about them as I tend to think they were badged with many other names .(maybe Techtronics ?)
Would any one have any knowledge `about the cro as it would be greatly appreciated.           Thanks Alan .

Umm, why would you want to buy a 40meg CRO for 200$?

Good day T4P.
I accidentally referred to my new purchase as a cro . silly me!...................Alan

Howdy, i can not find any info what so ever about that model..are u sure its 100% same one , and where did u mange to purchase this?

interested getting a cro (digital/analog) $200 sound quite reasonable for a beginner..

Closest model I can find is the ADS1042CA (which is indeed 40 MHz). I just hope for your sake it's got fairly recent firmware loaded on it, else you may in in for some hassle.

I purchased it from Triosmartcal in Australia . Slightly different case , same firmware as ADS1042CA thats all . A bargain at $199 +$12. delivery

Yes this would suit a learner with its switchable foolproof automatic functions They have sold a lot of these to TV, electronics servicemen and have had a lot of praise from the same ,
.I am a retired technician and have the ability to spot an absolute bargain so thats why a purchased it.......Alan

[Bored@Work]

Excuse me, you sound more like a car salesman, than a retired technician bargain spotter. What you have "spotted", i.e. you want to sell us, is what we in the industry call a lemon. Especially since there aren't many TV servicemen anymore, so Atten couldn't have sold a lot of these DSOs to them.

And the autoset function doesn't suit learners, it prevents them from understanding what they are doing.

[alan monro]

I respect your view no matter how wrong you are. How about doing likewise .
Can we keep this a friendly forum .??

No, that's just Bored@Work being his usual cantankerous self.
You are welcome, and you'll find this by far the best forum to talk about scopes and other test gear.

Hi Alan,

It looks on Trio Smartcal's website like it is a cathode ray oscilloscope (albeit colour) rather than an LCD one.  Is that the case?
I guess it should do the job well if you only need to look at low frequeny signals and don't mind it taking up a bit of bench space. I like the button and knob layout on it. How easy have you found it to use?

It also only has 250 MSa/s per channel which isn't huge. Did you consider spending an extra hundred dollars or so and getting yourself one of the 60-100MHz 1GSa/s models available on the market?

No, it's LCD.
It's an old model that TrioSmartCal would be clearing out. I saw these type on my last trip there, and one (Atten) was in my video

You are right Dave I think the 7000 lcd series came out 2008 . There was a review in silicon chip Febuary 2008 of the 60 meg version ie AD7062CA and they absolutely loved  it . The specs are the same except for the response.
I dont mind a new older model as long as it is fantastic and i can afford it.
The only real difference between mine and a new model is the new ones are much dearer..................Thanks Dave........................Alan

[T4P]

Are these one of the earlier models that Atten got into a lawsuit with Rigol? (Copying...)

[htassell]

My mistake on the display - I saw CRO on the description at the top and assumed they were being literal - but missed the specs of the LCD a bit further down.

Seems good value for $200 when you consider some of the DSO Nano's get above that price.

For sure, bargain if that's all you've got to spend, and don't mind the larger form factor.
No contest against a DSONano, which is only useful if you absolutely must have a pocket form factor.
$200 for a 40MHz dual channel colour bench scope with TFT was unheard of only a few years ago, even from China. But here it is in Oz. Granted, it's a clearance special. I recon you could probably resell it on ebay for more!

[alan monro]

I wouldnt be at all surprised . Most scopes are more or less coppied .............Alan

David have you ever reviewed an Atten . I am extremely interested in the build quality .etc . If you have would you please let me know  . Thanks...Alan

[T4P]

"Most?" Nah. If somebody did they would be in courts now. Unless it was Atten copying something from (eg)Tek in which case under the chinese law is allowed and if the overseas company tries to file a lawsuit, they will automatically lose in china

 David ,I forgot to tell you they have the AD7062CA( as reviewed in silicon chip Feb 2008  )the 60 meg version there for$230 . I didnt need 60Meg  thats why I got the 40Meg as I am doing mostly audio and computer projects once I can understand "C".......................Alan

Seems like this scope is in this family from Atten:

It looks more like the early Instek designs.  Key is this family of scopes do ~ 250MS/s per channel.

Thanks for the information but I could not use it . Somehow unknown by you there is malware attached to that site according to my antivirus . Thanks ............................Alan
