Some times sales persons have never seen product irl what they sell. How can ask these sellers offer some repair service or technical after sales customer help. Just, nothing.
But the product is cheap. What do you want? If you want decent service then you have to spend more money.
Tautech deserves a big pad on the shoulder  :-+ for trying to clean up after Siglent but even he has to realise this whole affair just eats into his profits (time spend and sales lost).

What I want. Question is not what I want. Question is what customers want. Question is what kind of service I can give to customers from my own pocket. I have not made these mistakes, but I am responsible in live practice. Not perhaps legally responsible but I have my reputation and I have faces and both of these are values-property what I want not easy loose when others make mistakes. This is what push me, and example even more Tautch to work things what do not belong to me or he. Perhaps I can go to Siglent factory and tell that this lot you do so that I control and watch it from components to ready product and all do under my eyes and control. Then I can be also responsible but then I also want my salary.

This is why I ask previously and kindly: It can also ask from Siglent if it is intelligent or stupid to break the camel's back if there is still long way home.

I drive a LEC (low el. consumption) BEV car. Smoke exhaust pipes - go to museum. In Finland quite all electric power is made using nuclear, wind, solar and water.

THIS ^^^^

Despite other offers of distributorship from competing brands I choose to remain a Siglent only distributor and the benefits are that the information can flow freely to you all. Yes I could represent other brands but the problems others have with worse support and poor design can only lower what reputation I have in the industry  and worked hard for. Like rf-loop but with much less experience, I look hard at the equipment, what it can offer and sell and support accordingly. Siglent models that have not progressed, are outdated or are priced at the very bottom of the barrel I WILL NOT STOCK !


I say here and now to Siglent that I will re-attempt to arrange a video of SDS1202X-E rework as it was abandoned after some pressure on me from high in Siglent. Only now after it has been very clear that management won't assign resources to do rework for customers at service centers it is now important that good guidance to do the rework is available online.
It is not simple easy but capable hobbyists with some care and SMD experience and a sig gen capable of 10 KHz square wave @ 1.2V and 12V can do the rework. It is not hard.
At least Siglent have given us a detailed procedure that matches production adjustments.

This problem will shadow Siglent for some time to come and it is a shame that SDS1202X-E has been tarred with this brush, it is a very good little DSO and soon will be my best seller.

Seriously, You should take the other distributorship offers.  Siglent will ditch you at their earliest convenience (i.e. If they find a way to sell directly, cutting the middle tier).

If the producer of the video linked below is to be believed then this video is confirmation that Siglent or one of its distributors are knowingly and actively distributing problematic oscilloscopes. The fellow in the video states that he purchased this particular scope at a reduced price from Siglent after they declared that it had a known repairable problem.

He states that he wrote several companies looking for second hand units, demos, etc. and Siglent replied that they had this one which was a former lab unit.  The way he describes it, they did not inform him of the issue, and apparently did not add the capacitors before sending it out to him from, presumably, the factory.   :palm:

Quote
For fellow member StillTrying's sake and sanity it is about time and good to hear that Siglent are finally going to address the outstanding firmware issues with the still current CML+ series. I seriously ask, does Siglent have a disgruntled employee or saboteur in its midst ?, no company I ever knew fucked things up so badly or on such a regular basis, I feel sorry for their good agents and distributors who once again have to tolerate this crap.

Outside of this forum, just what percentage of USA buyers have recognized an issue with any of the products and are contacting their dealer/distributor/the factory for repair/replacement?  My guess is that the percentage is quite small.  I suspect that Siglent USA has made a calculated cost/benefiit decision to arrive at their current position.

Let's face it, a lab is not going to be considering Siglent for their test equipment line up.  If I were outfitting a lab to set up a repair business I would be looking at Tektronix and comparable OEMs.  Siglent is clearly aiming at the hobbyist/student/part time repair shop market where Tektronix reputation is not the first consideration in the purchase.  In this forum this issue is getting quite a bit of attention but outside of forum members posting reviews on Amazon, this issue is unknown.  I know because even in my searches a few weeks ago this thread did not come up.  Five star reviews are still being posted on Amazon indicating satisfaction.  I would have posted a five star review up until February 11.  So let's not think this issue will actually harm Siglent in any appreciable way.

Fact is that I had not heard of Siglent in amateur radio circles, which is somewhat surprising or maybe I just wasn't paying attention, and only discovered them via an Amazon search for DSOs.  I watched several of Dave's videos regarding Siglent products and my impression was that for the money it is a good product especially for its targeted market segment.  I'm going to continue to work toward getting a BB 'scope no matter how long it takes as I really like the feature set and small footprint for the occasional work on amateur radio transceivers I want to do.

As Amazon is the most visible venue for reviews of the product, in the USA at least, so long as the review percentage remains high, Siglent USA will continue to let the BA stock move out the door as the few returns and complaints will cost them little.  It stinks to be sure, but is the way of the modern business model in the USA.

Note, this is not to defend Siglent USA but to explain what I see going on knowing the corporate world as I do.  If I get a BB unit, I will likely adjust my review to four or five stars.

After another appeal to Steve Barfield, he offered to allow me to RMA my scope for a refund (less shipping) which is OK but he's never apologized for falsely accusing me of leaving a 1-star review and he still insists that the compensation issue is not something covered by warranty.

Siglent America could and should have done the right thing from the start, fix all these scopes under warranty.

I could go buy a new SDS1202X-E but I deiced to buy a DS1054Z instead.

Unless it was 1st tier equipment, not much interested. Some offers are interesting but when you look harder at their product ranges.....yeah, nah !  :=\

Been through that exercise years ago when I was looking for scope brands to sell and all the 'good' stuff is spoken for by long established dealers in this part of the world.

It is precisely because AMZN is so visible that details about the product and the support (or lack of support) behind the product from the manufacturer be included in reviews there. 

I do hope that, if/when you get a BB unit, you detail what was wrong with the first one and the steps you had to take to get a corrected one.....

I just saw it and the 2 and 4 star negative comments, and noted that even the 5 star comments were not unambiguously positive.

Amazon.ca shipped me a second defective unit ("BA" serial) I confirmed the probe compensation defect.

I'm packing this one up and returning it too.

Amazon.ca is offering 3 options;

1: Return both scopes fur a full refund.
2: 20% discount on the original shipped unit
3: Try a third time

I'm going to try a third time. I'm making it clear that if it is also a "BA" serial number that I will be returning it too.

I think we should have a poll on whether you get a third "BA", I think the chances are high. :horse:
.  That took much longer than I thought it would.

I just received my replacement from Amazon earlier this evening and am happy to report that it is a 'BB' unit and now there is a label on the outside of the box with the model and serial number (maybe it was covered by another label on the previous unit?).  I've had it on just a few minutes and I've played with it just a bit using the compensation test point and the square wave is much more stable while cycling through several ranges.

Purchased through MegaDepot, about a week ago, must be a dropshipper? Still no word on shipping, could be a good thing if I get a bb s# if not it will go back, truly a shame  how this has been swept under the rug. Such a great scope otherwise.

My sentiments entirely.  I liked the scope but the attitude towards me as a paying customer...

All things being equal, people will do business with people that they like.

The serial number was not on the outside of the box. So I opened it to check -- another "BA" serial number, and I confirmed the compensation issue -- they are not sending out fixed units - they are trying to unload the defective ones on unsuspecting customers. Amazon assured me that they had checked and that a correct unit would be shipped. It was not. Again, I don't blame Amazon -- I believe Siglent is to blame here.

Hello,

It is true that Siglent would have had to take over and replace the known BA stocks at the resellers, it was the easiest and least expensive solution.
Similarly warn distributors of the problem and see with them if they could install themselves 4pf capacitors.

Can I ask if it was double boxed or single ?

If double boxed, the SN# is never visible, only on the inner box on one end.

Single boxed. None of the three units I have been shipped have the serial number on the outside of the box. They have all been "BA" serial numbers, and they all have the probe compensation defect.

Amazon.ca is not giving that option -- it's now just "return for full refund"
And I updated my review to 1 star.
