Do mask test with DS1000Z and run signal what give result = fail. How many pass/fail test it can do in one second? For what it can use?

Usually not a valid point for hobbyists. Personally, I should never buy a 2-channel DSO.
Quite right, but with the pass/fail specs of this DSO it will be quite attractive for production checks and those that might need this won't want 4 channels.

I'm going to be a little harsh here, but this is my gut reaction.  Prove me wrong if you can.

How crazy would you be to put this instrument in a production test environment?  If you are ISO, you have to have every piece of equipment calibrated on schedule and they need to be repeatable.  Is that even possible with Siglent stuff?  How long would it realistically last (and stay in cal) running all day every day in a production test setup?  You may save some money up front, but will you pay for it later?

So I have to ask
How do you calibrate that scope?

Sorry I don't have Cal info on procedures.

"So I have to ask

Calibration is performed "closed-case" with a Fluke calibrator through the USB port.

I see you are in the USA. Transcat performs calibration on Siglent products at their labs throughout North America.

The last thing you want to do to a production test setup is worry about if it's accurate and have to fiddle with it all the time.  I understand we aren't talking about this class of instrument,  but relating to a production test environment and calibration and MTBF this is the blurb from the Keysight 3000T datasheet:
http://literature.cdn.keysight.com/litweb/pdf/5992-0140EN.pdf?id=2545408

Total cost of ownership:
The 3000T X-Series offers an extremely low cost of ownership. Between the standard
3yr warranty, an industry leading mean time between failure (MTBF) of over 250,000
hours and a market-leading calibration period of 3 years, you can rest assured that your
investment in a 3000T X-Series will be protected for years to come.

I figured it was closed case, I was wondering if you have to plug a USB memory stick with the proper program to put it into calibration mode or if it was a front panel button combination on power up.

Dave was loaned both the SDS1202X and SDG2000X by Aussie multi brand distributor Triotest not Siglent.
Triotest had to buy these from Siglent like all distributors.

BTW Dave mentions in the SDG2000X overview vid he will be visited by the Siglent CEO in December:

Very dicy to use Dave as a promo tool, he will tell you both good and bad points in your product. Sharp knife there, and a double edged one at that. if good enough you get something good in review, but he will slate you for any foibles and poor choices in his opinion you have made.

I will note also here that after previous 1.1.1.39.6 (this is not downloadable) and more previous 1.1.1.39.5 (downloadable)  Siglent have released new FW for SDS1000X series.
Current Version: 1.1.2.1R1 | Published?2015-12-18  (on the scope screen 1.1.2.1.1)


One major improvement: Old version Sequence mode can capture  up to 1000 segments as also stated in data sheet and Siglent side introductions about SDS1000X.  Maximum number of segments are now 80000.
It rise this function useability to totally new level. Speed is untouched and it can reach up to  500000 captured waveforms/s (aka segments) speed in Sequence mode when single segment lenght is 700 sample points and samplerate is 1GSa/s.  (New updated table is published there is SDS1000X thread.)
If practice and theory is not equal it tells that used application of theory  is wrong or the theory itself is wrong.
It is much easier to think an apple fall to the ground than to think that the earth and the apple will begin to move toward each other and collide.

Tequipment has this scope for $560, which is not too bad of a price point considering its features. Makes deciding between a hacked DS1054Z and this one even more difficult.
