Not want OT but just sidenote: Have you looked up to date SDG2000X  Service Manual. ;)
Python, NI... etc.+

But overall, imho, we need some serious and wise discussing about calibration related things.
Least it need also look with manufacturer eyes (who is also responsible about product warraanty)Then it need look with distributtor/seller/service eeyes and then, importantly, also it need look with "end user" eyes. Also need look with: who is responsible in different cases if some unwanted things happend when doing adjustments.
These all are bit different cases and need bit different approach angle.

Is it also good that Siglent improve calibration/adjustment system so that it also keep nonvolatile log inside equipment and it can show  cal  counter/id visible in system status screen or something like this. In some places equipmeents need valid cal certificate. If cal is not secured how certificate can know it is valid and after then no one have done failed cal. How to secure it.

But I think it is better to start with dedicated thread for these manifold things around cal..

Maybe you should read the thread - the calibration procedure requires "EasyTest" software. This has so far been "unobtanium" - Even tautech, a Siglent distributor, has never set eyes on a copy. I don't know if rf-loop has it either. Why it isn't provided as a download alongside the ServiceManual document that references it I don't know? ... and yes I have asked Siglent in the past and just got no response.

Do I need it right now this second? No. But in a couple of years when Siglent will have dropped all support... Yes, I am pretty sure... Only nobody will have a copy of this elusive software when they finally need it.

Again you talk with a hole in your head.  :palm:

Please re-read the posts.

FYI, I have never had the need to ask for Easy Test nor would I (and most other distributors) have all the reference equipment required for specific models and series of Siglent gear. Each unit has specific required references as outlined in the factory Calibration certificates that I doubt other than Cal labs would own.
So, no way would I attempt to Calibrate any Siglent equipment, we have a good Cal lab not far from me whom with Siglent's authorization we would appoint to ensure equipment meets manufacturers specification.
Anything less is a half-arsed job IMHO.  :--

Macbeth is on another planet IMO.  ::)

I'm on another planet? Perhaps you would like to read the calibration and adjustment procedure from Siglents own manual and try and figure out what planet they are on?

--- Quote ---I asked burkm a few quite reasonable questions that he has not made any attempt to answer, maybe there's a language problem, I don't really know?  :-//
Siglent Tech support (and I am not) would ask exactly these questions in an effort to establish what problem, if any exists.

--- End quote ---
Why do you think there has to be a problem with the instrument? burkm quite reasonably wants to know how it is possible to calibrate and adjust his instrument exactly as Siglent not only state, but RECOMMEND in their own document...


--- Quote from: SIGLENT ---Calibration Interval

The instrument should be calibrated on a regular interval determined by the
measurement accuracy requirements of your application. A 1-year interval is
adequate for most applications. Accuracy specifications will remain valid only if
adjustment is made at regular calibration intervals. Accuracy specifications are
not valid beyond the 1-year calibration interval. SIGLENT does not recommend
extending calibration intervals beyond 2 years for any application.

Adjustment is Recommended

Specifications are valid only within the period from the last adjustment.
Whatever calibration interval you select, SIGLENT recommends that
re-adjustment should be always performed within the calibration interval. This
is necessary to ensure the accuracy of the performance data measured during
the calibration interval.

--- End quote ---

So Siglent clearly highly recommend not just a performance test but actual adjustment every year (or 2 years max).

They then go on to explain how to do this using the elusive "EasyTest" and even more mysterious "script prepared previously" (Where, when, by whom?)  :-DD

For the avoidance of doubt, I do not expect a distributor such as yourself to do this and it is clear burkm doesn't either. This is something an end user can do providing they are suitably competent and have the equipment to do it. If not then they can use their own organisations calibration facilities or farm it out to a third party provider.

I have previously asked Siglent for this "EasyTest" and got nowhere. I'm pretty sure no calibration facility has this proprietary stuff either.

Translate to your laguage words "script", "prepared" and "previously". (perhaps "previously" is confusing you but there it is just under your eyes if you read this manual.

What is this "got" and "nowhere"?

Overall after reading these comments I'm quite sure EasyTest software for these named equipments must never set for public distribution.
