Mine came with a calibration certificate in the box. Not good enough?
"ours" too, but it´s too less.
For example, what exactly was measured, what are the tolerances, which values were measured, where is the individual measure-protocol...
Example two, lets say, a value is specified with a tolerance of 1%.
Siglents "one sheet" says, everythings fine.
But did they really tested exactly this point ? And what are the value, is it inbetween the given tolerance or hard on the edge...
And so on.
Of course we can do measurements with the scope without calibration, but then we couldn´t use it for our factory acceptance tests
Our couple of "little" rigol and siglent scopes (DS1000Z and SDS1104X) aren´t calibrated, we use them for pre-tests only.
But our need of calibration is an advantage for all who wanted to know how good the sds2k+ in detail is - I´ll present the results here...
Maybe they need DAkkS Calibration ?
Not for everything, but everytime from a DAkkS accredited cal-lab.
The pics: SDS2104X+ and WS3024Z side by side - I coud swear, they got the same lcd screen..
Pic of the version, pic from the certificate.
BTW:
Maybe nothing new for others, but for me it was new:
The power-button of this new sds2k+ doesn´t lit/glow anymore when in standby, only when in operation.
