Dave,
Seems you're right, I was offered the capacitors (see email below).
I'm inclined to write back and accept the Caps - I am in a position to fix this myself but the time taken will be annoying. The consumer protection regulations in the USA are pathetic. OTOH, this is clearly a faulty build and they should do better than this, if Ford missed parts off your vehicle which affected its performance, would you be happy with "we'll send you the parts to fit yourself but if you mess it up, you'll void your warranty"?
This is disappointing Siglent.

Hi Ted,
My name is Scott Rocco and I am an Applications Engineer at Siglent Technologies North America. Thank you for writing in. We are familiar with the probe compensation issue. All of the SDS1000X-E products are in specification. There is no specification for “probe compensation flatness” between ranges. When you change ranges, the physical circuit is altered and the design/part tolerances dictate the performance. The probe compensation can be adjusted to minimize the effect.
Your serial number SDS1EBAX1RXXXX has a very slight dip in the beginning portion of the flat top of low frequency square waves (similar to the probe compensation signal). We are willing to send you 2 capacitors with instructions to make the changes yourself.
If we send you the capacitors we are authorizing you to open the scope and solder 2 capacitors in place on the mainboard. This authorization puts the full responsibility for the update on you the customer. If you damage the mainboard while soldering or something else happens electrostatically while you are doing the update due to misuse the warranty will be voided. Our warranty at Siglent Technologies America is 3 years on parts and labor unless product is damaged due to misuse.
If you have any other questions you can let me know.
Regards,
Scott
