registry of DS1054Z scopes with and without 5 us jitter
« on: November 23, 2014, 12:08:28 PM »
  This is meant to start a bare-bones thread listing the serial numbers of Rigol oscilloscopes that have been found to suffer, or not to suffer, from the "5 us jitter" problem discussed at length in another thread.  After this header, every other post in this thread should say just
<serial number> has 5 us jitter
or
<serial number> doesn't have 5 us jitter

  Before posting, test your scope according to the following protocol:

  • Look at a reasonably stable multi-MHz signal.  For example, look at the crystal clock input of a convenient microcontroller.  Do not use one of the internally-generated signal sources of the scope itself.
  • Compare the apparent trace widths at no delay, 5 us delay, 10 us delay, 15 us delay, and 30 us delay.
  • If the source is unstable, you may see the apparent trace width monotonically increase with increasing delay.  Find another source and try again.
  • If the apparent trace width doesn't vary with the delay, then your scope doesn't suffer from 5 us jitter.   Post that.
  • If the apparent trace width is narrow at delays of 0, 10, and 30 us, but wider at delays of 5 us and 15 us, then your scope suffers from 5 us jitter. Post that.

Hopefully they are not upgraded ones, also you might want to keep your serial number to yourself because others can use them.

Meaning that I could enter your serial to create an unlocked scope that will now have your serial number, at least that's what I think it will do.

Serial numbers on a public domain is not a good idea guys, I think looking at serial number ranges may be better.
