DS1074Z - Decode RS232 ASCII problem

• DS1074Z - Decode RS232 ASCII problem
  Posted by matkar on 10 Oct, 2015 09:46
• I've found a problem with the decoder. When decoding character "8" it actually displays "9" when in ASC mode. Other modes (HEX, BIN, DEC) return the correct value.
  I've tested on 38400, 8N1.
  I have the original firmware it came with the scope: 00.02.01.SP1
  
  Is this a known issue? Has it been resolved in newer firmware updates?

  No problem here, running latest fw 00.04.03.SP1.

  Obviously it's time for an update...

• Have you tried all other characters and is it only '8' that's wrong?
  I'm thinking perhaps your actual baudrate doesn't match what the scope is set to so it misinterprets.
  I don't have a DS1054Z myself, just thinking out loud....

• This bug was fixed in version: 00.04.02.03.00.
  
  "4. RS232 decoder shows ‘9’ for ‘8’ input in ASCII format."
  
  (According to the firmware release notes).
