Tektronix TDS 520D Channel hack

• Tektronix TDS 520D Channel hack

• Hi!
  I’ve got a Tektronix TDS 520D oscilloscope, which is kinda old digital oscilloscope and has kinda weird channel configuration.
  It has 2 regular channels and 2 “auxiliary” channels. It can display only 2 channels any given time.
  
  This scope looks very similar to TDS540D which has 4 regular channels and it can use all of them in the same time.
  
  Do you think that the TDS 520 can be hacked to think it is a TDS 540 and use all the channels?
  Does anyone have experience with that?
  
  Thanks,
  Mate

• The TDS520 and TDS540 scopes have different acquisition boards, so it is unfortunately not possible to have all four channels active simultaneously on a TDS520.
