Re: Switching a Tek TDS 5204 to 50 Ohms input impedance - Strange!
Hi Raymond , I have a couple of TDS's , a 744 original version and a 420A . Both are protected on the 50R input setting so I would expect all others to be the same . I have noticed this behaviour when using the 50R input and until I got used to it having wondered what was happening at first I much prefer it to the action taken by the 7A29 7k plug-in which just disconnects the input - and you need to disconnect to reset it.Regrettably I am just a hobbyist pensioner nowadays so my experience with anything newer than a TDS744 is zero , give me 500 series or 7K series even a 661 and I am happytoggle quoted messageShow quoted text

These were my thoughts exactly. I wanted to add that the 50 Ohm input may be protected but for a fast 'scope, the circuits would be tiny, so difficult to fully protect. Unfortunately, I couldn't find (the BW of) a TDS 5204 so decided not to write my reaction. Probably an MSO5204?

So, not an error at all, just clever design!
