I have two pretty good bench supplies, so, I do have that covered.
What I am really after is a new scope to sort of replace my old Tek scope. It has 100 MHz bandwidth and four channels.
I am spoiled at work with the newer digital scopes and would like those features. From examining the specs, my take on the product offering highest analog bandwidth is 55 MHz. This is probably more than adequate for what I do. Attached are couple of scope shots. (This model scope was Tek's last glass CRT model they produced.) One shows a SPI bus transaction and as you can see, this is a stretch for this instrument. I would be curious to know how the Discovery 3 would do on these wavefomrs.
