Hi all,

I've currently got 13 scopes of various types; most of 'em vintage. I
like it that way, old stuff. But it's far too many scopes in all honesty,
all taking up valuable space. One of the candidates for selling-off is a
4 channel Philips job (plain analogue). I can't remember ever having had
a need for examining 4 signals at once, but thought I'd better check with
the Panel first, just in case its a rare and valuable beast and nothing
else will do for some obscure application that may well crop up as soon
as I no longer have it around.
So... get rid or hang on?


Channels 3 and 4 are good for when you've blown up 1 and 2.

(I have a 3-channel HP scope that I bought off eBay.)

Lots of times multiple channels are useful in looking at logic or serial
buses such as SPI (clock, data, chip select, DAC output).
