Noone is saying fans of analog oscilloscopes can't or shouldn't own them. But it's polite they wear a mark so potential beginners can identify their bias.
Most of the bias is on the part of the DSO proponents.
Mention getting a "cheap analog Oscilloscope",& they come out flailing:-
"Analog 'scopes are useless!"
"Secondhand analogs will always break down & are full of unobtainable parts!"
"They are too expensive for OLD analog,out of date technology!"
"But they're OLD!"
"I only look at digital stuff,so they are useless!"
"You mean I have to count squares?"
"They're so big!"
"What! no Auto button?"
" Did I mention that they're OLD!!"
"Who cares if my DSO reduces its sampling rate at long time/cm settings--nobody ever uses those settings!"
I could go on all day----"torn from the pages of EEVblog forums."
The facts are:
You
can buy cheap secondhand analog Oscilloscopes --even on eBay.
(ignore the silly overpriced stuff)
If you can,look beyond eBay--'scopes are often available at Hamfests for $100-$150 for the popular Tektronix &
HP models,& very much less for less well known brands.
At Hamfests,people arrive with a certain amount of money in their pockets,& are more likely to spend larger amounts on a Transceiver,so Test Equipment tends to not be their priority.
"Just get a Rigol DS1054Z!"---hah!
US $375
is not "chicken feed" for many of us-------let alone $A600!!
Even a secondhand DS1052E on eBay.com.au went for $A362---for an outdated model.
Another one is $A500!
Modern DSOs can do just about everything an analog Oscilloscope can do,& more,but this level of performance has been a long time arriving.
Why else are there so many surviving analogs--why didn't they all disappear like the Dinosaurs as soon as the early DSOs appeared?
