Hi guys someone owed me some money but didnt have it so they offered me a TRIO OSCILLOSCOPE CS1022 20 mhz dual trace if it works ok i hope i can use it on some lcd repairs etc and its more really to get experience of using a scope etc im just waiting for it too be delivered will update when it comes.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: Trio oscilloscope cs1022
cheers stj there the ones i ordered luckily the other day just looking for a service manual now i know this is a old scope but its mainly for me too learn the basics on really i know it will take time and a lot of reading up on stuff etc but hey we all have too start somewhere i guess.

Re: Trio oscilloscope cs1022
Yeah I think Trio = Kenwood

I wonder why some fairly famous audio manufacturers keep their test equipment under a different brand, like Viz = RCA, though perhaps Viz never made a scope, though they made fairly famous Voltohmysts.

Re: Trio oscilloscope cs1022
Guys have any of you got time to give me a crash course in seeing if this scope works correctly, i dont want too spend time on it if its faulty if someone is willing to help me set it up just so i can see if it works ok etc i can upload pictures/videos etc if needed, i am reading the user manual and watching videos etc on scope usage how to understand the readings etc, i just dont want too waste time if this scope isnt working for anyreason.

cheers stj im just reading the manual again too so i know what switches etc goes where and just found this video that looks quite good too and explaines using a scope thats easy too understand for a begineer like me.

Re: Trio oscilloscope cs1022
oh - a beginer.
go to sites like tektronix - they have stuff to teach new owners.

Re: Trio oscilloscope cs1022
I think most scopes should start showing a trace when freshly turned on. *most* ...
Digital scopes or ones with computer controls may not, but most should. Since the CS1022 is not a computer controlled scope, it's a bit easier.
Most scopes should be able to pick up stray currents induced by the main power line oscillation, so you should pick up a 50Hz oscillation in your locale (UK?). Start with "AC coupling" on one of the channels and rotate the position knob so that the trace is centered. Choose something like 500 millivolts/division. Then also set you sweep time to something like 5-10 milliseconds per division (BTW, a division is the distance between the graticule lines on your screen): At 50Hz a sine wave will complete a cycle in 20 milliseconds so you should see a several full sine waves on the screen.
Set your trigger to "auto", "internal", "DC(or auto) coupling" - this should be most common usage. Set your trigger level to about center.
Then touch your probe on some large conductive item not connected to line power. You could touch the probe tip with your finger.
You should see some nasty sine wave on the screen. You may need to touch focus or intensity to get a clean bright sine wave.
Hope this is sufficient to test things.

DSOs are computerized scopes.
There's also some old analog storage oscilloscopes but I've never actually used one. I'm curious how they actually work.
