Good morning guys, I've recently have gotten an Hitachi oscilloscope 20Mhz model V-222 from a retired tech i havent gotten any probes with it. I want to by a pair of probes so i can do some poking around (im very good with a DMM), I went on ebay but i dont know what probe will work or what the differences are in terms of probes saying 100Mhz or 20Mhz, which probe is best suited for the instrument i have Hitachi oscilloscope V-222 20Mhz?
Good scopes the Hitachi's 🙂
Ideally you want a decent switchable divider probe offering 1:1 and 10:1 ratios (often incorrectly referred to as a 'times one and times ten probe). Also useful are simple shielded BNC to croc clip leads.
The 10:1 range on a probe should be adjusted individually to suit the channel on the scope you are using by adjusting the trimmer cap in the probe to give a correct squarewave when looking at the 'cal' signal on the scope front panel.
For a 20Mhz scope you really need 50 or 100Mhz probes.

Something like this is OK as a general purpose probe :

Ok, thanks for your suggestions (im living in the Caribbean) so the one you sent me in the link is a good way to start but its not available in my locale.
Is this one ok (actually im getting a pair)?

Well as i said Mooly, i just want something to get doing some tutorials and practice and that is easier for me to get. There are more better ones available as i supposed but as time progresses i may even get a newer more modern scope if i develop the skills to use it as (or near) like a pro.
The stated maximum voltage rating in 10X mode is 600Vpp, which is 300V max peak. That's too low for working with tube gear, but fine for almost everything else.
Thanks BinaryMike, but mostly i only do car audio stuff and flatscreen tv's, ive never been on a tubeset before except for CRT television which i gave up.
Hey guys I need a voltage compensating probe for ground isolation use. This one....

....doesn’t use a standard power supply but a USB power chord, is it safe to use the usb data port for powering the probe to do isolation checks from the scope itself?

Should be - its meant to be isolating after all. Wouldn't be much use if the power supply had to be via a mains-isolation transformer!!
A quick multimeter test can reassure you.
