Look man, I have wanted an O scope for YEARS!! And one for $50 DOLLARS?

REview from a person who’s english is his second language… SO YOU KNOW HE’s SMART!

NOW.. Who wants to show me how to use it without breaking it!

Reason why I got it was I have always wanted to measure DC power ripple in my Car Audio Power system, and also, check out the output of inverters, and also, I am building some Class A amplifiers etc.

I was thinking about getting the PC based one, but this with the buttons right there will make this easy to learn with.

Have not touched a scope in 20 years… last time was to measure output of a disk drive while aligning it. Looks cool, but no comparison to the 100lb ones we used to lug around.

No longer can we walk away, we must run. Remove the motive power.

Wow — looks like a great deal (though I’d dig into the specs very carefully to make sure that it’ll actually be usable at the bandwidth they claim). I’ve been chugging along with a 10 MHz dual-trace Heathkit ‘scope that I got secondhand back in my high school days (impressed the hell out of the physics teacher when I brought in Polaroid screenshots for an extra-credit project I’d been working on — he gave me 15 points out of a “maximum” of 12 on that project).

I think the last we had at the shop was a TekTronics? Man, been forever ago. Like 32 years

I’m just glad that I am going to be able to at least to some real tests and see what I am hearing instead of just giving some subjective tests.

I’m really going to have to get a book or really take a class and get into how to use one of these things properly in order to take advantage of this one. I doubt I am ever going to outgrow the thing since most of my measurements are going to be below 20 Khz and mostly in the audible spectrum.

I know unlike my multimeter, I might have to use some custom circuits in order to test High voltage/high power sources like AC coming from the wall or the ripple in Automotive DC electrical systems.

I just got a DD-1 from Steve Meade and I have Yet to open it. But I have got my light meter. WHOA! Used the HELL out of that thing. Amazing what a meter can tell you.

Tektronix is right down the street , and I have been wanting to take a tour of the facility for a while now. One day.. One day. Amazing how many High tech companies are Right here in my own backyard.

Not to mention MY FAVORITE COMPANY OF ALL TIME! AudioControl! 🙂

Any tips, I would love them. Thanks Gents!

They keep getting cheaper and cheaper.

A DC battery should have no ripple at all. If you are having ripple on a DC line that can smoothed by increasing the bus capacitance. You need to identify the source of the ripple and filter it as close as you can at the source.

Couple of things to keep in mind when first using an o-scope. The probes that you use will typically have a switch 1x, or 10x and sometimes 100x on the probe. This reduces the measured voltage on the tip so you probe higher voltages. Just keep in mind you need to set the channel appropriately on the O-Scope or your readings will be off by an order of magnitude. There will also be a bias capacitor on the probe that you may need to calibrate from time to time with a small screw driver.

The Alligator lead on the probe is almost always earth grounded. This can cause short circuits so be careful how you use it. Best way to measure with high voltage situations is to use two probes and take the difference between them to see the waveform.

PM, if you have questions I may be able to help you with this problem.
