Handheld Oscilloscopes

[NB50 206]

Well Ive wanted an oscope for a while now and crt scopes are a little out of the price range even used ones.

Im wondering if the hand held ones with the lcd screens would have enough resolution to see a clipping sine wave. Ive seen the video how the were showing how bass boost is bad but cant really tell how good the resolution of the lcd screen due to video quality.

Ive used crt scopes in electronic classes and wondering how lcd compares to crt

So who here has used the lcd scopes and are they sufficient enough for car audio. I used crt scopes in electronic classes

Heres what im looking at

I just bought the special edition version of that o'scope and I definitely recommend it. Here's a pic of the resolution of the sine wave just before clipping. You can definitely see clipping and because it has the 'auto' function, it'll get the screen and time division just right to clearly represent what you're monitoring.

that's the version that I got

That was quick thanks

What was the difference between the se and regular is it just the back light.

thats a good price on it also wish I did eBay but I stay away from it and there is a couple other things I want at parts express.

I think the main difference is the SE has a cool little carrying case, the regular doesn't.

actually the one I got has a lot more functionality

find an up close of both and you'll see the difference in buttons. The HPS10SE is comparable to the HPS40 cause they share an instruction manual. It's definitely worth the small price difference to get the SE.

Psst, the 10 and the 40 both share a manual.

I've got one in my lap here, the 10SE and the 10 are basically the same thing.

SE has .1mv sensitivity and 10mhz sampling rate

HPS5 has .5mv and 5mhz

Also the SE has the x10probe, you have to get that extra through parts express...

I'm just saying if the HPS10SE is cheaper and better, why wouldn't you get it? (I paid $167.53 shipped)

Same as the HPS10, but with blue LCD, white backlight. Comes in a rigid carry case.

^ hes faster then me. Yeah went and did some research they are the same except for the back light which would be nice but would also drain the battey faster. It is cheaper on ebay but I dont buy any thing from ebay even if it if a little cheaper just something Ive got against ebay and fear getting screwed.

I stand corrected.

[NB50 206]

if I can find the link to the one I bought, you can totally trust the seller. I just bought one and you don't have to worry, plus the price is great. I think the seller has like 8000+ replies and is a power seller, basically like buying from a business online.

Well for some reason they raised the price and that's why I couldn't find the listing. It's now $199, I paid $155

sorry about making you think it was cheaper...

They also have the regular version for $175 shipped

IIRC, the main diffrence between the hps10 and hps10se is the backlight and the carry case.

[topgun 262]

It doesn't matter which one he gets, any of them will be accurate enough for what hes doing. Whatever error they have will be good enough for audio and setting gains, its not like hes doing digital circuity work.
