Looking to buy an oscilloscope

[skogie1 10+ year member]

Any recommendations? Something very cost effective? Looking at this one.

FLUKE 99B SCOPEMETER Series II 100MHz | eBay

I'm a little confused though, it says that the bandwidth is 100MHz to 349MHz, far beyond the 50Hz and 1KHz I'll be using for setting the gain. Is there something that I don't understand here or is this scope simply not going to work for me?

Thanks.

That is a lot of cash if you just want it to set gains. Set your gains by ear and spent the cash on something that will do more for your system.

Not so much...

I use a tpi scope plus 440, and it is worth its weight in gold.

Agreed, setting gains by ear is inaccurate at best, and reuquires specific test CD's and a trained ear. Scopes are the way to go.

That scope is for higher frequencies, like many handheld scopes.

Get an older BKPrecision or Tektronics or Aligent or even TENMA bench model, not handheld.

Anyone ever use an iPhone app to set the gain? I see that there are a number of o-scope apps available. Don't know if any would serve this purpose or not. Anyone??

I use this to set all my gains and it works great.

In the specs it sais "freq 1hz to 5 mhz"

Reading FTMFW

Thanks for the suggestions. If I have an o-scope iPhone program and play a frequency tone and simply let the program "listen" it will show a sine wave. Will that work to set the gain? If I turn up the gain will that sine wave eventually clip, just like it would if I had connected terminals to the speaker posts? Curious...

your iphone wont pick up bass, or at least not accurately. in fact its probably worse to try and set it with an iphone than it is just using a dmm
