Rigol gets pretty good reviews for a low priced digital scope. I'm still partial to the old analog scopes myself, I got an old Tek 475 I'd give you if you want to pick it up (weighs a ton).

Smile Check Ebay

I bought a Tektronix 485 for $125 that came with probes and just came out of the calibration shop! Yes its an old box but having a fast time base with good sync lets you look at really fast signals too. More than just a fuel sender which is probably 30Khz max. You can find newer units there too.

Have fun,

I got my shop O-scope from e-bay. 100Mhz "portable" benchtop Tektronix 2337 with probes for around 100 bucks.

Whatever you get, I would highly recommend a 2 channel device. I have learned that more times then not, you want to know what is happening in two different spots at the same time....such as... why won't this output work if the input is triggering X. Sometimes the input is ****.

Galin;
Love the Tektronix 515A, I have a 516! When it comes to construction, these things are the most awsome! This kind of fabrication with silver tip ceramic combs & point to point wiring is never going to be seen again.
I'm no expert, but playing with an 'O'scope is just plain fun. I've used a Flukemeter scope, so handy! I love the big old ones, but they stay at home on the bench. The hand held scope fits in a tool box. what it lacks in resolution and features, it makes up in handyness & gets into the hard to reach spots.
Now you've got me thinking to use one to measure that whine in the headset and place a filter capacitor.

I have a Hantek DSO and a 4-channel 400 MHz Tek for the lab.

The Hantek was about $400 and i've used it in flight to capture ignition pulses. I've also used it on my office desk for debugging microcontroller circuits. It has a built in dvm as well.

An old 15Mhz BK, in use last weekend. It arrived at a friend's junkyard as scrap about 1990.

Bob K suggested this on a thread a few weeks ago, I have two coming now so I can't report on it, but Bob was impressed.

I have one of these Owon scopes and they are _great_ (and cheap for their features - I have a SDS7102). Almost as nice as my Agilent scope at work: http://www.saelig.com/category/MFR00...FYqFfgoda3oAMA

Nice picture, Dan, didn't I see that on ebay today? I recognize the waveform.

You can download a program called Visual Analyzer that will act as an oscilloscope on a laptop. It uses the audio input for the scope input. Displays both frequency and time domain.
