Best oscilloscope for amplifier repair

I need to be able to check the performance of amp and see if my input signal is distorting, deteriorating, has interference or other types of problems that plague audio. What the max MHZ range would I need to aim for? What other features would it need or be handy? Do you know a specific brand and model? Do you think I need any other equipment?

The Rigol Z. It's a 50 Mhz DSO. It has 4 channels and a host of features I'll only use half of. Frankly, it has more functions than I do.

I downloaded a free code that unlocked a wide array of expanded triggering options and made it a mHz scope. I went from Fred Flintstone to George Jetson. You do not have the required permissions to view the files attached to this post. I was very close to pulling the trigger on the exact scope and unlock the features as you mentioned. Unfortunately, the taxman cometh with a heavy hand and I had to pay heavily.

Oh, well - guess I'll struggle with my analog scopes a little longer How long did you have to wait for the scope? Seems like the longshoreman strike really messed up the deliveries. I can't complain though, considering the price , and the fact that I had the old analog scope still.

I'll bet these will be available for some tme. When you can pull the trigger they might even be cheaper! That is to say, what can you do with one of these very nice indeed Digital Scopes that cannot be done with an Analog Scope.?

Thank You. DSO's have a bit of a learning curve, but they're pretty darn handy. You get a lot of features for not much more money than an analog oscilloscope. They can be really convenient, with the suite of automatic measurements, voltage frequency, duty cycle etc.

Plus the cursors, 4 channels, etc. Re: oscilloscope Post by Structo » Fri Apr 17, pm The display is so much better on those new scopes. Oh and since no CRT, they aren't three feet long!

You can probably connect it to a PC as well. I looked up Rigol and they have a branch office just north of here in Beaverton. Amazon also carries some.

Re: oscilloscope Post by johnnyreece » Fri Apr 17, pm You guys are giving me oscilloscope fever My wife will not be tickled at the prescription.

Don't know the input voltage rating though. Today, about the only advantage analog scopes have is simplicity, twist 2 knobs and you're up and going. I think I paid for my BK scope about years ago. And yeah You know how people are with used equipment, everything, not just scopes and guitar amps. I see those old Techtronix scopes on Ebay and Craigslist for bux. Those are what I guess people think, because they were grand when new I had been looking at one of these Not sure about the quality of the Chinese built test gear but the prices are sure attractive.

An o-scope is an electronic test tool that enables the consumer to observe variable signal voltages on a monitor. It may also be used, based on its characteristics, to show other forms of signals that are translated to voltages, such as vibration or tone.

I also recommend Rigol DSZ or even better DSA. They have probably the best permomance/price ratio.

Are You Using The Best Oscilloscope For That Application?

David, aka Grumpy, needs our help. Great news. David is home! It was quite the ordeal to get him home and into the house, but it is done.

Specializing in tube and vintage amps and effects, expert technician Pat McKeever brings a toolbox filled with more than 25 years of experience repairing, maintaining, and customizing amplifiers. Unlike most guitar repairs, amps require testing and close inspection to get an accurate diagnosis and cost estimate. That said, some ballpark costs for common repairs are listed below as a general guide. Recommended as annual maintenance. Keep your rig in tip top shape with this basic service.

Oscilloscopes are used in diverse industries from sciences , telecommunications, and medicine to automotive and engineering. While there are many types and models of an oscilloscope, these can be divided into two major classifications.

Oscilloscopes are used in electronic testing to observe varying voltages in a signal and then plots those voltages against time through graphical representation. This allows signal voltages to be viewed, usually as a two-dimensional graph of one or more electrical potential differences vertical axis , plotted as a function of time or of some other voltage horizontal axis. Oscilloscopes even can perform analysis over non-electrical signals by converting sound or vibration into voltages, as in medical and automotive industry applications. Further, they allow for observation of constantly fluctuating signal voltages. This is done by displaying the waveforms formed due to changes in electric signal over a calibrated scale. The waveform can then be analyzed for properties like frequency, rise time, interval, and amplitude. But the quality that makes oscilloscopes invaluable in any electronic laboratory is their range of utility.
