FNIRSI-1014D Digital Scope/Function Generator

Hey Everyone,

I just bought one of these online from Banggood.com.au, it is a combined Digital Oscilloscope and Function Generator which I think is just perfect for anyone interested in getting into amp building because it includes two very handy pieces of test equipment for doing tests and general debugging work on a guitar amp you're in the process of building, of course you can get by with just a good multimeter, deductive reasoning, and a liberal application of Occam's Razor (to eliminate possible causes of faults by reducing the number of unnecessary assumptions), but, at some point you need some way of checking how the circuits in a guitar amp are actually functioning, anyway, I thought I would start this thread so I could post a link in case other forum members were interested in buying one for themselves, so here you go.

Looks good. A lot more storage friendly than an old style oscilloscope!

Agreed, the screenshot capture feature is going to be very handy to have, I'm planning on using it when I do some tests on my Sloclone 50 build project.

This is really cool, and a pretty great price. The only bad thing I can see about it is that it lowers my resistance to think about building an amp. Now I just have the mantra to keep repeating to myself: "Dyslexics should not work on circuits that can kill them."

I could have bought a new Digital Scope from Jaycar, but they want something like Au$800.00 for one.

Update:

Well, my new FNIRSI-1014D 100MHz Digital Oscilloscope/Function Generator finally arrived in the post about a week or so ago, and I've been in the process of familiarizing myself with it, I've noticed that there are a few differences between my old DSE Q1804 20MHz Analog Dual Trace Oscilloscope, and my new Digital Scope, for a start, you don't need to do any mental arithmetic gymnastics when interpreting what you see on the display screen, it includes readouts like frequency, and amplitude, the display is rock-solid steady, bright and crisp, and best of all, I can take up to 1000 screenshots of what I see on the display which will be very handy.

Here's a pic of my new Digital scope, I set it up to display a 1kHz Sinewave signal coming from it's built-in Function Generator, you can select up to 14 different output waveforms, at a wide range of frequencies which you can easily manually set, I'm actually finding my new Digital scope pretty easy to use, you definitely do not need a degree in rocket science to operate it.

This new Digital Scope has five times the bandwidth of my Analog Scope, both are perfectly fine for DIY guitar amp building and servicing, but the new Digital Scope is less bulky and weighs less, so it is much easier to carry around, so far I'm really happy with it.

For those of you looking for an easily affordable Oscilloscope, you can buy these online from Banggood.com.au, this one cost me about Au$290.00 all up, including postage, that's less than what you would normally pay for a similar Analog or Digital Scope, best of all, it also includes a built-in Function Generator you can use as a signal generator.

It uses a 5V DC/2A usb phone charger plugpack as it's power supply, it comes with two Scope Probes, a lead for the built-in Function Generator, a usb power lead, a usb lead to connect it to a computer, and instructions.
