Hello, I am a beginner small circuit and high-frequency projects for amplifier equipment and driver circuits, and I am in need of a used or broken oscilloscope. I have broken several devices with the wrong frequencies and i am in need of one of these so I will be able to monitor the frequencies of my devices. Preferred specifications; Dual Channel,
I am going to repair an old radar and need an oscilloscope with 50 mhz bandwith. Is thisone any good? 5.7" TFT LCD 60MHz 2-Channel Digital Color Storage oscilloscope - free Shipping - DealExtreme
USB or PCI based data acquisition and display systems would cost you more than a benchtop oscilloscope. Try in your circle for any abandoned or old cathode ray tube based oscilloscopes from Industries which should serve your purpose. I assume you aren't looking for any high frequency applications.
Say I have a noise free square wave signal of 1 khz frequency and 5 v amplitude. The signal passes through some optical receiver and the shape of the signal becomes slightly distorted with some noise in it. I have a digital oscilloscope that has FFT. How can I use this FFT to detect the frequency of the noise so that I can separate the noise from t
This link could be useful : (Implementation of a low-cost PC based quad channel real-time / storage oscilloscope).
using this program u can use a PC as an oscilloscope using its sound card.
Another nice project with one
Hi all I want to make a oscillscop , using pic. It must save the waves and user can review them. it's good to use computer or only micro , ram & etc. If computer what "port" is your offer. thanks This project can be interesting to you:

is a good one but there is no schematics or binaries for free. free?? You dont even get them even if you buy the boards :D. Not even a single line of code or schematics are given for the digital oscilloscope project. Also he doesn't give schematics of the FPGA board you buy!!! The
I was thinking of building an FPGA based Digital oscilloscope that I can connect to my computer by RS-232. The information of building a FPGA based oscilloscope on is great and I think I maybe could build one, but I need a good freeware software that I can use to see the results. I'am not a good PC software programmer, that

The latest version of Virtual Breadboard (which is version 3) has been published free by its author. This is a nice emulator of several PICs and adds support for thirdparty software like the Bitscope oscilloscope software and also offers integration to MPLAB.
What is the use of an "Aux In" port on an oscilloscope? How is that used? Thank you!
it’s a simple, universal graphic interface for digital oscilloscope. Previous versions weren’t so universal. Contact with outside world is thanks to relative simple libraries The biggest limitations: - 1 acquisit

I wanna buy a oscilloscope. There are two option -1. Standalone oscilloscope, 2. PC based oscilloscope Which one should I chose? Is there any issue with PC based oscilloscope over standalone CRO in terms of accuracy?
Hello i need to make PC oscilloscope home make. please have me? thanks in advance
Hi there! Could someone kindly help me out with the matlab code for finding the frequency spectrum of a pseudo random signal. I've saved the data in CSV format from the oscilloscope (I've attached the file) and I now need the FFT! I did go through similar posts but the method explained is usually for a set periodic signal. Any help would be duly
How about Visual Analyser? It's free software that simulates various instruments including oscilloscope and spectrum analyser. Input is through the soundcard of your PC.
I am looking for an oscilloscope,for my Diy Audio bench (Own use),where obviously I cannot afford too much damage to pockets(<40k INR). preferably analogue one with 100 MHZ+ bandwidth having minimum 2 channels. Re-furbished or Used one in good working condition shall be given priority choice due to price factor. Anticipating your advice.
To generate a variable frequency up to 20kHz, use a free sound-card oscilloscope. (download is readily available) It will generate the output through the head-phone jack in your laptop. Feed this to a MOSFET and you are done! Or alternatively use a 555 timer with a variable resistor to adjust frequency. Again feed the output to the MOSFET. Perhaps,
Hello, I am looking of a soundcard oscilloscope program, but I need a special feature, and that is the functionality of external trigger. The most obvious solution I can think of, is the use of one of the two channels of the stereo input plug as a trigger input. Is there any software (free) that can do this?
