More and more experimentsare now ‘PC-assisted.’ Alsoconventional acquisition systemsare very expensive. Since portablePCs are today common and a USB linkis a better solution than an old ISA bus,here we present an oscilloscope usingUSB port of the PC that operates at upto 10 kHz with ±16V input voltage. Ithas much more improved features thanthe PC-based oscilloscope and LEDscope for audio servicing published inEFY Dec. 2002 and Electronics ProjectsVol. 8, respectively. The oscilloscopeuses IC PIC18F2550 from Microchipas the main controller ....etc

please help me to make an oscilloscope using avr with sample rate of more than 1000s/s . but i dont need very high rate. maybe 20ks/s is enough for me and the price is much more important.please help me

Abstract:
This is one of great project based on AVR microcontroller. It use ATmega32 as processor and LCD 128×64 pixels for display. If you need to measure low frequency i thought this project, AVR oscilloscope, will be usefull. Maksimum frequency for AVR oscilloscope is 5 kHz (square signal), other signals (sine or triangle) the frequency is lower ( almost 1 kHz) for having clear view of the signal. Voltage input range is 24V AC / 30V DC.
This project use C language and CODEVISION as compiler. So, it will be more easy to understand t ....etc

DIGITAL STORAGE OSCILLOSCOPE

What is an OSCILLOSCOPE ??
An oscilloscope (also known as a scope) is a type of electronic test instrument that allows observation of constantly varying signal voltages, usually as a two-dimensional graph of one or more electrical potential differences.
A Digital Storage Oscilloscope (DSO)
A DSO is also like a conventional oscilloscope except that it uses digital memory to store the waveform. Thus it first digitizes the input analog signal by an analog to digital convertor and di ....etc
