Homemade Digital Oscilloscope

ATMega162 based homemade digital oscilloscope project with a sampling rate of 40MSPS and 5MHz maximum input frequency.

An oscilloscope is one of the most important tools that should take place on a electronics hobbyist’s workbench. But most of the commercial oscilloscopes are often too expensive. This LCD screen homemade scope features;

• 40 Mega samples per second
• 5 MHz input frequency
• 10 MHz max. frequency displayed without aliasing
• 20 MHz input circuit bandwidth
• 40mV/div sensitivity
• DC coupling
• 10 KOhm input impedance
• 240×128 total, 200×125 trace resolution
• 9V – 1A power source
• Digitally adjustable trigger and trace offset.

Main part of the circuit is Atmel ATMega162 microcontroller. OPA2652 and RF filter pair sets the BW to 20MHZ. 8 bit 60MSPS ADS830 IC is used for the analog to digital conversion. The digital output is connected to a high speed FIFO memory.

USB programmer for Atmel AVR controllers

USBasp is a USB in-circuit programmer for Atmel AVR controllers. It simply consists of an ATMega88 or an ATMega8 and a couple of passive components. The programmer uses a firmware-only USB driver, no special USB controller is needed.

Features

• Works under multiple platforms. Linux, Mac OS X and Windows are tested.
• No special controllers or smd components are needed.
• Programming speed is up to 5kBytes/sec.
• SCK option to support targets with low clock speed (< 1,5MHz).
• Planned: serial interface to target (e.g. for debugging).
