Logic Analyzer with High Performance

Figure 1 

The design of the device pertains the creation of a logic analyzer that views the voltage of logic electric signals that are normally too fast to be measured by a voltmeter.

The sampling rate or the maximum number of samples that can be recorded per second is the main key point that makes a logic analyzer better than another. Viewing the logic analyzer from a functional point, it records the states of logic signals which usually occur after some triggering condition is achieved, and displays the recorded signals on a screen for in depth analysis.

The device was named as Scanalogic which is simple and yet effective logic analyzer for beginners who are doing some debugging and analyzing of projects. As high as 4 Million samples per second is the sampling rate used by this device. This is due to the 4 channels which are used as transmission lines. The project is a combination of ATmega16 microcontroller and a NAND gate.

The samples at the desired sampling rate are recorded by the hardware which sends the samples to the PC application through the UART port of microcontroller and the RS232 port of PC.
