1. Purpose
Embedded board에 digital storage oscilloscope의 triggering 기능을 hardware 및 software를 사용하여 설계 구현하는 것이다. Interface board에 triggering hardware를 구현하고, 이를 구동하기 위한 PC및 embedded board에 software program들을 구현하여 triggering 기능을 완성한다.
2. Problem statement
Design and implement an oscilloscope triggering subsystem, which generates the trigger pulse. The triggering function includes channel, level, and polarity, with arguments suitable for the oscilloscope specification. The Command Client program is extended with the following “"Trigger”" Commands:
% Trigger channel n // n = 1 or 2
% Trigger level l [mV] // l = -1000 to 1000. “"mV”" is optional.
% Trigger polarity p // p = + or . See Note
Specifications for the trigger circuit are as follows:
Power
Analog power supply: +5 V and -5 V. 500 mA max.
Channel signal input (analog)
Channel source: Ch 1 (amplified signal by PGA), Ch 2.
Channel signal voltage: -1 V to 1 V for both channels.
