اسیلوسکوپ دیجیتال DSO Shell دارای نمایشگر رنگی DSO150

معرفی

اسیلوسکوپ  دستگاهی الکترونیکی است که امکان مشاهده ولتاژ را فراهم می‌کند. غالباً مقدار ولتاژ به صورت نموداری دوبعدی نمایش داده می‌شود که محور افقی، زمان و محور عمودی آن ولتاژ است. از نوسان‌نما عموماً برای نمایش دقیق موج استفاده می‌شود. علاوه بر دامنه، معمولاً نوسان‌نماها قادر به اندازه‌گیری و نمایش دیگر پارامترها مانند عرض پالس، دوره تناوب و زمان بین دو حادثه (مانند وقوع دو پیک) هستند.

Introduction

DSO Shell (DSO150) has similar bandwidth as the popular DSO138 kit, but contains significant improvements to the structure, assembly, and operation. One major difference is the DSO Shell comes with a full molded plastic enclosure. The panels are flexible for easy user installation and modification. A rotary encoder has also been added to make parameter adjustment quick and painless.
The sensitivity of DSO Shell has also been improved over DSO138. DSO Shell is capable of 5mV/div through 20V/div.
The 2.4" color TFT LCD display and microcontroller are now mounted on the same board (mainboard) to avoid using inter-board pin-headers. The analog channel is on a separate daughterboard PCB to provide better separation between the analog and digital portions of the design. Without the analog daughterboard the mainboard is actually a general purpose control board that can be used in many other applications. Aside from a few through-hole components, the mainboard is fully assembled. It is also factory-tested before shipment to ensure your kit will function as expected.
IMPORTANT: 9V DC input power is required. DO NOT EXCEED 10V! If using a wall wart, test the actual output before powering your scope. It WILL permanently damage your scope to use higher voltages! We're sorry for yelling. But it is important.
Detailed assembly instructions, troubleshooting guide and schematic are provided.
