توضیحات
مهمترين دستگاه در تست تجهيزات الکترونيک فانکشن يا سيگنال ژنراتور (signal generator) مي باشد. فانکشن ژنراتور يک توليد کننده سيگنال يا شکل موج مانند سينوسي، مربعي، مثلثي و... با دامنه و فرکانس هاي مختلف مي باشد. بطور مثال توسط يک فانکشن ژنراتور ميتوان شکل موج مربعي به دامنه 5Vpp با فرکانس 12KHz را توليد کرد. سپس از اين سيگنال بعنوان منبع تغذيه در مدارات الکترونيکي، مخابراتي و... استفاده کرد. براي عيب يابي و طراحي در مدار نياز به سيگنال قابل کنترل داريم تا بتوانيم بهترين عمکرد از مدار را بدست آوريم.
کاربردها :
* مراکز تحقيق و توسعه
* آزمايشگاه هاي آموزشي مانند آزمايشگاه الکترونيک در دانشگاه ها
* تعمير تجهيزات الکتريکي و الکترونيکي
* تست پاسخ دهي و تست تحريک، بررسي خصوصيات پاسخ فرکانسي و تزريق سيگنال داخل مداري
