High Precesion Function Generator  DDS

Dual Channel Function/Arbitrary Waveform Generator is a multifunctional signal generator product

integrating Function Signal Generator, Arbitrary Waveform Generator, Pulse Signal Generator, Noise Signal Generator, Counter and Frequency Meter with excellent cost performance. This instrument adopts large scale CMOS integrated circuit and high speed MCU microprocessor. The internal circuit uses SPXO as the basic standard to guarantee the stability of signals. Surface mounting technology improves interference immunity and operational life span. 

This instrument has double channels can output 31 preseted DDS signals including Sine, Square, Triangle(Ramp), Rise Sawtooth, Fall Sawtooth, Lorenz Pulse, Multitone, Noise, Cardiogram, Trapezoidal Pulse, Sinc Pulse, Narrow Pulse, Gauss White Noise, AM, FM, Step and user-defined waveform. It can also output TTL electric level. Both channels are completely independent

It has friendly human-machine mutual interface. 2.4 inch TFT Color LCD with 320×۲۴۰ resolution can display all the parameters of both channels and current functions of all buttons . Shortcut keys simplify all complicated operations and save time. Users can be proficient after several minutes practice.

The advantages of this instrument in signal generating, waveform sweeping, parameter measurement and other fields, make it to be the ideal equipment for electronic engineers, laboratories, industry producing line, university, R&D institutes and so on

فانکشن ژنراتور در بسیاری از حوزه ها از جمله شبیه سازی سنسور های شتاب سنج ، کنترل نرخ نمونه برداری کارت  DAQ و پیدا کردن نرخ نایکوست کارت دیتا اکوزیشن و همچنین مهندسی پزشکی کاربرد فروان دارد برخی از این فانکشن ژنراتور ها که از نوع آنالوگ هستند دقت بسار پاءینی دارند و عموما دارای حافظه داخلی نیستند و تعداد شکل موج آنها محدود است مانند XR2206 اما در DDS اینگونه نیست این مدل را فانکشن ژنراتور دیجیتال می گویند و دارای دقت ۰٫۱ میکرو هرتز است و همچنین می تواند ۳۱ شکل موج متوع ایجاد کند و دارای ۱۶ حافظه داخلی است که می توانید از آن برای تولید شکل موج های دلخواه خود استفاده کنید. علاوه بر این این دستگاه به عنوان فرکانس متر نیز مورد استفاده قرار می گیرد. و به دلیل مصرف کم می توانید آن را به راحتی با باطری مانند پاور بانک راه اندازی کنید.
