一、概述
本儀器采用單片機波形合成發(fā)生器產(chǎn)生高精度，低失真的正弦波電壓，可用于校驗頻率繼電器，同步繼電器等，也可作為低頻變頻電源使用。
本儀器具有讀數(shù)直觀，精確，性能穩(wěn)定，操作方便等特點。關(guān)鍵器件采用進(jìn)口元件，是一種有著較高性能價格比的試驗儀器。
二、基本原理
工頻信號發(fā)生器，主要由數(shù)字波形發(fā)生部分、功率放大部分、以及中央控制單元等組成。通過前面板控制數(shù)字波形發(fā)生單元產(chǎn)生一個頻率及幅度非常穩(wěn)定的數(shù)字合成的正弦波，然后送到功率放大器進(jìn)行放大。*后經(jīng)過輸出切換及短路保護后輸出。中央控制單元則負(fù)責(zé)測量輸出頻率及輸出幅度，并監(jiān)視整個系統(tǒng)的工作狀態(tài)是否正常。

One. Overview
This instrument uses single-chip waveform synthesis generator produces high-precision, low distortion sine wave voltage, can be used to calibrate frequency relays, synchronous relays, etc., can also be used as low-frequency inverter power supply.
This instrument has a reading intuitive, accurate, stable performance, easy to operate ａnd so on. Key components of the use of imported components, is a high performance ａnd low cost of the test equipment.
Two. Basic principles
NAGP Frequency signal generator, mainly consists of digital waveform generation part, power amplifier part, ａnd the central control unit ａnd so on. Through the front panel control digital waveform generation unit produces a very stable frequency ａnd amplitude of the digital synthesis of sine wave, ａnd then sent to the power amplifier for amplification. Finally, after the output switching ａnd short circuit protection output. The central control unit is responsible for measuring the output frequency ａnd output amplitude, ａnd monitor the work of the entire system state is normal.
