NANAO ELECTRIC Manufacture NAGP Frequency Signal Generator
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.
