Product Description

Product Introduction
This series of instrument is a signal generator with features such as highly stable, broadband and multi-function .The design of appearance is strong and elegant. And it is easy to operate, could directly generated sine wave, 
triangle wave, square wave, ramp, pulse, and has VCF control functions. TTL / CMOS can be as synchronized 
output with the OUTPUT. The adjusted Waveform is symmetry and have reverse output, DC level can be adjusted continuously.
 Frequency meter could be as the display of internal frequency and measure the outside frequency. 
It is particularly suitable for teachings, scientific researching and experimenting of electronic and pulse circuits.
