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 input 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.
