Brief introduction of signal generator
The signal generator is a desk type electronic instrument. It has a keyboard
distribution that is easy to operate and a 7.0-inch TFT color liquid crystal display
screen with high definition; a display interface comprises proper settings and prompt
messages; USB, LAN and GPIB communication interfaces are provided; and a
virtual terminal can be used for display, control and remote network access. The
signal generator can be widely applied to various fields such as science of education,
enterprise research and development and industrial production, etc.
Main performance characteristics:
Excellent phase noise: <-115dBc/Hz@20kHz
Large dynamic power output: -127dBm ~+13dBm (available from
-136dBm)
Rich Modulation mode: AM, FM, ΦM in diameter and pulse
modulation
Multiple RF scan output combining frequency and amplitude.
Low frequency signal output, namely sine, triangle, square, sawtooth
wave,etc.
