Characteristics: |
|
The new FG708S, 8MHz is designed with DDS techniques (direct digital synthesis) and comes with modulation capabilities and improved quality waveforms as opposed to convectional designed DDS FG’s while generating small signal has noise. FG708S can generate small signal down to 1mVp-p with ultra low distortion and noise. Apart from comprehensive standard features such as digital setting of linear and log sweep function, trigger, gate function etc. FG708S also has FSK and PSK modulation functions which can satisfy modern telecomunication applications.
With such powerful functions, FG708S is even provided at a very cost effective price, thus, users are provided with pure waveforms unlike VCO designed function generators. |
