I am in the market for a arbitrary signal generator, 2 channel, deep as possible memory, supports modulation, and so on. Any one have a comparison of Siglent SDG2000x and the Rigol DG1000Z? or thoughts.

Thanks,

Wylie

Hi Wylie,

I know several of our USA distributors have SDG2000X generators on order. The first large shipments are scheduled to arrive in mid-October. Some smaller shipments will arrive before then but I am guessing most of those units have already been sold. If you want to contact us at

[email protected]we can point you towards one or more of those distributors.

The sample rate for the DDS circuitry is, in fact, slower than 1.2 GS but the D/A converter is clocked at 1.2 GSa/s and interpolates (4X) the final waveform to smooth it and reduce distortion. This technique is described in a application note that will be available soon on Siglent's web site. We have applied for a patent on this technique.

Finally, the EasyWave software is fine for what is was designed to do - general purpose arbitrary waveform generation and editing, mathematical formula waveform generation, dual waveform math functions, etc. it was not designed to compete with some other software packages that have built in standard functions such as pulsed radar waveforms, Lorentz functions, etc.
