Shahriar @TheSignalPath reviews the SIGLENT SDG6000X Series of arbitrary waveform generators… per The Signal Path website (http://thesignalpath.com/blogs/):
In this episode Shahriar takes a close look at the newly released Siglent SDG6000X Series Pulse / Arbitrary Waveform Generator. SDG6000X is a series of dual-channel Pulse/ Arbitrary Waveform Generators that feature up to 500MHz output frequency, a maximum sample rate of 2.4GSa/s and 16-bit vertical resolution when used as a function generator. The particular reviewed model is the SDG6052X which is the top-end model.
The full teardown of the unit reveals the internal architecture of the instrument, DAC / FPGA interconnect as well as the output amplifier structure. Although the limitations of the FPGA prevents the instrument to operate at full 2.5GSa/s in arb-mode, the instrument is capable of providing complex modulation up to the full 500MHz signal bandwidth.
