Siglent SDG6000X Series Arbitrary Waveform Generator Review, Teardown & Experiments

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.

This comprehensive review is organized as follows:

00:01:11 – Siglent SDG model overview and comparison
00:03:10 – Front and back panel overview
00:06:24 – Full teardown and analysis of the instrument archietecture
00:18:19 – GUI overview, menu structures and built-in functions
00:22:31 – Waveform phase and amplitude accuracy, characterizing a 180-degree hybrid
00:30:42 – Large-signal generation, ultra-sound experiment and range measurements
00:36:38 – Pulse generation performance, spectral content and low-pass filter measurements
00:44:07 – THD measurements, harmonic generation, Two-tone TOI measurements using waveform combine function
00:50:30 – PRBS pattern generator, ISI measurements and eye-diagram impairments using waveform combine functions
01:01:57 – I/Q modulation and waveform creation using EasyIQ as well as superheterodyne up-converter measurements
01:10:44 – Concluding remarks

    I have heard much about the Siglent SDG6000X and people say the product is good. I read the article and got an exact idea about the pros and cons. Thanks for giving us a detailed review.You can also visit, https://driver.support/samsung-printer-driver-support/

    Thanks for the review. I wonder if you could tell me if any of the SDG6000x series are able to output different user-defined arbitrary waveforms on each channel simultaneously?

    Great review! It’s amazing how much bang for the buck you get from Rigol, Siglent and others. I still use the Tektronix 2215A I bought in 1982 (?) for around $2K. My $400 Rigol 1054Z blows it away, but sometimes an old-school analog ‘scope is the right tool.
