Performa01, thanks for the input. --- Quote ---That it fails to apply changes in max. record length without a detour (nice finding, @kcbrown!) might add to the problems, but it's certainly not the only one. --- End quote --- Can you explain exactly what you believe these other problems are with the SDS2000X+ in terms of its trigger engine? Thanks! |

Dear all, A new episode is ready on the comparison series, now on Bode Analysis. On paper, the Siglent SDS2000X Plus has the best cards of our three instruments. Is this true? (Spoiler: yes, but you need to be very patent, and the specs don’t tell you the full story…) The updated comparison document is available here. |

See reply #3274 in thie thread below: https://www.eevblog.com/forum/testgear/siglent-sds2000x-plus-coming/msg4061779/#msg4061779 Topics 3 an 4 in that post might not be valid though, as I only saw them once after a FW-update and wasn't able to reproduce it after a reboot. |

A few remarks: * The Bode Plot in the Siglent is slow, especially at low frequencies. There might be reasons for this, like frequency selective detector and averaging for precise measurement results even at very low input signal levels in high dynamic range measurements. * Your simple tests did not reveal anything about the dynamic range of the measurements, where I expect the up to 120 dB dynamic to be another significant advantage for the Siglent. And it's mainly the dynamic range that makes up for a useful analysis tool in this area. * Your complaint about not being able to set fine steps for the amplitude axis has aready been addressed in the SDS2000X HD and will be available in the next SDS2000X Plus firmware. We can now set the scale in 1 dB increments. * Your complaint about not being able to have a look at the time domain view has aready been addressed in the SDS2000X HD and will be available in the next SDS2000X Plus firmware. |

@Performa This time you were faster.. :-DD Just to add, if you watch triggering lights on Siglent at very low frequencies, you will see it takes 5 measurements and than averages that data point. Like Performa said, it uses frequency selective algorithm, and together with averaging, it will have much improved software gain and it will be resilient to outside interference. That makes it have very good dynamic range and more robust if you are not working in a Faraday cage. |
