And lastly. With the coupling set to ground. Do they read better or worse (suspicious procedure may have changed)
* | Channel 1 | Channel 2 | Channel 3 | Channel 4 |
5 mV/div | -837.58 μV | -1.79 mV | -5.24 mV | -553.21 μV |
10 mV/div | -1.17 mV | -2.83 mV | -6.25 mV | -751.54 μV |
20 mV/div | -1.50 mV | -3.20 mV | -6.40 mV | -1.31 mV |
50 mV/div | -3.74 mV | -4.00 mV | -4.31 mV | 0.0 pV |
100 mV/div | 0.0 pV | -4.00 mV | -4.19 mV | -4.00 mV |
200 mV/div | -8.00 mV | -45.71 nV | 0.0 pV | -8.00 mV |
500 mV/div | -6.34 mV | -6.83 μV | -114.29 nV | -15.43 mV |
1 V/div | -4.21 mV | 0.0 pV | 0.0 pV | -649.60 μV |
2 V/div | -159.94 mV | 150.17 μV | -616.46 μV | 0.0 pV |
5 V/div | -185.12 mV | -47.52 mV | -20.29 μV | -28.29 μV |
10 V/div | -392.78 mV | 0.0 pV | 0.0 pV | 0.0 pV |
20 V/div | -1.56 V | 85.96 mV | 25.14 μV | -8.00 μV |
50 V/div | -2.86 μV | 0.0 pV | -91.43 μV | -148.57 μV |
100 V/div | -776.38 mV | 0.0 pV | -3.42 mV | -1.17 mV |
Changing the attenuation to 1X doesn't really do anything to improve the situation. The range automatically changes from 2V/div to 200 mV/div when I go from 10X to 1X, but if I re-adjust the range back to 2V/div, I observe the same large offset (on channel 1) of around -160 mV.
My heart is set on 4-ch 200MHz or more scope by the end of the Summer, so I'm budgeting for the SDS1204
Sorry for asking again, but are lot's of people hacking the 100MHz version to the 200MHz without any problems ? There's a big price diff for me.
I want a 4-ch scope, but I don't want to settle for 50-70-100MHz like the nice Rigol's. I want to be higher than that level, as my "base" scope. And then some day I'll save up for a 2-ch thats a lot faster than my base scope.

Wait a minute, the SDS1104 only has the single 1GS/s ADC , but the SDS1204 has 2 of them ? Is the memory and the rest of it the same ?
±(1%* Offset+1.5%*8*div+2 mV): ≥2 mV/div
±(1%* Offset+1.5%*8*div+500 uV): ≤1 mv/div
The only exact way i can phrase it is later firmware versions may tweak it.
I'm not sure why it happens, but these artifacts was added at the time when Siglent released new X-E model. So, I think they both may share the same signal processing algorithm.
I'm a bit ashamed to admit, but I'm having trouble reading the specification for DC offset accuracy in the datasheet, which states:Quote from: Siglent datasheet±(1%* Offset+1.5%*8*div+2 mV): ≥2 mV/div
±(1%* Offset+1.5%*8*div+500 uV): ≤1 mv/div
I don't fully understand how to calculate the maximum permissible DC offset, for example for the 2V/div range (which is: ±(1%* Offset+1.5%*8*div+2 mV)) . Could someone enlighten me? When the channel is shorted, the input signal is 0 V, does that mean the offset should not exceed 2 mV?
trace is clearly separated from the zero position marker.
In the center of the screen, there's a very visual notch/stair in the waveform, just at the trigger level. Is this to be expected? I can't really understand why, but it does appear to be just a visual artifact.
What i was after was a command that would put it in a bode plot mode with the parameters exposed so I could set the center, span, etc via scpi,Officially; Bode plot SCPI command set: totally unsupported at this time.
Rerouter would like it, please raise hands who else.
I am curious if this is normal for this model.
