SIGLENT SDS1102CML - First Impressions
Pippy:
Just bought one of these scopes (the SDS1102CML) and it's not to bad I guess. Firmware could be better but se-la-vie.
They have a problem with their software channel filter, at lower frequencies rather than do proper low-pass-filtering it slightly rounds off the edges (which is correct) but then cuts the amplitude down (which is wrong).
This is looking at the scopes own 1kHz reference ..

Can anybody who has a SIGLENT SDS1102CML dso help me?
Please save the data from channel 1 from the scope's calibrator signal with the horizontal position on 250us in LongMem mode to a file
The file size would be 2M
I'd like to post it to me
Thanks

Look at this two signals. The difference is longmem on and longmem off.
800khz / 20khz = 40, but the samplingrate was 500KS/s and 25MS/s
25 / .5 = 50
There is a bug in the FFT calc.

Agreed - I noted the same discrepancy in my review of the Siglent/Atten 'scope using the 3.x firmware. So this is an issue they did not fix in the 5.x firmware? When I tested this on the Rigol DS1102E, I noted that the Rigol simply switches back to short-mem "Normal" mode when you enter FFT mode.

Again, a few questions about SDS1072, not 1102, sorry (I believe those are 99% identical scopes anyway...):
1) How can I use RS232 for some practical, useful and fun (of course) things?
2) In order to use EasyScopeX, I have to download a huuuuge NI-VISA package :((>600M?) - Easyscope is just a few MB, so how can I use this software with minimum additional software - what should I download?
What other software can I use with SDS? Can I use LabView (it already includes NI-visa) - is it better than EasyScope (I don't plan to do nothing special; to see waveforms on PC monitor, change colors of images, simple measurements (but on bigger screen :)), simple analysis. If it is better than ES, I will rather downl.... :-[ hmm... buy full version of LabView instead of ES+NI-VISA!
3) Does somebody know how to calculate/estimate number of waveforms per sec (I don't have any fancy equipment!)?
4) Can I kindly ask, if somebody has ECG simulation image (in scope's format) that I can put on USB-stick and see it on my scope, I will be veeery grateful if he/she puts that file here!?
TIA!
