For those who wish to parse the response of the WF? ALL query, I've found this document, especially the Waveform template section to be very useful.
https://wiki.epfl.ch/carplat/documents/PDF/LC6800A_WM-RCM-E_Rev_D.pdf
With this documentation it was not to hard to get VOffset, VFactor data etc. from the response, instead of having to query them separately.
Also there're some fields with sizes in them, which can be used to get to the waveform data in a robuust way. Also knowing how many bits (1 of 2 bytes) the samples are. I don't think hires and averaging samples can be fetched with extra bits, but if it could these fields would be vital.
I still have the issue that WFSU NP,xx limits the number of point but results in having a single repeating value in the waveform data
Also would it be nice if segments could be queried separately using WFSU SN,xx. Now I'm using a different approach, which works, but I'm essentially setting gui stuff, with (usable) side effects.
Hi,
Just sharing some observation.
Plugged USB stick 16GB, works great, saving images, recognized after soft power-down, all ok, but,
after blackout (during standby - soft power down) usb still plugged in but after boot usb did not recognized.
After reboot without usb stick, plugging again usb all ok. Tested two times - unplugging from power in stand by mode.
Like scope didn't like being unplugged from power with usb plugged in.
Some new probe commands that hint at digital probes
My wish, besides fixing the lack of trigger reference error in the CSV data, for a future firmware update for the SDS1104X-E is an addition to the XY mode. I would like to see an XYZ mode in which channel 3 or 4 could be used to vary the intensity of the trace. This way it could mimic the functions of analog scope in the ability to vary intensity and blank the display, and also be used to mimic and analog monitor fixing older CRT based gear.
Lead me not into temptation, just point the way and I'll find it myself!
Dang nabbit you guys you pointed the way and kicked me over the edge and even with all the nay sayers I still ordered one of these critters SDS1104X-E. Due in 2 to 4 days.
This all started when I was offered a Rigol DS1102E from one of my clients that was barely out of the box when her husband passed away. But it is only two channel! From there I looked at the Rigol 1054Z but the Siglent SDS1104X-E was only $23 dollars more.
I have been looking for a 4 channel scope for quite awhile. Most of what I need the scope for is three phase power work, testing RPC's (Rotary Phase Converters), VFD's (Varible Frequency Drives)
etc so I need the ability to be able to show three phases on the screen at the same time to compare them.
Still doing my homework as to what other probes I will need besides the stock probes.

Would be nice to know if the isfe probes can be used to isolate all four channels. Case in point 3 phase Delta Configuration where there is no common ground, as opposed to Wye or Star configuration where there is a common ground point.

One thing I can't confirm as I haven't checked is if 2 ISFE units will mount side by side onto the 4 BNC inputs and you'd need to check with one of our tech support people to confirm they do.

Looks too wide to connect two units directly side by side. I wonder if they could be attached with very short coax cables with appropriate bnc connectors on each end without hurting performance.
edit: just realised one of them could be connected upside down so maybe they would fit ?
Given the limited 1MHz bandwidth of these units there should be no difference in the resulting measurements if they are connected with a pair of short BNC cables. That seems like the obvious solution to me.
Plus it looks like the units will apply some shear stress on where the BNC connectors soldered to the PCB on the scope. Thus using short BNC cables seems like the best choice.

Walter Townsend, TTDrWhile the stock probes are rated to 600V @ 10x it would be wise to get some fixed 100x probes not only for their higher voltage rating but also the additional protection they offer the user and the scope.
At the sort of frequencies you'd encounter the cheap ones from eBay or Aliexpress would be fine.
This of course presumes you can probe with a common reference point (mains ground) for all your work however when you can't either 2 units of Siglents 2ch ISFE or a set of differential probes are the preferred and safe solutions.

P4250 or CP-3308R which would couple to the Siglent better.
Suppose a stupid question. But is there any reason a siglent scope would not support an externally powered usb hub.
Hmm, looks like the voltmeter and measurement histogram, and zone triggering features are buried in there too, however they don't seem to have menus. looks promising. Any word on them Performa01? or are they staying 5000 exclusive?
