Based on your last info, my only conclusion is that the scope must be routing the IP packets between both IP stacks internally.

If you get me a 3rd IP than I'll be amazed!!!  :-DD
That just might be possible too !

2 saved settings then turn DHCP ON to get a 3rd auto negotiated IP but don't Save it.  :P

After thinking about it maybe the USB wireless adapter is getting the DHCP IP 192.168.1.168 and the scope is using the static IP of 192.168.1.212. Also the USB wireless adapter has its own MAC address different from the scope.

I thought you already knew that!  The question is you accessing both IPs with just one connection.  The scope behaves as having an internal network switch, as you configured both interfaces in the same network. Nice.

Nope, it can only use one or the other not both at once.

Yes, but through one interface you can "see" the other...

Which poses a problem: if you have all the network configured with DHCP, connected to the scope only via WIFI, but you have a static IP in  the scope's ETH interface (as seems to be the case), one can have a problems of collision between IPs. Must choose DHCP pool with care or have both scope's interfaces configured with DHCP.

It might seem so but what you cannot see from MikeLud's pics when in webserver mode, only the settings relevant to the active connection type selected on the instrument (WiFi or LAN) can be seen. To see the other it must be selected, working and active.

I don't want to insist, tautech, but the fact is he can ping both interfaces at the same time and reach the webserver via both IPs at the same time .

Odd display glitch on SDS1104X-E
« Reply #1457 on: July 29, 2019, 08:32:26 pm »
A few days ago I was watching the separation of some pulses, and started getting very odd display glitches. They lasted for around three seconds and repeated at a similar interval. They continued to repeat until I adjusted the trigger level, just a touch. Then things would be fine for a while (10-15 minutes) but the glitches returned. I'm certain there was nothing like the display in my signals! I made no other adjustments the whole while and wasn't doing anything 'clever' with the 'scope.

It hasn't happened like that since, although I do see an occasional (every few minutes or so) very quick glitch, as if a single frame of the display has gone a bit haywire. Blink and you miss it.

Has anyone seen anything like this? I'm a bit concerned my new 'scope is faulty.

This is the sort of display I was watching, with the edges moving relative to each other:

798009-0

And this is what the glitches looked like. That first one's a killer:

798027-1

798021-2

798015-3

someone here with SAG1021 and 6.1.33 Firmware installed?

When i try to import wave from my SDS1204X-E, in EasyWave error popups and the wave is corrupted:

Another interessting behaviour is, i can save waves created in EasyWave in SDS Memory, they can be selected later from the read/send wave menu in EasyWave. I can see them over Telnet in usr Directory as well. Sure, they can't be selected from menu on SDS, nor deleted, but they has been stored and can be still selected with SCPI or EasyWave after SDS has been rebooted.

Based on Performa01 review "There is just no writeable permanent memory in this device, so we need to use an USB stick to store the waveform on the PC." -> https://www.eevblog.com/forum/testgear/siglent-sds1104x-e-in-depth-review/msg1432667/#msg1432667

and Siglent's not very clear Statement -> https://www.siglentamerica.com/operating-tip/waveform-capture-regeneration-using-easywave-software-siglent-oscilloscope-awg-option/

i thought one can't save waves with EasyWave on SDS, but that seems to be not the case, at least with 6.1.33 Firmware.



To read them via SCPI call

STL? user

which returns for the two i saved "STL WVNM,wave,User", where "wave" and "User" are wave names created in Easy Wave



To call such user created wave from SDS Memory via SCPI one have to call it via:

C1:ARWV NAME, User

or

C1:ARWV NAME, wave

and the wave will get selected

How awesome is the new FFT in firmware version 6.1.33? Answer = very awesome.
Yep.

Just revisiting FFT to set the scope up properly for an upcoming industry display.

Signal= SSG3021X LF output 1MHz 0dB terminated into a Tek 50 ohm BNC feedthrough.

SDS1104X-E FFT with full Marker table ON. All 8 markers used.
Note the fundamental (marker 2) @ 0dB via unknown BNC cable and Tek termination is just 25 mili dB down.

0Hz.

I only did it like that to show the FFT span was from 0-10 MHz while we all know the first marker wouldn't be sitting @ -22dB if the sweep had started at 100 Hz as there wouldn't be such a peak.
You can just see the frequency graticules across the top of the plot.
Markers were manually placed but if selecting Peak Markers from the FFT menu they all will be pushed right one peak and 0 Hz wouldn't have a marker on it.

Make sense ?

When will there be a firmware release update that fixes the lack of a trigger point in the data file?

I am happy with the scope except for this fundamental flaw in the data file structure.
