Actually I might go back and do the same one again, this time with a plot of the first stage of the pass band.
Little, in fact only the mains supply cable for a standalone AWG and that'll be behind a unit anyway.
You still need to tether it by USB when in Bode plot mode for the scope to take charge of it. But that can be done behind both units as 1004X-E's have a rear USB-A just for this purpose. Standalone's have USB-B on the rear but both these scopes and SDG's come supplied each with a A-B USB cable.
So effectively if using a Siglent standalone and all rear cabling there is one less cable on the bench than with SAG1021.
I've got the 1104 and the 1032 and was experimenting with the Bode mode. In the manual, it states that the 1104 can connect to the AWG via LAN as well, however, I tried it (briefly) and I couldn't get it to work. Are you saying that only the USB connection will work?

I can confirm that AWG control over LAN does not work with the current 7.6.1.20 firmware. Even worse, the AWG gets locked up and it takes quite some time until the scope finally reports that it failed to connect to the AWG.
I've already notified the responsible persons at Siglent.
EDIT: SDG device control over USB works.

Hi,
I've updated my SDS1104X-E with the new firmware but now I notice something strange on channel 4.
I can't see any signal with 50V/div, 5V/div, 1V/div, 200 mv/div (probe set to x10, with x1 the values are 5V, 500mV, 100mV, 20mV). To be more precise I can see the signal only for an instant after changing the V/div scale and then it disappears.
I never noticed this with the previous fimware so I think that is a firmware problem.
can someone check this? or can I try something to figure out what is going on?
Thanks

EDIT: SDG device control over USB works.Oh dear.....all this Bode plot connectivity worked fine even in beta test units.

Ok, so I tried the USB connection from 1104->1032 and it works. Then, for giggles, I went back and re-configured for LAN and it worked! I then unplugged the USB cable just to make sure and it still works. I don't know if I fat-fingered something the first time or what?
2) I also noticed that sometimes the last saved screenshot is not saved on the USB drive. it might be a result of some caching and I am not sure how to handle properly safe removal of USB drive since looks like 1204X-E does not provide any options for that.There has never been provision for USB 'safe removal' in Siglent equipment. Instead a saving bar graph indicator lets you see progress of the Save. A USB stick with a read/write LED can be useful to let you see the drive is not working.

When the file is saved on the USB drive, there is a message on the 1204X-E screen saying that the file has been saved. And if in 5 minutes after the message has been shown the flash drive is removed and the file mentioned in the message is not saved on the drive then I don't see how a a read/write LED can change it.
I wonder what kind of USB drives are supported by 1204X-E (I cannot find any info in the documentation). I have 4 different USB drivers ranging from cheap 4GB USB2.0 to expensive Samsung T1 USB 3.0 250GB and the only USB flash drive that works is the old and really slow 4GB USB 2.0. In all other cases after connecting a new USB flash drive nothing really happens (i.e. there is no message saying that the drive was connected) , but after 4-7 seconds there is a message on the screen saying - " USB flash drive removed." - at this moment the USB flash is still connected to 1204X-E but obviously not recognized.
May be there is some file system type/ drive size / power consumption limitations that we should be aware of ?

ThanksNow that the factory is back at work after Chinese new year hols and after checking they were aware of issues with v7.6.1.20, they've replied that they're trying to get a replacement firmware version out this later week.I found a bug related to displaying long IC2 decoded packets, I am running the latest X.20 firmware.
Look at the first column in the table, we cannot see the row 9:
.............If they can fit it in they'll try and address this too but their immediate focus is to fix the problem in v7.6.1.20
Thanks guys.

That's great! I'll also give v7.6.1.20R1 a spin tonight! Though, from the changelog doc included with the firmware, it seems only the top two items are in .20R1 and the rest was already in .20...
"Probes PP215".
I checked through the jpg "Probe Characteristics" that probe "PP215" has "200MHz" of "Bandwidth".
Please note that it is appropriate for the "Bandwidth" 100HMHz "SDS1104X-E" model, as it "exceeds the specifications" of this model ...
The model "SDS1204X-E" is for "200MHz" of "Bandwidth", and certainly needs a "probe" that "exceeds this specification".
Question: In the case of SDS1204X-E, should Siglent not supply with a "Probe" of at least "300MHz"?
The PP510 and PP215 probes are perfectly fine for the scopes they ship with. Higher bandwidth specification does not automatically mean better performance.
The table below shows the bandwidth for -1, -3 and -6dB as well as the transition times for various probes on a 200MHz SDS1202X-E. The real important parameters are the -1dB bandwidth and the transition times. The only probe that actually performs a little bit better than the PP215 overall would be the Pico Tech TA131.
