content: Just ordered an SDS804X HD scope and researching what is needed to 'Upgrade' it for more memory. If I understand correctly, the SDS800X series uses the same hacking script that worked for the SDS1104X-E scopes. What is not clear to me after searching the forums is whether the options listed in the keygen code script are the same for the new SDS800X HD series and if the 50M -> 100M memory upgrade is it's own option or is simply related to the upper models... So modifying the BW to 200MHz would result in the scope identifying as an SDS824X HD with 100M memory. I did not observe any memory option code in the script.Does the Python script require any modification for SDS800X specific options or does the script work exactly the same way? I don't necessarily need the full 200MHz BW, but would like the ability to have more memory. Of course if the two features are related it's not a bad thing to get both lol.TIAEdit - what are people entering for the model #? "SDS800X-HD" ?# Enter here the basic model# You get this by running "MD5_PR?" at the SCIP prompt# A sample: You have the SDS1104X-E than enter "SDS1000X-E"# Some more basic models: "SDS1000X-E", "SDS2000X-E", "SDS2000X+", "SDS5000X", "ZODIAC-"Model = 'SDS1000X-E'

content: Hi TomKatt!QuoteYesI used this:https://www.eevblog.com/forum/testgear/siglent-sds-sdg-hack-scriptThese lines I changed to:Model = 'SDS800X-HD'...bwopt = ('70M', '100M', '200M')...otheropt = ('AWG', 'MSO', 'PWA')I got my scope already improved to 200M, but compared the retrieved (command "MCBD?") key for the 200M option with the result of the script - bingo!Coming from a 804 I would improve stepwise: 70M > 100M, Reset to factory default, 100M > 200M, Reset to factory default, self calibration, enjoyMy scope identifies as "SDS824X HD"HTH Thomasedit: otheropt

content: Got my SDS804X HD today... The upgrade script worked perfectly! Out of precaution I did upgrade it in steps 70 -> 100 -> 200 and then ran a calibration. My scope now identifies as an SDS824X HD. I have my own LA and AWG gear so have no need to enable those features in the scope.Note to future owners - the serial number string is case sensitive. I originally entered the serial number using all caps but noted that the calculated code for 70Mhz did not match the code returned by the MCBD? query - knowing it needed to be the same code I then pasted my serial number as displayed on the SCPI Home screen and ran the script again. When the script code for 70MHz matched my scope's code I then proceeded to upgrade.Thanks again!

content: Well, that turned out to be easy. Just followed the script to get the scope id, serial number, and model number and edit those into the script. I did as others suggested and upgraded from 70M - 100M, default to factory, then 100M to 200M, default to factory. It now identifies as an 824 rather than an 804. Currently it is running the self-calibration.One thing that I noticed -in the Acquire menu, I could still only choose 50M as the maximum memory depth (single channel),but when I adjust the horizontal timebase, I see that it is going up to 100M points.On edit: after rebooting and doing a self-calibration, it is now showing 100M as the maximum option under Acquire - Menu - Max Memory Depth. Interestingly, it no longer shows 50M as an option in this list (when single channel is enabled - of course it drops to 50M when two channels are enabled).Very cool that this is so straightforward to do. Thanks to those who put together the script and gave instructions!

content: I have no way to test this, but I find it very interesting that upgrading to 200Mhz apparently also increases waveform capture rate by 50% (80K -> 120K wfm/s) in addition to doubling the memory from 50M -> 100M... Is there some correlation between memory and capture rate or do the <200MHz models have some software performance constraint?

content: Quote from: tautech on June 06, 2024, 08:06:16 pmYes - that's where I obtained the specs. But I'm still amazed (confused) that in addition to bandwidth, the performance is also increased simply by software. My question is if the additional memory allows the capture rate to increase as well?Edit - I guess that bandwidth itself could be considered a performance measurement, and other products have been similarly constrained to differentiate model capabilities...

content: I've got an SDS 1202X-E which is their genuine 200MHz scope and just bought a SDS804X HD.Successfully re-licensed the latter to 200MHz, though I went directly to the 200MHz key without any factory resets between, in fact if you stick a 200MHz signal in you can see the amplitude change live between pasting the SCIP MCBD keys, I switched between 70, 100 and 200 and back-and-forth on the fly without any issues.Comparing the SDS1202X-E measurements with the re-licensed SDS804X HD using the same PP215 probe, all looks good.Mine came with 1.1.36 firmware and I updated to 1.1.38 for the latest UI changes.Even with the supplied PB470 70MHz probes it's possible to spot a 400MHz carrier using the FFT, I'm pretty happy with it.As above but with with interpolation off:

If so, how?I prefer Wifi to ethernet and the USB Wifi dongle is much smaller and easier to use than an ethernet to Wifi adapter.Thanks in advance.

content: QuoteThanks for your reply.I was wondering whether the limited speed of the 10/100 Mbps Ethernet on the TL-WR802N (effectively only about 10MBps) affects the interface performance and response when connected to the scope? In other words, would it be better to find a Ethernet to Wifi adapter which has a Gigabit Ethernet connection?

And the LAN port on the scope itself is only 10/100 Mbit/s anyway.

content: What a bear it is to get it off the usb port by hand. Indeed, there is no support fir the 725 or the 821 tp link.Hoping they will add support it one day. My Keysight scope doesn't support wifi or lan. So I'm relatively happy that it at least supports LAN, wifi would be a little more convenient.I agree with ebastler, the bottleneck is not the network for VNC. I played around with it a bit and even at low quality settings on the VNC client the update rate is the same.

Power cycle the instrument by pressing the power button.3. Immediately begin pressing the MATH button repeatedly at a rate of 2 to 3 times a second while the instrument boots up.4. If the instrument does not boot up properly, retry steps 2 through 4.HOWEVER, i don't see a need to do this, and i'm not even sure this is the kind of reset we're looking for. This may completely reset the license keys to factory default also. When i upgraded my SDS-812X HD to an SDS-822X HD (100MHz -> 200MHz) last night, i rebooted normally, used the default button, then ran a self calibration as the scope had been running for over 30 minutes. I have had no issues. My scope identifies as SDS822X HD, has the upgraded memory (and wave form capture rate i suppose?). Those reset instructions are for "In some extreme hardware errors, the oscilloscope may become unresponsive or “hang” during the boot sequence."https://siglentna.com/operating-tip/oscilloscope-hardware-reset/

content: Hi, has anyone noticed their SDS804X HD start "hanging" since upgrading to SDS824? Otherwise it seems to be working fine, but often enough it just hangs and I have to powercycle it...usually if I'm doing some stacked math stuff (like F1 = C1-C2, F2 is FFT of F1, that kind of thing)...I followed instructions, 70-100, load factory, then 100-200, load factory, then calibrate...maybe I should have power cycled before each bump up?I tried default and load factory settings etc. a few times...I haven't tried a Hardware Reset, do i need to backup all my saved settings for that, or is there any point trying it anyway.I wonder should I try just downgrade it back to 70...I don't 100% need 200 MHz really, (there was just one thing I wanted to look at).

content: I just joined the group today.Yesterday I ordered a Siglent SDS804X HD at Amazon, it should arrive in a weeks time.I read all the posts regarding the upgrade and also watched the YouTube video"TTE #28 - Siglent SDS804X HD - Upgrade To An SDS824XHD" several times.Also downloaded and installed on the desktop siglentkeygen.zip and siglent.py respectively.Either I missed in the video or it is not mentioned how and at what time in the upgrade process the scope would have to be connected to the computer (Windows 10 Pro, x-64 based PC). I can only speculate that a USB connection from the scope to the PC could be used.Since I don't want to wait with the upgrade until the warranty expires, I wonder if the scope would be rendered useless if the the upgrade failed. - Can the original condition (i.e. 804) be restored?Thanks in advance for any comments.

content: Thank you for the useful information.I guess I can use a USB-WiFi adapter or a RJ45 Ethernet cable from the scope to connect to my Router.The scope I ordered is already on the way to me. - I want to report on my findings, success or failure.
