You are right. Thanks. I miss these resistors. I add it and it pass calibration again.

I don't think so. It looks like user calibration stops at first detected error. I also replaced components on frontends. I don't change  U40, U35 and U401. Below is photo of my hack. Resistors without making code are 16.2ohm.
Can you indicate which components did you change in the front end section?

I made hack using yours tutorial - photos attached to quoted post :P I left on board decoupling capacitors and ferite beads from removed amplifier.


EDUX front end mod to DSOX partial results.

I did the following mod to see if I can get 200MHz modding the front end on the EDUX to mimic the DSOX front end.

I worked on CH2 and the result is partial because I was not able to replace the LMH6550 to LMH6552 because it requires a package change from VSSOP to WSON.  The PCB has the footprint for both package types.

First picture shows the table of Vpp, Vmax and VRMS measurements of the different stages of the mod compared to the micsig TO1104 (just as validation of values).
The EDUX with just the resistor swap to make it think it is a DSOX: you get 70MHz, as is indicated on the utility/service/about this scope screen.
The EDUX with the resistor swap + the software hack (infiniiVisionLauncher.exe from /Secure): you get 120MHz, but utility/service/about this scope screen shows 200MHz.
The EDUX with the resistor swap + the software hack + the partial front end mod: you get less than 50MHz, as the front end mod removes the additional OPAMP that was added to the EDUX in the front end, and as it does not have the LMH6552 yet, it cannot get to 200MHz.

Second picture shows the hardware mod of the front end.  The hardware mod is partial because I am waiting for the solder paste to arrive to be able to solder the WSON Package

Third picture is the original DSOX (From Dave's Teardown)

Can some one tell me working values to ID 23 I got my edux go to 70MHz 2GSa SGM etc but I cant get signal at all
I had 12k on top and 33k on bottom on left side set when connector is up of them so it should get 0.91V
EDIT: that were wrong but bith 15k and 15k I should get ID 24 and no signbal at all also trtied 12k and 8k but no signal either it was  0.98V


Thanks a lot I ll try those also it does put me think if I did actually change wrong resistor set since I didnt find pic what would say which one is ID0 and which one is ID1 but when I did look those values
maybe my 12k vas actually 121k so i did change wrong id bit.

Yes that was the fault it works at 70MHz 2Gsa now thanks sadly its still edux so no CAN/LIN trial

I have almost complete schematic of main PCB. I don't found more hardware differences. I add missing trigger and generator components and it is work. I change resistor divider on main board to have ID 24. I don't change resistor dividers on BLT board, so I have DSOX1002G with 70MHz bandwith. Scope passing user calibration.

Code: [Select]
**** External Trigger Level ****

/5 Trig 2 B1 = 3492.000, B0 = 28593.000
**** CAL PASSED **** Time: 2 seconds


I'm going to make some test with wave gen, because I don't know the right values of capacitors and inductors.
Do you mind posting the full calibration output?  My unit is failing user calibration but at a different point during the test as before.  Before it was failing during External Trigger Level calibration.

Update Cal Failed Header

What is the point of updating the Cal Failed Header so every time the scope boots it shows uncalibrated warning message?  Technically the scope is not uncalibrated, it is calibrated to the latest good known values recalled from Usercal8.dat.

To remind you that something isn't 100%.

Without a noticeable warning, users may forget that the unit has an "issue".  It's easily ignorable after boot up - but you really don't want to be allowed to forget about it.

Besides, what if there was a real calibration issue - not related to a hack?

My scope has PCB REV A004

I have REV A005 which is related with BLT rev 003 and BLT_MODULE_CONFIG_0, 1.068v, ID3.
REV A004 is related with BLT rev 002 and BLT_MODULE_CONFIG_0, 0.687v, ID2.
Firmware looks the same in both cases. Maybe here is problem with calibration. I don't notices differences in hardware between A004 and A005. In BLT PCB I noticed one difference - bias resistors for memory. I set my scope to ID2 on BLT_MODULE_CONFIG_0 and it works. I noticed difference in device load time. On ID3 it is 0ms, on ID2 it is 1ms. However I can't handle the responsibility, when something goes wrong. I forgot to check user calibration on this setting. Here are resistors for BLT_MODULE_CONFIG_0.

Other option is that I rework all integrated circuits on main board while reverse engineering Maybe I broke something.

I wrongly assumed that user calibration was failing at the same point as before (External Trigger Level).  It advances and fails trying to finish some CH1 calibration before switching to CH2.  And I am having the same failure in both ID 24 (DSOX) and ID 22 (original EDUX) modes, so I am suspecting it must be some modification to the frontend I did.

I see something wrong with your startup.  It is giving "BLT Module Config 03 - UNKNOWN" error and the sample rate is 0GSa/s.

On my scope, I don't get the UNKNOWN error (as my BLT Module Config is 02) and the sample rate is 5GSa/s.

Did your BLT module came originally set to Config 03?

Yes, Original value was 03. I played with resistor dividers and BLT configurations above 02 as marked as unknown. It is probably information about BLT PCB revision. I have no idea what is problem with your scope now. Did you check solder points on connectors between main and BLT board? It's easy to broke it while removing BLT PCB. I totally broke solder points under 2 connectors while first BLT board removing, but after resoldering it works well. Please also check outside 47ohm resistors between LMH6552 and LC low pass filter in frontends. Here are differential signal split points to ADC and to U401.

I don't change these components.
Have you applied the FRA patch released by Keysight?

No. I haven't.

I think the FRA patch released by Keysight breaks the copyright message after the spash screen.  Where it used to say "Keysight Technologies..." it says "ght Technologies..."  after the patch is installed. 

Can anyone with the FRA patch installed verify?

Maybe the user calibration on my scope has to do with a triggering problem.  I realized it is not triggering correctly on rising edge.  I need to set the trigger level about 10% of the lower bottom of the signal and above to start triggering.  Falling edge triggers correctly.  I suspect it is the LOW PASS FILTER capacitor and inductor values that I tried to match to a 2000X, but I may be completely wrong...

All scopes have some hysteresis on trigger. Problem is related with CH1, CH2 or both? I check it on my scope. Rising edge need to little (about 10%) over bottom and falling edge trigger little under top of signal. I will try to install FRA patch, but before it I want to finish LAN adapter. Telnet can be helpful if something goes wrong. Do you have other Keysight scope like 2000x or something?

The trigger "issue" I have is with both CH1 and CH2.  But based on your description, it is within normal range.  I have an MSOX3024A.

I think I am getting close to the problem.  I noticed the signal is unbalanced.  I am feeding a square wave from the signal generator, 1Vpp, 1KHz, offset 0V.  I am seeing -531mV to +482mV on CH1, -523mV to +509mV on CH2.  I put back the original components in the LPF outside the differential amplifier, but there is no change in the signal levels.  I suspect this issue is related to the user calibration problem.

I will measure the differential outputs and post some pictures.

Did you replace the LMH6550 on the EDUX for the LMH6552?

Yes, I'm using LMH6552. After replace components I had problem with offset, but it's gone after user calibration, except 500uV/div. This setting is very noisy and with small offset. Try also measure voltages on differential out to VCM/ADC ref voltage (LMH6552 pin 2).
