Tektronix TDS7254B Signal Path Compensation fail issue and pass all Diagnostic

[snoopy_lei]

Hello everyone,

Would you help me to Close TDS7254B SPC fail issue or give me some suggestions? However thanks for your help in advance.

The TDS7254B can pass all Diagnostic as attach picture and only fail in SPC calibration,however I check the PowerPC board's debug info via few wires to connect PowerPC debug serial port,however the error info as below when run the SPC calibration instruction,

However I have restore the WINXP system with TEK TDS7KB RestoreCD and reinstall the Tekscope software,but the issue same as before,and "M866CompCalibrator 3c Failed" "M866CompCalibrator 4c failed" the info is very confusion,what is M866? It's Chip IC or software instruction? What is 3c and 4c? it's mean the 3rd channel and 4rd Channel?

After I warmed up all night, I ran SPC again and displayed the following message.the "CC_TRIGdcGain3c" constant have some change,but failed same as before,
As we know The DCGain characterized at factory cal and stored along with all other calibration constants in NVRAM,Perhaps it is because the error that has accumulated
over time has caused the current DCGain to exceed the allowable error range.How to adjust the DCgain to the allowable error range? Another possibility is that there is
a problem with the NVRAM data

Hi Snoopy!

Obviously you know a lot about the internals of these scopes. Maybe you can give me a hint, where to look for the problem with my defective CSA8000B?
In particular there are two things which could help:
1. Is there a way to read the data from the NVRAMs on PPC and ACQ-Board in order to write them back after replacement?
2. Mine gets stuck during startup of the scope app. PPC shows "P", i get "Kernel running at 10 ticks per slice", then some connection task is going on and somewhere there it gets stuck... Any ideas??

I'd greatly appreciate any help!!!

[charlyd]

Hi did you ever find the answer i have a csa7404B here with same error on all 4 channels.

[mikehank]

Hi guys,

The M866 the channel preamp.  Check for any output voltage on the input.  You don’t have a new SPC so there will  be some but not more than 5-6mv

[charlyd]

@mikehank :  M866 pre amp ....uuh what component are you pointing to i will add my log also to compare ;-)

[mikehank]

So your failure for spc is common.  Diags are will not pick up the M866 calibration failures.  What is happening is spc is applying a calibration signal to the preamp for various measurements and the signal is out of range(too small or too large) and fails.  Attached are a couple of pic's that may help.  Install a TNC-BNC to the input of a channel and measure for mV.  You should not see very much under 5-6 mv or so.  If you have more this is the source of the out of range M866 failure. 

[mikehank]

Here is another file

[charlyd]

Hi Mikehank, yes i have seen this picture but you think the problem is pre-amp related? ok but for all channels then?

does any body have  a picture of those pre-amp without the heatsink.  so the code on top of the chips.

ah i just saw you posted 2 messages (with xlsx)...thanks for your help and support...

[matthuszagh]

charlyd, did you ever figure this out? I'm seeing something similar.

[charlyd]

hi Matthus , no i parked the unit and went to the next one.

So, you have a similiar issue ?

btw somebody explain when 351 - Acquisition-->HFStep-->PhaseCal is displayed  in Diagnostic.

[charlyd]

hi is there any clearance on the M866 issue
M866CompCal failed  i now have a TDS7404B  with  ACQ Diags all pass. 
this 7404B unit also has a ch3 and ch4 error exact like the 7254B in first post.  it looks like it should be a component or circuit for two channels. So that there are two of the same circuits/components for each two channels and one of the two circuits is failing.

so i guess there must be a relation. It is a bit difficult to dive deeper because you need to measure on the back side of the ACQ board.  someone already experienced with let say extension cables or something? 

specially to jaywalling because of your experience
any m866 news?

i am willing to pay $200 to whom who can point me to the M866 Comp Cal failed solution. like in first post
