Tektronix 11403 probe setup
« on: May 26, 2018, 12:32:15 am »
I recently acquired a Tektronix 11403 scope.  Due to lack of my experience with something this advanced, I'm having some issues.  I  hope someone can help me out.  I only have regular TEK probes without any intelligence and third party probes.

1)  Figured out that test signal output is usually disabled.  I have to be in certain mode to enable them.  One of them is deskew in probes menu.
2)  I go into deskew menu and run the process.  It always end with red banner that reads: "Probe cal complete.  Deskew FAILED.  Perform probe compensation procedure". 

I'm thinking this is so because it's a third party probe.  I think the intelligent probe that typically comes with this scope will have some intelligence feature to automate this.  Is it right that this is an expected behavior with normal probes?  Manual does not explain this very well and it only talks about using TEK probes.

Deskew is for adjusting/nulling the propagation delays between 2 probes so won't complete with a single probe.

They don't look to have anything but plain BNC's so any probe should work but I could be wrong.  :-//

Probe connector IS a BNC but it has terminals/ports/PCB are around it.  It encircles the BNC and has 4 individual connections.


I saw some video clip about doing this with 2 probes.  But TEK manual only talks about single probe.  I think what it is saying is doing this relative to the test signal.  It's all new to me.

I tried tek P6137 (400MHZ) and one cheap 60Mhz probe(black probe) on my Tek 11403A,both passed the probe (and deskew) calibration.

Thank you.  Then there is something going on with my scope then.  I will get with my cal lab folks and see what they can do for me.  Thank you for taking your time to do this and post pictures.

By the way, HOW did you take such a nice, clear and crisp picture of a display?  Mine has a CRT and I could never do it like that with mine.

What you need is a screen capture software of Tek 11000 series scope(for 11801x/11402x/11403x/csa803x/DSA602x,RS232 interface) and a RS232 cable( 9 pins to 25 pins).

I can't use this Tek Screen Snap screen capture software because my PC OS is WinXP thus I wrote my own screen capture software,but it can only run under WinXP (or earlier OS) and it's not completed yet.
