Hi,

i am owning an Tektronix 2467B. Maybe someone can give me some advice,
please.
The 2467B shows following message:
TEST 04 FAIL 13 (3453)
I have got the complete service manual, but it says something like
"Option Error" ???
(The scope includes Option 10 and 11.)

If i delete the error message by pressing the A/B tigger button, the
device works, but
it has a awful DC-Offset on all channels (which varies with the V/div-
selection).

Best regards from Berlin

Harald

Did you try running a DC balance? (IIRC,hold down both AC/DC/GND buttons
until the DCBAL procedure starts)

IIRC,"test 04" failures involve NVRAM memory retention.(all your cal
constants)

You may have to replace the NVRAM and recal the entire instrument.

Or you have bad preamp hybrids.

Hi Jim,

thank you very much. After running the Dc-balance the offset is ok !
...but the error message is still the same.
I forgot to say, that after deleting the error message,
there are a lot of question marks on the display:
for example

50mV???5V????......

Is it possible to post a foto in this group ?
I would be very glad, to get some advices.
Sorry i was wrong it is an 2467 not 2467B.

Thanks

Hi,

i forgot to say that after runnig the DC-balance cal. the error message
changed to :

TEST 04 FAIL 03 (3453)

The following things are still up to date:

I'd say you have to perform a full recal,and if this occurs again,your
NVRAM IC is bad,needing replacement and another recal.

You should ask this in sci.electronics.repair. There's a fellow who posts
there who used to work for Tektronix. (sci.electronics.repair added)

Well, we also read here :)

Looks like a problem in the calibration constants, stored in the NVRAM
A "TEST 04 FAIL 13 " condition means according to my manauls a "bad
checksum in the NVRAM".

If the NVRAM is ok, than this error can be corrected by doing the
calibration procedure (all steps mentioned in the handbook) and storing
the constants in the last step into the NVRAM.

hth, greets from Stuttgart,

Nicht leider, sondern das ist von mir so gewünscht und beabsichtigt.

It is likely to be a run-down battery. The calibration constants are held in a CMOS RAM which needs battery voltage to hold the calibration constants.

Useful, but this goes back to 2007.
