TDS 2002 psu noise

Hi all,

I have a Tektronix TDS 2002, and it has a great issue: it is noisy.

Its psu (switched-mode PSU) is very noisy, and radiates a 44 kHz signal
that contaminates DUT (dispositive under test).

I hope that Tektronix fixes this nasty problem.

regards,

luis.

Jim,


Yes, i do.

I went to Livingstone technical service, and they told me that is an
issue that ALL TDA2002 suffer, and they don't fixes that. My scope is
under warranty and Livingstone don't repair it.

Livingstone technical service was capable of found the same failure I
saw, follwing my instructions on how to measure and seeing it, but they
don't repair it because the same failure was saw in all scopes TDS2000
series they measured in their workshop.

amazing.

Then you need to contact TEKTRONIX directly.
Not a subsidiary,but the US factory.
