SONY/TEKTRONIX AWG2020

[crj.guy]

Hello All,

I don't post a lot of questions asking for help here, generally because I find that the question has already been asked and answered by someone else a few years back.

But in this case..HELP!!!!!!

I haven't found what I need in the forum so here is my question.  I picked up an used Sony/Tektronix AWG2020, with the intention of using it in my poor mans E&E Lab however the input power is set for something other than what we use in the US of 120vac.  What I need is a wire diagram or some guidance on how to reconfigure the PSU to 120vac.

Can anybody help me?

Please?

Can you post a photo of the back?  According to the manual it appears to work on whatever voltage is provided and I didn't see any procedure for changing it.  The back panel may have something different to say.

The manual for 2021 (that is not that different) says it should go from 90-250V plus some exotic rack and military voltages and frequencies. So I think it should be OK as the standard US mains.

 Cheers,

A simple search with google gave me these links.

This one states to have a service manual, but you need a login to get to it.

This one is the service manual for the 2021. Not sure if it is the same, but see what you can get out of it.
