Title: Tektronix 754D knob/button panel interchange
Post by: tektech on March 09, 2023, 08:25:52 pm
I need a button/knob panel for a 754D scope. The panels from other models and generations look visibly identical. Anyone know
if all these other model's can be swapped into a 754D?

Welcome to the forum.

Sphere might have some:

Or there might even be a 3D printed model here:

So anyone know if all the similar models button panel will interchange?

All TDS500/600/700/800 series scopes use the same knobs. They are freely swappable.

What knob do you need? I may have a spare.

I think it's the panel itself he's asking the question about, rather than the knobs or buttons

Ah, well, yes. I should read more closely... :D

The front panels are interchangeable, mostly.

The main difference is the prescence or absence of the purple DPO button adjacent to the large knob.
A TDS754D has the DPO function so you will want a front panel that also has this function too. I believe it makes no real difference if it comes from a different model or revision.

My offer still stands though, let me know what you need exactly and I'll see what I have (if I don't have a complete panel, I might have the parts to repair yours)

Hey thanks for the offer TERRA, I found a complete panel from a 540B and it seems to work just fine on the 754D for anyone looking in the future.

Thanks for all the replies!

Sounds like it would be missing the DPO function if your scope is a D series though.

I did not try the button but I thought the InstaVu was what became DPO in the later models?
