HP / Agilent 53131A / 53132A VFD to LED Display Conversion

[dimmog]

This is a drop-in replacement for the VFD display used in the HP / Agilent 53131A / 53132A / 53181A counters.
The new display is LED-based and requires no modifications to the counter.

Happy Holidays!

Interesting - Is there a link to the display?

The display module will be ready for sale soon.

Oh my. 

I replaced the VFD with a new one in my 53132A, but this has my attention... What sort of cost are we looking at?
Will it be open sourced?

I assume it is something like a 3D printed frame on top of SMD LED's with a 'shadow mask' overlay sticker or similar? Looks neat!

And presumably this same technique can be easily adapted to the 34401a as well with appropriate annunciators!
Certainly very interesting.

Thanks. We are open to price suggestions.

The same VFD is also used in the 58503 GPSDO.

Yes, it can be adapted, but there are currently plenty of affordable new VFDs available for the 34401A.

This is not a 3D-printed frame. It’s a high-quality, professionally made LED display.

The only difference from the original is the blue color instead of cyan.
