- find a keypad (not urgent as currently I am using the rubber buttons and a screenshot of the keypad)

In the spirit of DIY, I deceived to make a 3D printed one myself. Not as nice as an original, but it works fine and is much easier to use than the rubber buttons. Attached the 3D design files should any-one be in a similar situation in the future.

_Wim_:
I have made some improvements to the 3D panel file to ensure the panel is more rigid, and to allow some additional travel for the buttons. The updated files are added in the post above.

Another update:
- I tested all functionality as it seems everything is working now  :-+
- As suggested in this blog (https://medium.com/@HP70K/70004a-display-screen-capture-43f7954d32b), I bought an Epiphan VGA2USB LR to allow me to easily take screenshots with all data (as the KE5FX 7470 plotter is missing some info). Attached an example when I was characterizing 2 Thorlabs  F240FC-980 collimators
- I routed the external input and outputs to the front for easily accessibility (see shelf picture)
- The OSA is now installed on my shelf with all the other optical test gear

This will be a very useful additional characterizing unknown optical parts bought on Ebay or when reverse engineering industrial optical analyzers.

If somebody would still come across the service manual, still interested to have a read through it. Also very interested in any software applications that work together with this OSA or functional that can be installed on the OSA via "measurement personalities".

Hello _wim_

Just received HP 71450B  -002 option White Light source module (separately).

I have OSA Agilent 86146B (not tested) and would like to test it with light source.

Additionally i have an Anritsu MT9810A optical test set with one power sensor module.

I would like to check the power of mine White Light source module.
And check Agilent 86146B with them.

Can you provide the spectrum of your built-in light source? I would like to compare with my.
