I found a new online vectorizer that I like. The results are sometimes uneven but as with my other PDF to DXF tool it's a good enough starting place.

I also found recommendations for the online vectorizer 'VectorMagic' which seems nice but after it does the conversion it wants you to pay a monthly fee to download the result: https://vectormagic.com/
Here is the source for my starting image of the AWG, which is a Keysight 33521B: http://rfmw.em.keysight.com/spdhelpfiles/33500/webhelp/US/Content/__C_Quick%20Start/Quick%20Start.htm
That page for the AWG is interstingly an html-ification of the manual for the AWG, which can be found here: http://literature.cdn.keysight.com/litweb/pdf/33500-90901.pdf
The datasheet for the AWG, here, is nice but doesn't contain any line drawings of it: http://literature.cdn.keysight.com/litweb/pdf/5991-0692EN.pdf
