I just got FSH8 handheld 8GHz spectrum analyzer from auction with broken display lens. I took a risk with hope that this is only damage it got.
I had FSH3 before and it was smaller, lighter than FSH8. And there is a reason. FSH8 is completely different beast, different engineering approach.
FSH3 digital part was almost the same as Fluke 192 series oscilloscope.
Fortunately for me SA was in good functional condition and i did not dare to open RF shielding can. So there are only pictures of naked can no RF porn.

Repair was boring two week long negotiation registration and ordering parts from R&S. Probably no need to mention that parts from R&S are arm and leg :)
Also ordered aftermarket battery claiming 10,000mAh :)
Once parts were delivered it took couple of hours to finish the job.
Have to admin R&S accepts money from poor people like me, not snob like Keysight.

Not even a peak under the can? :D
I think it being a different beast is right on the money, the FSH series is actually a whole slew of major revisions to the product - instead of just renaming them like other R&S stuff, they kept FSH and just kept making new analyzers altogether. I believe the order is something like FSH3+6 is the earliest variant, then the updated ones are marked like FSH3.13 or otherwise to indicate options, then the next version was the FSH4/8 introduction, no longer making the 3s and 6s, then I believe there's one revision beyond yours with a higher res screen and a different front styling. Not sure why they haven't differentiated the part names more, but I suppose I can understand why they'd want to keep the H for their handheld analyzers.
Does that mean the screen is damaged, or just the protective cover?

just EMI shielding lens. I was lucky this time.

Looks like you bought multiple lenses - R&S claims they don’t carry these anymore. Would you have one for sale?
