If it's too awkward or expensive to fix, there is the amazing TinySA Basic and TinySA Ultra.
I did have an HP141T with four RF plug-ins. It died (a third time), so I got a 1.5 GHz Rigol with Tracking generator (works as signal generator if span= 0). I did recently get a TinySA Basic just to use as radio waterfall spectrum display (via buffer just in front of IF). It's actually pretty good to align and test from 100 kHz to GHz, but best at 1 MHz to 350 MHz. Signal Generator mode, but you need an external 30dB attenuater for radio alignment. Can't use Generator as a Tracking Generator without an external mixer and 433.92 MHz LO (which happens to be what the cheap 434 MHz gadgets use!).
There is a TinySA Groups.io and the designer answers questions not in the Wiki.
