Signal Generator & Osciliscope

Yes but it takes some money. How are you connecting to the unit under test?

I have the scope and generator, i inject the the tone through antenna jack and i use the scope for test points only.
I'm for sure a beginner in the diagnostic department, but that is what I do and don't quite understand your problem...?
I have seen videos where techs use one bnc cable to operate there rfsignal generator and scope on one bnc cable
I use a vintage Heathkit antenna switch, with the dummy load, antenna and signal generator on it. The signal generator is protected by a sensor box that disconnects it if a radio accidentally gets keyed into it.
The counter is tapped off of a "TEE" on the coax switch input socket, where the radio feeds into it. I use an obsolete 80-MC mike plug with a flat washer soldered to the center pin on the other side of the TEE from the radio coax. It provides a coupling capacitor of about 1pf, or a little less to the center pin of that side of the TEE. This prevents the counter from being overloaded like it would with a direct connection. Only drawback is that you need around a Watt and a half to get a stable reading.
The 'scope has one channel connected to the demodulated output on the dummy load. I can only "see" what comes out of a radio on the dummy, but not the antenna. It's a Heathkit Cantenna, with the demodulator modified to display clean audio.
The second channel on the 'scope has a probe on it for the usual troubleshooting and alignment tasks.
Used to have Tek 465 scopes that provided a "Channel B output" jack on the rear. A jumper from this jack to the counter was incredibly handy, and allowed me to use the 'scope as a preamp for the counter. Besides, it was handy to know the frequency of an RF signal on the 'scope screen.
Turns out that this is not a commonly-found feature. Dern handy for radio troubleshooting, though.
