Your post reminds me of Heathkit. Heathkit sold many great transceivers in kit form and they never asked the buyer to be equipped with test equipment. I remember when I put my HW-101 together. The only instrument I was asked to use was the little panel meter that came as a part of the radio with the kit. When fully ready the meter becomes the S-meter or Ic meter. Signal source were internal oscillators. I remember the entire process of alignment was done using these two devices. In the end I had a great transceiver.
Yes, certainly you can use your oscilloscope as a frequency meter, or to measure all kinds of parameters including frequency, Vp, Vrms, etc. I have used my purely analog scope. Sure, I had to calculate the frequency using the rough estimate of the 'period' of a cycle or the waveform. I knew the result will have an error to the level of 10 or 20%. Who cares as long as I was able to get my work done? A decent scope will do everything that you listed. You may need a calculator for calculating.
As I said you surely can use a good RF/AF generator but they are not essential to align a transceiver. We hams are good at putting to use our limited resources.
Good luck

Subject: [Amateur-repairs] substitute test equipment
I am starting to go through the alignment on one of my radios and don't have every piece of test equipment listed in the service manual.
So, I wanted to see if I could use the following substitutions.
For the frequency counter & RF voltmeter, couldn't I just use my oscilloscope? I have access to a scope that can internally measure all kinds of parameters including frequency, Vp, Vrms, etc. Any problem with doing that?
Audio signal generator: I have both a program on my computer and an app on my phone that will generate audio tones at adjustable levels. Any problem with that instead of using a dedicated audio generator?
I still need to get my RF signal generator up and running. I have an old wavetek that is a little persnickety...
Thanks,
Albert
