I was recently told (by another ham) that I could ONLY tune up my 70cm duplexer cavities using something called a "tracking generator". Unfortunately I do not have one; and judging the prices I have seem for things with that name on the web, I doubt that I can easily budget to purchase one.
For some reason, I thought that my father used to tune up resonant cavities using a sweep generator, oscilloscope, and a frequency counter; but I don't recall the exact setup he used. I inherited his Wavetek (Model #1080, 1GHz) sweep generator, oscilloscope, and frequency counter. I also have access to an IFR-1100 service monitor, if I need it (i.e., can be borrowed from a friend). Can I tune up my 70cm duplexer cavities using the equipment I have? If so, could someone please indicate the test setup and procedure. Thank-you.
