Where I come from, we call that a comb generator, not a signal generator...
Ya gotta know the limitations of your test equipment. I recently went
several rounds via telephone with a friend of mine who was trying to
troubleshoot an apparent desense problem on the bench involving a Mastr II
and a 6-cavity DB Products duplexer that I had tuned up for him on the VNA.
Long story short, it turned out that when he was doing the desense test
using his service monitor (R2600?) as the dummy load and signal source
simultaneously that the sig gen would go spurious and result in apparent
desense. When he finally did a lossy tee test using an external dummy load,
no desense, and likewise when hooked up to the antenna at the site, no
desense.
