The 'Z' pattern is deliberate. Microwave ovens don't use a fixed frequency, which allows better surface penetration of the food.
Microwaves work by exciting water molecules, which release energy, heating the food. Keeping the frequency fixed here would block deeper penetration whilst the outer molecules sit at their resonant frequency.
Depending on the design, many use a saw (as seen here) or triangle offset to shift the frequency around. The 2nd oven seems to be more stable and better filtered.
the 3 pan of noise is radar a long range radar uses microwave radation thus the second noise radar on screen is visible for 1,209 miles for a 4 class destroyer the radation can still travel after it is no longer visiible
As soon as the microwave cycles on in the other side of the house, my WiFi connection goes out cold. About a week ago I was surfing with my PSP, and someone put a coffee in the microwave, the router froze and only the wired section worked. I had to go to THE VERY NEXT ROOM* and press the 'reset' button with a toothpick. A few days later I was listening to the 4Mhz band on my shortwave radio and the reception got worse.
*mind you, me and the router are at the end of the house without the MW oven.
It looks like the unknown interference is a harmonic of the microwave. Meaning it is just getting amplified and displaced some how. As you can see it follows the same pattern that the microwave does.
Sometimes the "z" designs that the microwave makes are a result of the food in the microwave spinning.
Because the second Z pattern higher in freq is occuring only when both the WiFi and the Microwave are on, I'd submit that it is more likely a result of "mixing" than a harmonic.
That Z pattern due to spinning is an interesting theory, but how would spinning food make the frequency change? Amplitude yes, freq I don't think so. Could be the design of certain microwaves to avoid persistent interference w/ consumer electronics...would interfere some of the time but not all = fewer complaints.

These Wi-Spy hardware don't come cheap. Is it really really worth it???
