That 110MHz RF section is a peach.

THere is a matching tracking generator which also includes a Nixie tube display frequency counter. You can use it to pause and count the analyser at a chosen marker point so you can very accurately establish where things are.

I used such a setup for years doing filter development. It has the cleanliness to see well down filter skirts without reciprocally mixed pjase noise intervening.

The 1250MHz plug in uses a quite different tracking generator.
