microwave MOD Frequency & DIP Frequency

I have setup one Microwave testbench as shown in figure.

Modulation (MOD) frequency knob of Microwave source is been set at
mid position. Now the Frequency Meter reads a DIP Frequency of 9.34 GHz.

From Reflex Klystron MODE Study it is evident that- for all maximum
output power points, the DIP value will be same irrespective of repeller voltage.

SO,
Can I change DIP Frequency by

1. Changing MOD Frequency Knob position ?
2. Replacing Klystron Supply with Gunn Supply ?
What are the factors that decides DIP Vlaue ?
What is the difference between MOD & DIP Frequencies ?

Hello,

You have found a schematic.
Do you also have some text with that schematic parts?

As for as I know the MOD is used to modulate the microwave signal to make the dip visible.
Without modulation there will be no dip.
