Measure V5 output amplitude. Set the chroma

frequency (CW) to 3.08MHz and measure V6

output amplitude.

CBE308 = 20Log (V6/V5)

Measure V7 output amplitude when the chroma

frequency (CW) is 3.28MHz and V8 output

amplitude when it (CW) is 3.88 MHz.

CBE = 20Log (V8/V7)

Set the chroma frequency (CW) to 4.08MHz and

measure V9 output amplitude.

CBE05 = 20Log (V9/V6)
