5-21. Modulation Confirmation

BOARD Pulse
SPEC. 60 ± 5% at 5MHz
CAM OUT (75 W terminated)
TEST
ADJUST VR2 (CLMP PH) (Pulse)
CHART Immega Chart
M.EQ Waveform Monitor, EVR
1. Press the [F2] and [3] keys to set the EVR to
[1E][35][00].
2. Open the iris until white level is 80%.
3. Execute AWB function in the A ch.
4. Open the iris F5.6 – F4.
5. Confirm that the level At 5MHz is within
specification.
6. If not, fine-adjust the VR2. When VR2 is adjusted,
open the iris until white level is 80% and execute
AWB function in the A ch.
7. Confirm that the level at 5MHz is within
specification. (60 ± 10% is accepted only when
VR2 is fully-turned.)
8. When VR2 is adjusted, repeat from Modulation
Adjustment.
9. Finally, set the EVR to [1E][3A][00].
