3-3-14. Burst Adjustment
Rank:
B
Equipment:
Vectorscope (INT REF mode)
To be extended:
VA-156 board
Preparation
• BARS button/MSU-700 → "ON"
• S1361 (I/V ON/OFF)/VA-156 board → "ON"
• S1362 (Q/U ON/OFF)/VA-156 board → "OFF"
Test point:
VBS 1 OUT connector/CCU rear panel
Adjustment Procedure
1. Overlap the burst component to B-Y axis with PHASE
control on the vectorscope.
2. Adjust the burst level properly with 1RV1303 (BF
GAIN)/VA-156 board.
3. Confirm that the burst level at VIDEO OUT is 40 ±2
IRE(for PAL:300 ±10 mV) using the waveform
monitor.
4. Overlap both tips of the I (V) signal component to I
(V) axis with 1RV1304 (BF PHASE)/VA-156 board.
