Appendices FIGURE 8-G – EXCITER BOARD ALIGNMENT PROCEDURE 1. Connection Connect the cables from RF unit to J1 (signal and power source), J3 (10.7 MHz) and J4 (10 MHz). Connect a modulation analyzer to J2 (output). 2. Alignment 2-1 VCO 2-1-1. Use a PLL data of the frequency that is actually used for data transmission. Turn power on. While monitoring TP1, adjust the core of the channel VCO for approximately 4V. 2-1-2. While monitoring TP2, adjust the modulation VCO for approximately 4V. 2-2 Modulation 2-2-1.
