Figure 2-5: Pilot/SCA Phasing Scope Trace
To minimize the amount of peak level that the RDS subcarrier adds to the composite
baseband, your Optimod’s RDS generator is locked in quadrature with respect to the
pilot tone, so Figure 2-5 is for reference only. If your transmission system is broad-
casting stereo correctly, it will also correctly pass the phasing built into your Opti-
mod’s SCA generator.
