During RF coil design and construction process characterization (bench testing) is a necessary step to ensure coil functionality and optimal performance. This lecture will explore and elaborate on critical functional and performance metrics of RF Coils. Topics discussed in detail include

• Coil Tuning.
• Coil Q and Q ratio.
• Q ratio and SNR.
  
• Impedance Matching.
• Coil coupling and Noise correlation.
• Preamplifier decoupling (Receive coils only).
• Interface electronics characterization (Quadrature hybrids, T/R switches).
• Characterizing RF Coil safety circuits (De-tuning circuits and Cable traps).
