When Rx == Tx

TX 1 -> LMR-400-FR coax cable -> ATTEN (30 dB HIGH POWER) -> fem/fem type-N to SMA adapter -> 60" RF 32027 astrolab cable -> DIRECTIONAL COUPLER input port -> 24" RF 32027 astrolab cable -> 20 dB attenuation -> DELAY LINE -> 40 dB attenuation -> 24" RF 32027 astrolab cable -> DIRECTIONAL COUPLER couple port (6 dB) -> 60" RF 32027 astrolab cable -> fem/fem type-N to SMA adapter -> ATTEN (30 dB HIGH POWER) -> LMR-400-FR coax cable -> RX N

	Directional coupler is the same.

When Rx >= 2
TX 1 -> LMR-400-FR coax cable -> ATTEN (30 dB HIGH POWER) -> fem/fem type-N to SMA adapter -> 60" RF 32027 astrolab cable -> DIRECTIONAL COUPLER input port -> 24" RF 32027 astrolab cable -> 20 dB attenuation -> DELAY LINE -> 40 dB attenuation -> 24" RF 32027 astrolab cable -> fem/fem adapter -> 48" RF 32027 astrolab cable -> fem/fem type-N to SMA adapter -> LMR-400-FR coax cable -> RX N
