Methods and systems for testing a hydrocarbon well. The cord organizing sheath assembly includes a sheath having a pair of open ends, a pouch for receiving and holding socket ends of cords, and a tether line attached to the sheath for pulling the pouch through the sheath such that the cords are threaded through the sheath. Whenever a smaller output power is desired in response to reduction in the input signal to the amplifier, the load is further tuned, such that the dynamic or static RF load line has a slope that causes the power amplifier to essentially remain in saturation at the smaller output power.
