The SDA-5500 is quite flexible with regard to sweep insertion, in that the
sweep level relative to the other carriers is not extremely critical. A key
principle to keep in mind is that the transmitter measures the levels of the
video and audio carriers simultaneously to the receiver. It also measures its
own injected sweep carrier. In order to do this, the sweep must be injected
prior to the tap which samples the system signal for the transmitter’s
measurements.
