RX PORT CALIBRATION
The following will calibrate the ASM Rx levels read from an output port of the receive multicoupler.
For TTA / RX multicoupler systems, enter the system Reserve Gain in the “RX Subsystem Gain (Loss)” field. For non-TTA
systems, enter the net of the RX feedline loss and any multicoupler gain. Gain is entered as a positive number, loss as a
negative number.
The “RX Post Gain (Loss)” field is for any gain or loss in line with the ASM RX input which is not present in the path to the base
receiver(s). Click on the “Help” button shown for further explanations. The objective here is to ensure that the ASM is
displaying the receive level present at the input of any site receivers.
When a Receive Systems Module (RSM) is fitted to the ASM, the three receive signal paths (RxA, RxB and RxE) are configurable
in the Calibration – Rx Port page.
