21.20 SG-2000 Performance Measurements
The following is a diagram of how to set up appropriate test equipment to
ascertain the performance of the SG-2000 transceiver.
It is important that the equipment be set up as noted in the diagram on the
following page and that the technician or engineer performing the measurements
insures that all test equipment is in good working order and has been properly
calibrated prior to performing measures.
The SG-2000 is completely aligned and tested at the SGC factory prior to
shipment. No further adjustment of the radio should be necessary. It is
recommended that the operating frequency of the radio be certified by a
qualified technician on an annual basis in conjunction with a good preventative
maintenance program as noted earlier in this manual.
