As shown in fig. 1. The formats of the command and response for querying the sampled values of the rf signal are shown in fig. 7 and 8, respectively. In the figure, the source and the destination of data are distinguished according to the source and the destination codes, when PC network management software sends a command to the network management board software, the source is 01H, the destination is 02H, and when the network management board software sends a command to the radio frequency service board program, the source is 02H, and the destination is 03H. The same principle applies to the transmission of response data.

2. When the power sampling table needs to be modified, the radio frequency service board does not need to be detached from the whole machine to update the program, and the structural tightness of the whole machine is not damaged;
3. when the power sampling table is measured on the radio frequency service board, the radio frequency service board does not need to be detached from the whole machine, the electromagnetic environment at the moment is the final working environment of the radio frequency service board, the measured power sampling table is more accurate, and the radio frequency signal detection calculated by the service board program is more true and accurate.
4. When the radio frequency optical transceiver equipment is installed on a test site and is in a working state, the optical transceiver is not allowed to be powered off to interrupt signal service, at the moment, a power sampling table can be updated online and remotely, and equipment maintenance is carried out in operation;
5. Because the power sampling table is separated from the program, all the radio frequency service boards use the unified program, thereby facilitating the archiving and mass downloading of the software. On the other hand, for the radio frequency service board with the consistent height of the power sampling table, the power sampling table can be measured once (or read out to be measured), and then the radio frequency service board is reused and used in batches, so that the efficiency is obviously improved.
6. In the batch production process, the whole machine assembly can be firstly carried out, then detection of all radio frequency business boards in the radio frequency optical terminal machine is carried out, the detection and the writing are carried out, the efficiency is improved, and the process is flexible.
