Embodiment 2
[0046] The present embodiment makes further supplements on the basis of embodiment 1, specifically as follows:
[0047] This embodiment provides a method of combining radio frequency internal and external correction. The method provided by this embodiment further includes:
[0048] (4) Combination of internal and external correction after replacing parts:
[0049](a1) When there is a problem with the radio frequency cable or radio frequency channel part, replace the radio frequency cable or radio frequency channel part that needs to be replaced into the radio frequency system, perform internal calibration, and obtain the amplitude value table of each frequency of each radio frequency channel after replacement, and record it as No. The second internal correction configuration file is stored in the system computer board for operation, and the second internal correction fitting curve of each radio frequency channel is obtained, such as Figure 7 shown;
[0050] (a2) Equilibrium...
