Adjust the position of terminal in control darkroom to specify on channel for i-th in test frequency range with being polarized to the first module
The position of optimum sensitivity and polarization, control base station emulator arranges the working frequency points of the first module for treating frequency measurement
The strong jamming frequency to be measured that section is specified on channel for j-th, the descending power of the first module is test frequency range i-th
The interval descending power of the individual appointment corresponding channel of channel, wherein, i ∈ N, N are that described test frequency range is specified
The number of channel, j ∈ M, M are the number that described frequency range to be measured specifies channel；
Accordingly, described base station emulator, specifically for opening the second module in j-th appointment of frequency range to be measured
Communication connection on channel, tests the bit error rate on the corresponding channel of strong jamming frequency to be measured for first module,
One corresponding channel of strong jamming frequency to be measured and frequency range to be measured are specified for j-th channel record is a channel
Combination, and record the corresponding bit error rate；From 1, i is got N, and j gets M from 1, obtains all channel group
Close and the bit error rate, the bit error rate of relatively more each channel combination, obtain the worst channel combination of the bit error rate.
