And if the signaling connection is not established, sending an AT instruction through the serial port to restart. And restarting the test channel. And then, judging whether the module to be tested is reconnected with the comprehensive tester. And if the reconnection fails, reading the bandwidth power of the whole unit of the comprehensive tester, analyzing and judging the standard according to each frequency band and bandwidth, and judging the result. And if the reconnection is successful, setting the maximum power level of the comprehensive tester according to the bandwidth of the module to be tested.
And then, analyzing the unit power according to the bandwidth, setting the unit power of the comprehensive tester according to the unit power, and updating the unit power of the comprehensive tester by a preset step value. And updating the unit power of the comprehensive tester by using the preset step value, specifically, adding the preset step value to the unit power of the comprehensive tester, and setting the comprehensive tester by using the obtained result as the new unit power of the comprehensive tester. The number of sub-frames of the comprehensive tester will be set. Reading a BLER ACK (Block error Rate response) value, judging whether the BLER ACK value is larger than a lowest limit value or not, if the BLER ACK value is larger than the lowest limit value, analyzing the unit power again according to the bandwidth, setting the unit power of the comprehensive tester according to the unit power, and updating the unit power of the comprehensive tester according to a preset step value. And setting the number of the sub-frames of the comprehensive tester. Until the BLER ACK value is less than or equal to the minimum limit value.
And then, updating the unit power of the comprehensive tester according to a preset backspacing value. Specifically, the preset stepping value is subtracted from the unit power of the comprehensive measuring instrument, and then the obtained result is used as the new unit power of the comprehensive measuring instrument to set the comprehensive measuring instrument. The BLER ACK value is then read. Judging whether a BLER ACK value is 0 or not and the comprehensive tester is disconnected, if not, reading the whole unit bandwidth power of the comprehensive tester, and analyzing and judging a standard according to each frequency band and bandwidth to judge a result; if the judgment result is yes, analyzing the highest registered power, and setting the unit power of the integrated tester along with the highest registered power.
And then, sending an AT instruction through the serial port to restart. The test channel controls the restart key to restart. And judging whether the module to be tested is reconnected with the comprehensive tester. And if the reconnection fails, reading the bandwidth power of the whole unit of the comprehensive tester, analyzing and judging the standard according to each frequency band and bandwidth, and judging the result. And if the reconnection is successful, reading the full-unit bandwidth power of the comprehensive tester, and then judging whether the full-unit bandwidth power is 85dBm or not. And if the total unit bandwidth power is larger than 85dBm, reading the total unit bandwidth power of the comprehensive tester, and judging the result according to the analysis judgment standard of each frequency band and bandwidth. And if the power of the whole unit bandwidth is not more than 85dBm, reading the BLER ACK value of the comprehensive tester, and judging whether the BLER ACK value is less than the lowest limit value. And if the BLER ACK value is smaller than the lowest limit value, returning to the step of updating the unit power of the integrated tester according to the preset back-off value and executing the steps again in sequence. And if the BLERACK value is not less than the lowest limit value, reading the bandwidth power of the whole unit of the comprehensive tester, and judging the result according to the analysis and judgment standards of each frequency band and bandwidth.
And reading the bandwidth power of the whole unit of the comprehensive tester, analyzing and judging the standard according to each frequency band and bandwidth, displaying the setting of the comprehensive tester after judging the result, and displaying the measurement result.
And then, judging whether the measurement of each parameter is finished, if not, returning to the step of setting the line loss of the comprehensive tester, and carrying out the next round of measurement. And if the measurement is finished, disconnecting the module to be measured from the comprehensive measuring instrument. And finishing the measurement.
The WCDMA system measures the minimum signal level required to be input by the input end of the module to be tested under the condition of meeting the performance condition of not more than 5% of bit error rate on the basis of setting or switching each frequency band and channel at the maximum power level.
