Actual Input/Output Level and Correction
1 Actual Output Level and Correction in Automatic Test (Except RF
test), Manual Test, and Signal Generator
Output signal level of the Tester is corrected according to cable loss,
coupling loss, and etc. Some of parameters should be set properly.
Actual output level (for downlink signal) at the RF IN/OUT connector
in the Automatic Test mode (except RF test), the Manual Test mode
and the Signal Generator mode is calculated by the following equation.
Where,
OutputLevel = Actual output level at the RF IN/OUT connector.
BsLevel = Setting value at the BS Level, BER BS Level and BLER BS
Level field on the [Configuration: Test Condition] screen or
the Amplitude field on the [Signal Generator] screen.
LossRfOut = Setting value at the LOSS/RF Out field on the
[Configuration] screen.
There is a restriction that the OutputLevel cannot exceed –20.0 dBm,
so at each parameter, the BsLevel and the LossRfOut must be set to
meet this restriction.
2 Actual Input Signal Level and Correction in Automatic Test (Except
RF test), Manual Test, and TX Analyzer
Input signal level of the Tester (for uplink signal) is corrected
according to cable loss, coupling loss, and etc. Some of parameters
should be set properly.
The measurement results of RF test in the Manual Test mode and the
TX Analyzer mode are corrected by the following equation.
Where,
InputLevel = Corrected measured value of the Tester.
MsLevel = Input signal level of the mobile phone at the RF IN/OUT
connector.
OutputLevel BsLevel LossRFOut+=
