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 RF Level on the [Manual Test]
screen, Amplitude on the [Signal Generator] screen,
Amplitude on the [TX Analyzer] screen, Max TX
Power BS Level, Min TX Power BS Level, Measurement
BS Level, FER BS Level (when MC-1x Mode is
selected), PER BS Level1, PER BS Level2 , PER BS Level3
(when 1xEV-DO Mode is selected) on the
[Configuration: Test Sequence] screen.
LossRfOut = Setting value at the RF Out field on the
[Configuration: Test Condition (Loss)] screen.
There is a restriction that the OutputLevel cannot exceed
–18.0 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.
