RF IN/OUT Loss Correction
Actual Input/Output Level and Correction
1 Actual Output Level and Correction in Automatic Test
(Except RF test), Manual Test and Signal Generator
The output signal of the tester is corrected for cable loss,
coupling loss, etc. by properly setting the parameters
described below
The 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 Signal Generator mode is
calculated by the following equation.
OutputLevel = BsLevel + LossRfOut
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 for cable loss, coupling loss, etc. by properly
setting the parameters described below.
The measurement results of RF test in the Manual Test
mode and the TX Analyzer mode are corrected by the
following equation.
Where:
OutputLevel The actual output level at the RF IN/OUT
connector.
BsLevel The setting value at the "BS Level" field
on the [Configuration: Test Condition]
screen or the "Amplitude" field on the
[Signal Generator] screen.
LossRfOut The setting value at the "LOSS/RF Out"
field on the [Configuration] screen.
NOTE
OutputLevel must not exceed –20.0dBm. Therefore,
care must be taken to ensure that the setting of the
BsLevel and the LossRfOut does not cause
the OutputLevel to exceed the –20.0 dBm
limit.
