InputLevel = MsLevel + LossRfIn
3 Actual Output Level and Correction for RF Test in
Automatic Test
The output signal level of the tester is corrected for cable
loss, coupling loss, etc. by properly setting the BsLevel,
LossRfOut and the AttOut parameters.
The actual output level (for downlink) at the RF IN/OUT
connector for RF test in the Automatic Test mode is
calculated using the following equation.
OutputLevel = BsLevel + LossRfOut + AttOut
Where:
InputLevel The corrected measured value of the
tester.
MsLevel The input signal level of the mobile phone
at the RF IN/OUT connector.
LossRfIn The setting value in the "LOSS/RF In" field
on the [Configuration] screen.
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.
LossRfOut The setting value at the "LOSS/RF Out"
field on the [Configuration] screen.
AttOut The setting value at the "ATT Out" field on
the [Configuration: Test Sequence] screen.
NOTE
There are 2 restrictions the must be observed when
setting the parameters:
1 The OutputLevel must not exceed –20.0 dBm.
Therefore, ensure that BsLevel, the LossRfOut
and AttOut are correctly set to meet this limit.
2 The sum of the LossRfOut and the AttOut
parameters must be set to be greater than or
equal to zero.
