4.3 Conducted RF Measurement
4.3.1 Test Environment
Test instrument
R&S CMU200, R&S CMW500, Agilent E5515C
Power supply
Keithley 2303, Agilent 66319
RF cable for testing
L08-C014-350 of DRAKA COMTEQ or Rosenberger
Cable length: 29 cm

The compensation for different frequency bands relates to the cable and the test
environment.

The instrument compensation needs to be set according to the actual cable conditions.
4.3.2 Test Standards
Huawei modules meet 3GPP test standards. Each module passes strict tests at the
factory and thus the quality of the modules is guaranteed.
4.4 Conducted Rx Sensitivity and Tx Power
4.4.1 Conducted Receive Sensitivity
The conducted receive sensitivity is a key parameter that indicates the receiver
performance of ME909u-521 module.
Table 4-2 shows the typical Rx sensitivity values of ME909u-521.
