(

).Definition: This test evaluates how well the mobile station demodulates the Forward Traffic Channel in the presence of noise (simulated by AWGN). The performance of the demodulation of Forward Traffic Channel in an AWGN (no fading or multipath) environment is determined by the frame error rate (FER).
The following test procedure assumes that the mobile station supports Band Class 1 (US PCS) and only demonstrates the Test 1. You should change the settings as specified for other tests. Unless otherwise stated, leave all parameter settings to the defaults.

Close Measurement
(

).Definition: The RF sensitivity of the mobile station receiver is the minimum received power, measured at the mobile station antenna connector, at which the frame error rate (FER) does not exceed a specified value. The receiver dynamic range is the input power range at the mobile station antenna connector over which the FER does not exceed a specific value.
The following test procedure assumes that the mobile station supports Band Class 1 (US PCS). All settings for the Receiver Sensitivity test and the Dynamic Range test could be the same, except the cell power (Î or ) settings as shown below. Unless otherwise stated, leave all parameter settings to the defaults.
