TEST_06 TX Peak Power Error
TEST_06 TX Peak Power Error
Description This test verifies that the mobile station transmits the proper power
level for its power control levels (TX Levels). The mobile’s transmitted
power is compared with the GSM 11.10 recommended, GSM 11.10 DCS
recommended, and PN 3389 recommended levels, and the amount of
error is displayed.
The TX default power control level parameter determines the
starting level for power measurements.
Measurements are made on decreasing power levels according to the TX
power level step for peak power parameter.
The sequence of power control levels is repeated for each channel
selected in the TX in-channel sweep test channel parameter.
Peak power is measured by averaging the transmitted carrier power
over the middle of the pulse (when the 147 useful bits are present).
