Performance Verification Test Procedure
5.2.1
Level Calibration
1.
Description
1.
Measure level calibration measurement accuracy for 3GPP system.
2.
Firstly measure a signal generator output signal level for several testing points by
using RF power meter and RF power sensor as reference data.
3.
Secondary, measure the signal generator output signal by Tx power measurement
function of R3267 Series.
4.
Compare the both measurement result of RF power meter and R3267 Series.
5.
Record the difference as level calibration measurement accuracy.
6.
Repeat measurement for input attenuator setting 10 dB through 50 dB.
R3267 Series is phase locked with the signal generator.
