QPSK EVM
This section provides information related to the TD-SCDMA QPSK EVM measurement from within the
List Sequencer. This measurement is available only if you have the TD-SCDMA measurement
application licensed on the test set.
In sequence analyzer mode only (not in TD-SCDMA mode), QPSK EVM results can be collected for
TD-SCDMA. However, measurement setup commands are not available in this case. The measurement
is available only with the following default settings:
• RRC Filter is ON, Filter Alpha is 0.22
• Chip rate is 1.28MHz
• EVM Result I/Q Offset is Standard
• Meas Interval is 864 chips
• Spectrum Inversion is Normal
• Frequency Error limit is 100 Hz
• RMS EVM limit is 17.5
QPSK EVM measurement SCPI commands
Measurement setup commands for QPSK EVM are not available in the case of TD-SCDMA. In this
case, measurement results are collected using the default setup described above..
