QPSK EVM Measurement
Meas Setup
Limits
Accesses a menu that enables you to change the RMS EVM and Frequency Error limits settings.
RMS EVM
Sets the limit for the RMS EVM measurement. This value is used to judge whether the measurement
passes or fails the RMS EVM limit.
Freq Error
Sets the limit, in Hz, for the frequency error measurement. This value is used to judge whether the
measurement passes or fails the Frequency Error limit.

Mode WCDMA, C2K, 1xEVDO
Notes Sets the limits of RMS EVM which is used to judge the result of RMS EVM
passes or fails.
If a measured RMS EVM value is not larger than the limit value, the result is
PASS.
Otherwise, the result is FAIL.
You must be in the W-CDMA mode to use this command. Use
INSTrument:SELect to set the mode.
Preset WCDMA: 17.5
C2K: 100.0
