14 QPSK EVM Measurement
Meas Setup
Key Path
Meas Setup
Mode
WCDMA, C2K, 1xEVDO
Remote Command
[:SENSe]:EVMQpsk:AVERage:TCONtrol EXPonential|REPeat
[:SENSe]:EVMQpsk:AVERage:TCONtrol?
Example
EVMQ:AVER:TCON REP
EVMQ:AVER:TCON?
Notes
Selects the type of termination control used for averaging. This determines the averaging action after
the specified number of frames (average count) is reached.
Exponential - Each successive data acquisition after the average count is reached, is exponentially
weighted and combined with the existing average.
Repeat - After reaching the average count, the averaging is reset and a new average is started.
Preset
REPeat
State Saved
Saved in instrument state.
