These commands provide test set specific settings for the Error Vector Magnitude (EVM) measurement.
Sets/queries whether or not averaging is performed on the EVM measurement.
The number of averages is set using [SENSe:]EVM:AVERage:COUNt[?].
This EVM command is applicable to all the WLAN radio standards which is set using [SENSe:]RADIo:STANdard[:SELect]:WLAN[?].
Setting Range: 0 | OFF | 1 | ON
Query Range: 0 | 1
*RST Setting: 0 | OFF
Test Set Requirements: N8300A Wireless Networking Test Set Version A.02 and above
Example:
EVM:AVERage ON
Turns averaging on for the EVM measurement.
Sets/queries the number of averages to be made for the EVM measurement.
Averaging can be switched on or off using [SENSe:]EVM:AVERage[:STATe][?].
