These commands provide data processing functions for the Spectral Mask (SMAS) measurement.
Sets/queries whether or not the fast mask is used. Fast mask is a mode for spectral mask that decreases the time taken to perform the measurement by around 50%. If this command is set to ON a value of 108.2 kHz is used for the residual bandwidth setting when making the spectral mask measurement. This gives a much faster measurement but slightly less accurate.
Setting Range: 0 | OFF | 1 | ON
Query Range: 0 | 1
*RST Setting: O | OFF
Test Set Requirements: N8300A Wireless Networking Test Set Version A.02 and above
Example:
CALCulate:SMASk:FMASk ON
Sets the fast mask on for the Spectral Mask measurement.
Sets/queries the reference level for the Spectral Mask measurement. The reference level can be set manually using this command or automatically using CALCulate:SMASk:RLEVel:AUTO[?].
Setting Range: -999 to 100 dB
Query Range: -999 to 100 dB
Resolution: 0.00000001
*RST Setting: -999 dB
Test Set Requirements: N8300A Wireless Networking Test Set Version A.02 and above
Example:
CALCulate:SMASk:RLEVel -30
Sets the reference level to -30 dB for the Spectral Mask measurement.
Set/queries whether or not the reference level is set automatically for the Spectral Mask measurement. If this command is set to:
ON, the reference level used is the peak of the analyzed signal.
OFF, the reference level used is the manual level set using CALCulate:SMASk:RLEVel[?].
Setting Range: 0 | OFF | 1 | ON
Query Range: 0 | 1
*RST Setting: 1 | ON
Test Set Requirements: N8300A Wireless Networking Test Set Version A.02 and above
Example:
CALCulate:SMASk:RLEVel:AUTO ON
Sets the reference level to be the peak of the analyzed signal for the Spectral Mask measurement.
Set/queries the measurement span size used for the Spectral Mask measurement.
SPAN22: 22 MHz
SPAN44: 44 MHz
SPAN66: 66 MHz
SPAN120: 120 MHz (Note that this measurement span should only be used with 40 MHz bandwidth signals.)
Setting Range: SPAN22 | SPAN44 | SPAN66 | SPAN120
Query Range: SPAN22 | SPAN44 | SPAN66 | SPAN120
*RST Setting: SPAN22
Test Set Requirements: N8300A Wireless Networking Test Set Version A.02 and above
Example:
CALCulate:SMASk:SPAN SPAN66
Sets the measurement span to 66 MHz for the Spectral Mask measurement.
Set/queries the measurement windowing type for the Spectral Mask measurement.
Setting Range: GAUSsian | FLATtop | HANNing | UNIForm
Query Range: GAUS | FLAT | HANN | UNIF
*RST Setting: GAUSsian
Test Set Requirements: N8300A Wireless Networking Test Set Version A.02 and above
Example:
CALCulate:SMASk:WTYPe HANNing
Sets the windowing type to hanning for the Spectral Mask measurement.
