Byte #141 (8D H ); H ) - Anritsu Spectrum Master MS2711D Programming Manual

Set Spectrum Analyzer Resolution Bandwidth – Control Byte #141 (8Dh)
This command is new to the MS2711D. Use it instead of Control Byte #106 to access the new RBWs.
Description: Sets the resolution BW frequency for the Spectrum Analyzer.
Bytes to Follow: 4 bytes
1) Resolution Bandwidth (frequency in Hz) (Highest byte)
2) Resolution Bandwidth (frequency in Hz)
3) Resolution Bandwidth (frequency in Hz)
4) Resolution Bandwidth (frequency in Hz) (Lowest byte)
Spectrum Master Returns: 1 byte
1) 255 (FFh) Operation Complete Byte
224 (E0h) Parameter Error: Invalid RBW
238 (EEh) Time Out Error
Set Spectrum Analyzer Video Bandwidth – Control Byte #142 (8Eh)
This command is new to the MS2711D. Use it instead of Control Byte #107 to access the new VBWs.
Description: Sets the video BW frequency for the Spectrum Analyzer.
Bytes to Follow: 4 bytes
1) Video Bandwidth (frequency in Hz) (Highest byte)
2) Video Bandwidth (frequency in Hz)
3) Video Bandwidth (frequency in Hz)
4) Video Bandwidth (frequency in Hz) (Lowest byte)
Spectrum Master Returns: 1 byte
1) 255 (FFh) Operation Complete Byte
224 (E0h) Parameter Error: Invalid VBW
238 (EEh) Time Out Error
Set Spectrum Analyzer Attenuation – Control Byte #143 (8Fh)
This command is new to the MS2711D. Use it instead of Control Byte #111 to access the new attenuations.
Description: Sets the attenuation of the Spectrum Analyzer. Send a value of 255 (FFh) to enable dynamic
attenuation.
Automatic control couples the attenuation to the reference level. Note that setting the attenuation using this
command automatically sets the attenuation coupling to "MANUAL", thereby allowing it to be defined
independently of the reference level.
Bytes to Follow: 1 byte
1) Attenuation (0 – 51)
Spectrum Master Returns: 1 byte
1) 255 (FFh) Operation Complete Byte
