Configuration Parameters 67
Measurement The measurement (or calculation) performed to
produce the Band Value. See Data Parameters on
page 89.
•
Band Overall - The Band Value is the square root
of the sum of the squares (RSS) of the amplitude
values for the bins that make up the band. If the
band includes all of the spectrum bins then the
Band Value is equivalent to the digital or RSS
overall value.
•
Max Peak in Band - The Band Value is equal to
the maximum bin amplitude found within the band.
Options: Band Overall
Max Peak in Band
Minimum Frequency The spectrum bin with the least frequency to be
included in the band measurement. Options (XM Serial Configuration
Utility): Hz
CPM
Orders
Note: Order-based bands are
supported only when Spectrum
Option is set to "Conventional
Spectrum.'
Maximum Frequency The spectrum bin with the greatest frequency to be
included in the band measurement. Enter a value greater than or equal to
Minimum Frequency.
Note: This value must be less than or
equal to FMAX. For conventional
measurements, see page 65. For gSE
measurements, see page 70.
Frequency Units (EDS File only) Defines the units of the Minimum and Maximum
Frequency values. Options: Hz
Orders
Note: Order-based bands are
supported only when Spectrum
Option is set to "Conventional
Spectrum."

TIP
The Frequency ranges for each band may overlap. For
example, Band 1 Minimum Frequency is 500 Hz and
Maximum Frequency is 1500 Hz, and Band 2 Minimum
Frequency is 1000 Hz and Maximum Frequency is
3000 Hz.
