4) Narrow down the pattern window from the entire spectrum to just the frequencies that
are relevant to the device. To do this, click the left edge of the desired range and drag to
the right edge of the range.
5) Replace New Signature with a custom name for the signature.
6) You may also assign the signature to a group using Group Name. All signatures assigned
to the same group will show up as children of that group in the Device Signature List that
is part of the Custom Device Classification Manager.
Note: Both Pattern Start and Stop fields will be auto-filled with the frequency range.
7) Select whether to use the Current or Max data line for the Spectrum Data Type. This may
depend on which is best based on which one provides a consistent, distinct pattern. Both
data sources may be selected in order to have the system detect the defined pattern on
either of the data sources. For example, hopping or short-burst devices should use the
max setting for the Spectrum Data Type instead of the current, as the Max data gives a
more distinct pattern in this situation.
8) The Category drop-down enables you to choose a pre-defined category to assign to the
new signature.
9) The Data Match Threshold is used to define how loosely or tightly defined the signal
pattern is. The Data Match Threshold value is 70%, and the user can change this to any
