Spectral Search (Sweep) Operating Mode
The Spectral Search (Sweep) Mode is used to get an overall view of the spectral components in a given frequency band. It
sweeps across a frequency band, from start to stop frequency, displaying the amplitude at each frequency step.
The user defines the frequency band by entering a start frequency, a stop frequency, and a step increment. The BDS
produces power spectral density information for each detected frequency in the band in accordance with the step
increment value (Fig. 1).

Arc Detection
The BDS has the ability to locate and report arc/transient events. The user can define the parameters of what a transient
may look like in their system, specifying arc length, and impulse change in dB. This feature is available in both Standard
Tracking and Spectral Search modes and in both 12-bit and 8-bit resolution.

BDS Sensors
The BDS requires a non-intrusive passive RF sensor. The sensor is purchased separately based upon the specifica-
tions of the end user’s requirements.
