Sensors and Sweeps
Locate your sensor by name. Then find the appropriate sweep in
the same row. In general, it is best to use the lowest sweep range
that covers the sensor frequencies.
Sweep Frequencies
If your sensor is not listed above, check your sensor calibration
sheet to find the lowest and highest frequencies in the calibra-
tion. Then choose the sweep that is closest to those frequencies.
