Digital Receiver Filters
The EPOCH 6LT has a total instrument bandwidth of 0.2–26.5 MHz at
−
3 dB. The
instrument offers 8 standard fixed digital filters designed to improve the
signal-to-noise ratio by filtering out unwanted high and/or low frequency noise.
Because of the shifting frequency spectrum in most materials, you may need to adjust
the filter settings. In most cases, you should select either a broadband filter or a
narrow-band filter that covers the frequency of the transducer being used.
The EPOCH 6LT contains the following eight (8) standard filters.
•
0.2 MHz–1.2 MHz
•
0.2 MHz–10.0 MHz
•
0.5 MHz–4.0 MHz
•
1.5 MHz–8.5 MHz
•
2.0 MHz–21.5 MHz
•
5.0 MHz–15.0 MHz
•
8.0 MHz–26.5 MHz
