applications that do not require the full receiver bandwidth. Six low pass filter settings are
available in the DPR300, and the exact filter cutoff frequencies depend upon the receiver
bandwidth selected.

5.1.8

High Pass Filters

These filters are available for eliminating undesirable low frequency energy from the
DPR300 receiver signal. High pass filtering can be used as a means of providing faster
receiver recovery from strong signals such as the excitation pulse or strong interface echoes.
Six high pass filter settings are available in the DPR300.
