Thus, the overall dynamic range at 1MHz bandwidth (approx. 1 msec transmit pulse) is 88+6+4
= 98dB. For a 0.5 msec pulse the dynamic range would be reduced to 95dB; but it would
increase to 101dB for a 2.0 msec pulse. An actual calibration curve demonstrating this
performance is shown in Figure 2–1, for which the RVP8’s digital bandwidth was set to
0.53MHz and external signal generator steps of 1dB were used over the full operating range.
