Acquisition Settings
Signal acquisition parameters can be easily changed to tradeoff system performance parameters. If a high
measurement rate is required, then the maximum signal integration time can be reduced to decrease
measurement times at the expense of somewhat reduced sensitivity and maximum range. Optical transmit
power can be increased by the setting loaded into the Laser Power Register. High pulse power may need to
be compensated with an increased spacing between pulse bursts to maintain an acceptable laser duty cycle
based on thermal derating requirements. If the length of the correlation record is increased to allow for
longer range measurements, increased processing time will decrease the measurement rate.

Maximum acquisition count sets the maximum number of acquisition cycles
with a maximum value of 255. In most cases an acquisition of 128 is
adequate.
Correlation record length establishes the portion of correlation memory
allocated to the return signal. The value is broken in to upper and lower
