1.9 Choosing a Pulse Length
The pulse length in use appears at the top left position on the screen. Appropriate pulse lengths
are preset to individual range scales and custom setups. If you are not satisfied with the pulse
length setting on the 1.5 nm or 3 nm range, you may change it as below. Use a longer pulse when
your objective is long range detection, a shorter pulse when resolution is important.
