[TX Pulse] Pulse width changes according to range and shift values. However,
when long range detection or better resolution is your objective,
you can manually adjust the pulse width. the available settings are:
• [1/4]: Higher resolution, however range is lower than the [1/2]
setting.
• [1/2]: High resolution, however range is lower then the [Std] set-
ting.
• [Std]: Standard (default) setting. Range and resolution are bal-
anced.
• [×;2]: Higher range than [Std], however resolution is lower.
• [Manual]: Adjust the pulse width manually.
[Pulse Length] Available only when [TX Pulse] is set to [Manual]. A low setting
gives a higher resolution, however the range is lowered. A high set-
ting give a longer range, however the resolution is lowered.
Rx bandwidth is automatically set according to [TX Pulse] → [Pulse
[RX Band]
Length].The [Normal] setting provides good performance. If noise
is a problem switch to [Narrow]. For better resolution, select [Wide].
[Manual] enables manual setting of Rx band width, at [RX Band
Width].
[RX Band Width] Operative when [Manual] is selected at [RX Band]. A small value
decreases the noise. On the other hand, a large value gives better
resolution.
