centre frequency, which is dependent on the antenna
dimensions. The unit has one optical connector for the
transmitter trigger, a connector for a battery pack, a power
switch and a LED.
See Figure 4.2.
When flashing, the LED on the transmitter electronic indicates
trigger pulses are being received from the Radar Control Unit.
No light indicates no power is being received by the
electronics. A steady light indicates that no Trigger pulses are
received from the Radar Control Unit.
NOTE: As soon as the power switch is turned on with a battery
connected the transmitter starts firing pulses. There is a short
"warm-up" sequence of the antenna whereby it is
recommended to turn the electronics on a few minutes before
data collection starts. A good rule of thumb is to turn on the
transmitter first when preparing for a survey.
