3.8.3 Set Scanner Unit (TXRX Setting)
This function enables the setting of detail information about an antenna.
Procedures 1 Open the TXRX Setting menu by performing the menu operation below.
Main
→ RADAR Menu
→ TXRX Setting
The TXRX Setting menu will appear.
Detail information about antenna operation can be set by changing the settings of the
menu items.
[1] PRF Fine Tuning
･ Fine-tune the transmitting repetition frequency of the transmitter in the range 90 to 100%.
･ If radar’s interference patterns are concentrically displayed, increment or decrement the set value by 3 to
4 in order to heighten the effect of interference rejection.
･ One of 32 levels 0-31 can be set.
[2] Stagger Trigger
･ The interference reduction function is activated by using the transmission repetition frequency control of
the transmitter.
･ This function is effective when radar interference does not go away.
Off : Stagger Trigger is not used.
On : Stagger Trigger is used.
[3] PRF
･ Select the operation mode the transmitting repetition frequency of the transmitter.
Normal : Standard mode : Both appropriate gain and magnetron’s life
expectancy are maintained.
Economy : Power saving mode : Gain slightly lowers, but the service
life of magnetron is prolonged when short
pulses are used.
High Power : High gain mode : Gain improves when long pulses are used,
but the service life of magnetron is slightly
shortened.
[4] Ice Class Standby Mode
･ In this mode, the antenna is rotated when transmission is in the standby state.
･ This mode is effective to prevent the antenna's rotating shaft from freezing.
Off : The ice class standby mode is not used.
When transmission is in the standby state, the antenna also stops rotating.
On : The ice class standby mode is used.
When transmission is in the standby state, the antenna rotates.
