This function enables the setting of detail information about a scanner
Procedures 1 Press [RADAR MENU] key twice.
Press [5] key.
The TRX 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.
• The same operation can be performed by pressing the
[TX/STBY] key several times.
• One of 32 levels 0-31 can be set.
[2] Jamming
• Use the jamming function to control the transmitting repetition frequency of the transmitter.
• This function is effective when interference patterns caused by radar equipment of the same model do
not disappear.
OFF : Disables the jamming function.
ON : Enables the jamming function.
[4] XMIT Repitation FREQ
• Select the operation mode the transmitting repetition frequency of the transmitter.
NORMAL Standard mode: Both appropriate sensitivity and magnetron’s life
expectancy are maintained.
ECONOMY Power saving mode: Sensitivity slightly lowers, but the service life of
magnetron is prolonged when short pulses are
used.
HI POWER High sensitivity mode: Sensitivity improves when long pulses are used,
but the service life of magnetron is slightly
shortened.
