RADIO PARAMETERS (on 410-475 MHz)

This product offers the radio settings for user to select:

•

Channel spacing: 25 kHz, 20 kHz or 12.5 kHz

•

Frequency can be any 6250 Hz divisible frequency with 12.5kHz and 25kHz channel
spacing options

•

Frequency can be any 10000 Hz divisible frequency with 20 kHz channel spacing option

8.1

Transmitter

The output power of the transmitter is adjustable (see the table below for available values). The
greatest allowable power depends on limits set by local authorities, which should not be
exceeded under any circumstances. The output power of the transmitter should be set to the
smallest possible level such that it still ensures error free connection under variable conditions.
Excessively high output power levels used in short link spans can cause interferences and affect
to the overall operation of the system.

Transmitter output power levels

Output power (mW) Output power (dBm) 410-475 MHz
10 mW

+10 dBm

✓

20 mW

~+13 dBm

✓

50 mW

~+17 dBm

✓

100 mW

+20 dBm

✓

200 mW

+23 dBm

✓

500 mW

+27 dBm

✓

1000 mW

+30 dBm

✓

The antenna (or a 50 Ohm attenuator) should be always connected to the antenna connector
while the transmitter is being used in order to guarantee the maximum lifetime of the
transmitter.
