RIPEX-470: 470-512 MHz
RX frequency**
Receiving frequency, the same format and rules apply.
Note : By default, the TX and RX frequencies are locked together and change in one field is mirrored
in the other. If clicked, the lock is removed and different TX and RX frequencies can be entered.
Channel spacing [kHz]**
List box: possible values
Default = 25 kHz
The wider the channel the higher the posible Modulation rate.
Modulation rate [kbps]
• Approval
List box: possible values
○
CE
Radio parameters meet the requirements of ETSI EN 300 113
○ FCC
Radio parameters meet the requirements of FCC part 90
CPFSK modulations have approx. 20% higher frequency deviation compared to CE, so the re-
ceiver sensitivity for the same modulation (data rate) is approx. 1-2 dB better.
○ Others
There are no official Radio test reports for CE 6,25 kHz and FCC 25 kHz channel spacings as
yet. However “Others” enables setting of Modulation rates for these options.
• Modulation rate [kbps]
List box: possible values
Default = 16DEQAM
Possible values in list box are dependent on the Approval set. The two highest rates are available
only when the corresponding SW feature key is active.
Higher Modulation rates provide higher data speeds but they also result in poorer receiver sensitivity,
i.e. reduced coverage range. Reliability of communication over a radio channel is always higher
with lower Modulation rates.
RF power [W]**
List box: possible values
Default = 5 W
The range of values in the list box is limited to 2 W for high Modulation rates. 10 W is available only
for lower Modulation rates (CPFSK) and only when the corresponding SW feature key is active.
Note: Max. RF power for RipEX-470 is 8 W even if 10 W is set.
FEC
List box: possible values
Default = Off
