1. Interferer/Channel @ BER = 10
−3
, channel level is +10 dB above the typical sensitivity, the interfering signal is a random data signal (except
PSK200); both channel and interferer are modulated without shaping
2. FSK 50 kbps: 868 MHz, 200 kHz channel spacing, 25 kHz deviation, programming as recommended in Programming Manual
3. FSK 100 kbps: 868 MHz, 400 kHz channel spacing, 50 kHz deviation , programming as recommended in Programming Manual
4. PSK 200 kbps: 868 MHz, 400 kHz channel spacing, programming as recommended in Programming Manual, interfering signal is a constant
wave
5. Channel/Blocker @ BER = 10
−3
, channel level is +10 dB above the typical sensitivity, the blocker signal is a constant wave; channel signal
is modulated without shaping, the image frequency lies 2 MHz above the wanted signal
