Wanted signal 3 dB above the
sensitivity level, CW jammer at
operating frequency, BER = 10 −3
Wanted signal 3 dB above the
sensitivity level, CW jammer at
adjacent channel, BER = 10 −3 .
Measured at ±100 kHz offset.
See Figure 16 to Figure 19.
Wanted signal 3 dB above the
sensitivity level, CW jammer at
image frequency, BER = 10 −3 .
102.4 kHz channel filter
bandwidth. See Figure 16 to
Figure 19.
Image rejection after calibration
will depend on temperature and
supply voltage. Refer to section
12.6 on page 35.
Wanted signal 3 dB above the
sensitivity level. CW jammer is
swept in 20 kHz steps within ± 1
MHz from wanted channel. BER
= 10 −3 . Adjacent channel and
image channel are excluded.
See Figure 16 to Figure 19.
Wanted signal 3 dB above the
sensitivity level, CW jammer at ±
1, 2, 5 and 10 MHz offset,
BER = 10 −3 . 102.4 kHz channel
filter bandwidth.
Complying with EN 300 220,
class 2 receiver requirements.
Ratio between sensitivity for a
signal at the image frequency to
the sensitivity in the wanted
channel. Image frequency is RF−
2 IF. BER = 10 −3 . 102.4 kHz
channel filter bandwidth.
