Measured directly by applying
-5
dBm two tones and measuring the
-17
dBm resulting difference tone
amplitude.
56
dB Ratio between sensitivity for a
signal at the image frequency and
the sensitivity in the wanted
channel with an inverted signal.
The image frequency is centered
-2 MHz from the center of the
wanted channel. The signal
source is 1Mbps, NRZ coded
data, ±250 kHz frequency
deviation, signal level for BER =
10^−3
80
dB Ratio between the sensitivity for
an unwanted frequency and the
sensitivity in the wanted channel.
The signal source is a 1 Mbps,
NRZ coded data, ±250 kHz
frequency deviation, swept over
all frequencies 2400 – 2483.5
MHz. Signal level for BER = 10^−3
Adjacent channels and image
channel are excluded.
