dBm

Measured directly by applying

two tones and measuring the

resulting difference tone

amplitude.

Image frequency suppression

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 =

−3

Spurious reception

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.
