OKI Semiconductor
Initial value: 1EBBh (–5.3 dBm0)
Compute the setting value using the following equation when changing the detection level X.
Equation: 10^((X – 3.17)/20)*2/PI*32768
Example: Detect level of –5.3 dBm0
To stop the noise detection function, write 7FFFh to the above described internal data memory
(TONE_TXDET0_N_TH).
Initial value: 0028h (5 ms)
Use the following equation when changing the timer value.
Equation: Guard timer value in ms/0.125 ms
Example: 5 ms
5/0.125 = 40d = 0028h
Initial value: 0028h (5 ms)
Use the following equation when changing the timer value.
Equation: Guard timer value in ms/0.125 ms
Example: 5 ms
5/0.125 = 40d = 0028h
Initial value : -
The detection frequency can be changed. Contact our sales personnel if it is desired to change the detection
frequency.
