Note1
[XTR-434]: test as Fig. 3 , RF IN –100 dBm, FM Deviation ± 25KHz and Modulation frequency 40 KHz.
[XTR-434L]: test as Fig. 3 , RF IN –103 dBm, FM Deviation ± 25KHz and Modulation frequency 20 KHz.
Note2: The R.F. emission measure has been obtained by direct connection of the spectrum analyser to XTR module pin 2.
Note3: Switch-on time is the time required by the device to acquire the declared characteristics, from the very moment the enable
Note3: signal is applied.
Note4: Values obtained with a 10KΩ load applied.
TX/RX Enabling
Pin 15 [TX ENABLE] and 16 [RX ENABLE] can acquire the following status:
Pin 15 TX ENABLE
Pin 16 RX ENABLE
