Description
1
Frequency band
Display the selected frequency band as shown in the figure above. It indicates that the start
frequency of the selected frequency band is 865000kHz.
2
Modulation/
demodulation mode
Display the selected modulation/demodulation mode, as shown in the figure above,
indicating that the current modulation and demodulation mode is set to 2FSK.
3
Tx mode
Display the current transmit mode. CW indicates the transmit carrier mode
4
Chanel signal
Display the channel signal (value of Frequencry Channel) as shown in the figure above, the
channel signal is 0. Therefore, both of the operating frequency and starting frequency is
865MHz.
5
Tx power
Display the currently set transmit power. As shown in the figure above, it indicates that the
current set transmit power is +20dBm.
6

On the basis of the operation shown in the above figure, short press K1 to enter Carrier Tx mode, and the
display is updated as shown in Figure 3-4 below.

Note
：
1. Under this interface, press K1 again to stop the current carrier transmission mode and return to the upper
menu (as shown in Figure 3-3). That is, the carrier transmission can be alternately enabled and stopped
by the K1 short press operation.
2. Under this interface, press K2 to exit CW Tx working mode and return directly to the main menu.
3. Since the CMT2310A-EM board is equipped with reserved Current Detect jumper terminals, the current
consumption under different transmit powers in the CW Tx mode of the CMT2310A can be tested out .
4. Since it is a carrier transmission, it is not related to the set rate/frequency offset combination parameter.
5. In the process of carrier transmitting, when the LED1 lights up, it indicates that it is in the transmitting
state and when the LED1 extinguished, it indicates that it exits the Tx state and LED1 will be extinguished.
