Mode
With this parameter you can select the transmitted mode (Feld, PSK-105 or PSK-245).
Magnitude
With this you can set the magnitude (maximum amplitude) of the transmitted signal. The amplitude value is set as an absolute value. When 16-bit processing is used then maximum magnitude will be 32767. If 8-bit processing is used the maximum is 127.
Sum to RX
With this switch, you can select the input signal of the HELL transmission block added to HELL transmission generated by the block. This is very useful feature, when you would like to build multicarrier transmissions (just put several transmitters in chain with this switch set on)
