Advanced TX Controller Window
Output Frequency (MHz)
The transmit frequency can be changed by entering the new desired
frequency in this field. Values outside the range supported by a
particular transmitter type will be rounded to the highest of lowest
supported frequency as appropriate.
The transmit frequency can be set in step sizes of 250kHz.
Modulation Bandwidth
For the SOLO2 transmitter products, the modulation bandwidths 8, 7 or
6MHz can be selected.
For the SOLO4 transmitter products, the modulation bandwidths 8, 7, 6
or 2.5MHz can be selected. If the Ultra Narrow band upgrade has been
purchased the 1.25MHz will also be available to select.
The normal mode of operation is 2.5MHz.
Modulation Output
This control is used to turn on and off the RF output. After a
configuration change, the output always reverts to OFF.
Narrow Band FEC
This option applies to SOLO4 transmitters only. The default FEC is 2/3,
however improved range operation can be achieved by selecting FEC
1/3. FEC 1/3 will improve signal range by 3dB. However FEC 1/3
reduces link capacity to 1.2Mb/s therefore reducing picture quality.
