The Up/Down button (PB1) moves the arrow up and down the LCD screen.
The arrow is used to highlight the function that will change when the user presses the '+' and '-' buttons. In the
screen shown above, 'Function:' is highlighted, pressing the '+' and '-' buttons will switch the mode of operation
between demonstration mode and lab mode.
Moving the arrow down to the ' =>Demo Mode: TRx' will allow the user to change between TRx, RX and TX
functionality via the '+' and '–' buttons.
For the purpose of this introduction to the system we shall operate in 'Demonstration Mode'. Please ensure Demo
mode is selected and TRx is enabled. The same selections should be made on both of the software development
boards.

7.1.3. Screen 3: Setting up Further RF Parameters
On this screen, there may be a difference with respect to the screen shot available which is dependent on the
testcard installed in to the 40 pin connector. Several testcard options are available for the SDBC-DK3 (see website
for details). Typically, testcard variants include antenna diversity cards for use with antennas, single-ended Tx/Rx
testcards (also intended for use with antennas), and split Tx/Rx testcards designed for use with coaxial cable to lab
equipment (see "7.2. Lab Mode" on page 22 for more details).
