 +1. Download the software folder from the CN-568 product page. 
 +
 +2. Double click on the 'CN0548.exe'self extracting installer to start the installation process. 
 +
 +3. Follow the installation windows that appear, to install the software in the default location as shown in the screenshots below.

 +4. After the CN0568 software has installed, an installation window for the SDP drivers will appear. If the SDP drivers have not previously been installed on the machine, proceed with this installation step.

 +5. Load the custom firmware to the SDP-K1 board by dragging and dropping the 'SDP_K1_release.hex' file contained within the software download folder, to the SDP-K1 drive listed in the 'Devices and Drives' of the 'This PC' within windows explorer. This step only is only required to be done once as the image remains on the board after removal of the USB cable.

 +==== Hop Function Tab==== 
 + 
 +A frequency hop can be performed continuously between 2 frequencies within the Hop Function tab. VCO Freq. A and VCO Freq. B are the two frequencies that the user specifies for the hop. The dwell time at each frequency is input in the Time Delay field. A frequency hop is started by pressing the Start button. Likewise the frequency hop is stopped using the Stop button.\\

 === Dual Board Control === === Dual Board Control ===
 +A dual board configuration can be used when two boards of the same VCO variant are connected via a stacked connection from the Arduino style header. This first must be selected in the Board Configuration section prior to a software connection being established to the board. When using the dual board configuration, the user has the ability to select which board is being controlled through SPI writes by selecting the board in the Board Select drop-down box on the upper right within the main controls tab. This control is only visible if the dual board configuration had been selected at the connection stage. \\
 +
 +{{:resources:eval:user-guides:circuits-from-the-lab:boardselect.png|}}
 +
 +To use the dual board configuration, one of the boards needs to first be reconfigured to receive SPI on a different LE signal line. To do this, remove R41 on the upper board of the stack and insert R42 instead. \\

 === Other Functions === === Other Functions ===
 +
 +Some of the basic register controls of the [[adi>adf41513|ADF41513]] have been included in the Other Functions tab of the software interface. These controls are related to lock detect settings, PLL settings and the muxout signal. For information about the functionality of each control refer to registers 5, 6, 7 and 12 in the register map section of the [[adi>adf41513|ADF41513]] datasheet.
