 ===== Software Interface ===== ===== Software Interface =====
-==== Main Controls ====+ 
 +The interface used to control the circuit is described in this section. The are 3 regions of the software interface panel as shown below. 
 + 
 +1. Graphical control region : This contains all the buttons and numeric controls used to program the ADF41513. 
 + 
 +2. Register region : If anything is changed in the graphical control region, a register is highlighted in green. This indicates to the user that the register must be written by pressing the corresponding Write register button.  
 +Note: There are some controls where a dedicated button is used to update the register in the graphical control region. In these cases the write register button is not used.  
 + 
 +3. Log Window : This is used to show the most recent transactions to the user. A log can be saved of all activity in a session.  
 +

 + 
 +==== Device Connection ==== 
 + 
 +The device connection tab is displayed first after executing the software interface.  
 +From here, the user selects the device variant and the device configuration (single board or multi-board).  
 +After these are selected the user presses the Connect button to establish a connection.  
 + 
 +==== Main Controls Tab==== 
 === Reference Configuration === === Reference Configuration ===
 +
 +This section contains the controls associated with the reference frequency.
 +
 +== Reference Source ==
 +
 +By default, the board is configured to use the default 100MHz on-board reference crystal oscillator. If a different frequency external reference is used, this is changed in this control.
 +
 +== Reference Frequency ==
 +
 +This can only be changed if an external reference frequency is used. This value must match the external frequency applied.
 +
 +== Divider and Doubler ==
 +
 +These can be used to change the PFD frequency accordingly on the [[adi>adf41513|ADF41513]]. 
 +
 === Frequency Control === === Frequency Control ===
 +
 +In the frequency control section, the VCO output frequency can be programmed. This is done by inputting the desired frequency in MHz. After inputting the frequency, press the 'Update Frequency' button to update. 
 +
 === Phase Control === === Phase Control ===
-=== Hop Function ===+ 
 +The phase of an output signal can be incremented by specifying the value in the Phase Value field. The phase is calculated and can be updated by pressing the Increment Phase button.  
 +Phase resync is enabled by default within the initialization sequence. To set the phase resync time, set the CLK1 and CLK2 multipliers accordingly. Note: the phase resync time must be greater than the worst case lock time.   
 + 
 +==== 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.\\  
 +{{:resources:eval:user-guides:circuits-from-the-lab:hopfunction.png|}} 
 + 
 === 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 as shown below. 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|}}
 +
 +
 === 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.
