EVAL-ADF411xEBZ1 problem

Question

Hello, I just received the evaluation board EVAL-ADF411xEBZ1 with an ADF4157 onboard. The software provided on the CD was not compatible but I managed to retrieve the latest working version from your website. I installed the driver for the USB / Parallel adapter as well as the ADF4153-4-6-7 PLL Software. When I launch the tool, the board is detected and the communication is established. However there is absolutely nothing on the RFout (SMA connector). 
 Any help will be appreciated!

Is the output working OK at 5800 MHz? 
 You can program the software to 580 MHz, but the evaluation board, at the moment, won't be able to output 580 MHz. This is because the VCO on the board can only output frequencies from 5725 MHz up to 5875 MHz. You can look at the VCO's datasheet here: http://pdf1.alldatasheet.com/datasheet-pdf/view/398465/ZCOMM/V940ME03-LF.html 
 If you want 580 MHz, you will need to de-solder the V940ME03-LF VCO and replace it will a pin compatible VCO that can output 580 MHz. You can find one here: http://www.zcomm.com/vcopsg/searchResults_V.aspx?item=V 
 Ensure the replacement VCO is compatible with the V940ME03-LF.
