VNWA 3 Expansion board fitting:

  • VNWA 3 with serial numbers of A2200 and below:  Retro fitting the Expansion board will require soldering of the SIP connectors to the Main PCB assembly and removal of a resistor. Soldering should only be carried out by persons who have the required skills and previous experience of this type of work. See the VNWA 3 Expansion board Manual for details.  
    Note - fitting the optional SMA external clock connector requires drilling of a 8mm hole in  the Main chassis.

  • VNWA 3 with serial numbers of A2201 and higher: Retro fitting the VNWA 3 Expansion board consists of plugging in the Expansion Board and removing a SMD jumper on the main PCB using a soldering iron. See the VNWA 3 Expansion board Manual for details.
    Note: - a 8mm hole is already present for fitting optional SMA external external clock connector.
