In order to use the instrument: 
1.  If you use a PCIe link to control the M8195A, the AXIe chassis must be 
switched on before you start the PC. If you use an USB link to control the 
M8195A, it’s not mandatory that the AXIe chassis is powered and has 
booted prior to turn-on the PC.   
2.  Start the M8195A Soft Front Panel (Start > All Programs > Keysight 
M8195 > Keysight M8195 Soft Front Panel). The user interface will display 
the VISA resource strings for different kinds of connection. 
3.  Using the appropriate VISA resource string you can:  
  Start the Soft Front Panel (Start > All Programs > Keysight  M8195 > 
Keysight M8195 Soft Front Panel). 
  Control the instrument with your own application using the M8195 IVI 
Drivers or add it as a LAN instrument in the Keysight Connection 
Expert (TCPIP0::localhost::…) and control it using SCPI (with e.g. the 
VISA Assistant or your own application). 
You must start the M8195A Soft Front Panel in order to send SCPI commands to 
the instrument.
