The driver is not signed - Please install anyway
On first installation, WINDOWS will come up with a message stating that
the driver is not signed. Please install the driver anyway.
After the driver installation is complete, start the polarizationNAVIGATOR™
software.
Starting with revision 1.5 of the Photonic Application Suite, we are using
the libusb-win32 driver package (For more details, refer to User's Guide,
Part No. N7781-90001). The main reason for this change is the availability
of this driver package for 64bit operating systems.
If you connect an N778x instrument through USB to the PC (power it up
and wait until it is recognized by Windows) and is not recognized by the
Photonic Application Suite software, please check the computer’s Device
Manager (in Windows XP: right-click
My Computer
, then select
Properties
, then switch to tab
Hard ware
, then click
Device Manager
).
If USB drivers have been installed for the corresponding instrument with a
PAS revision less than 1.5 installed on the PC, they will be listed as
Keysight Technologies N778x USB Instruments in the section Universal
Serial Bus controllers.
If USB drivers have been installed for the corresponding instrument with a
PAS revision 1.5 or higher installed on the PC, they will be listed as
Keysight Technologies N778x USB Instruments (lib) in the section
libusb-win32 devices.
NOTE
When an N778xB instrument is connected to the USB bus, it will not be
listed in the Keysight Connection Expert.
NOTE
If you want to revert to a version of the Photonic Application Suite less
than 1.5, the old USB drivers will be installed on the PC again, but they
are not necessarily applied to N778x instruments. Below you will find
instructions on how to apply the correct drivers.
