Zeroing The Unit; Using The Usb Port - EXFO FVA-600 Guide D'utilisation

Zeroing the unit

The Variable Attenuator contains mechanical elements used to change attenuation.
It is a good practice to have the instrument mechanism return to the zero (home)
position to reestablish its relative position on the range of attenuation.
To perform a zeroing:
Press and hold
The screen displays ZERO while the zeroing is
performed. After the search is complete, the unit
returns to the attenuation that was previously in use.

Using the USB Port

The FVA-600 Variable Attenuator includes a USB port located on the side of the unit.
EXFO provides two installation kits to control the FVA-600 via the USB port.
One installation kit is for a computer using Microsoft Windows XP or
Vista (32/64 bits). This kit gives you the source code so you can set up a program
that better suits your needs. The source code is in C# and the project was
developed with Microsoft Visual Studio 2005.
The other installation kit is designed for the FTB-500. You can access the
application through the Tools (IPM) tab in ToolBox.
When you use either of the installation kits, the
remote-controlled unit displays REM. on its screen.
The unit returns to local mode when you exit the
software or if you disconnect from the USB port. The
screen displays RTL until you press a key, then the unit
can be controlled by the keypad.
