Throughout the system the touch screen acts as a mouse. For right click
operations there is an always-on-top icon, which will turn the next touch
to a right-click touch. If this icon is not on the screen it can be reactivated
from the system tray by clicking on the pm-icon and setting a mark next to
the Right button. You will have to quit the polarizationNAVIGATOR™ in
order to access the system tray.
In addition, the knob on the front plate can be used for cycling through
lists of buttons and for changing numerical values. Pressing the wheel is
similar to pressing the OK button and will push a button or accept a
numerical value. The ESC key will toggle between menu access (File, Edit,
View, etc.) and button access and it will abort changing numerical values.
The Left Arrow and Right Arrow buttons will switch between different
graphs (PMD, PDL, DOP, Stokes-Parameters, etc.) and will change the
cursor position in dialog boxes. For most dialogs, special
on-screen-keyboard-dialogs will appear. In case you need to enter
additional characters, Windows provides an always-on-top on-screen
keyboard, which can be activated by pressing the wheel twice in quick
succession. For using this feature, the polarizationNAVIGATOR™ has to be
running. A link to the on-screen keyboard is placed on the desktop, which
can be used otherwise. When powering up the instrument, it will log on
automatically. To login again after logging out, you can use the on-screen
keyboard which is displayed at the bottom of the login screen. Enter
username and password provided at the beginning of this section.
Furthermore, USB and PS/2 keyboards and mice can be connected to the
N778xBD.
Using any of these controls, choose an application and use the control
buttons for setting the specific parameters and controlling the application.
Usually the horizontal row of buttons switches between several subsets of
functions or parameters, which are then listed as a column of buttons to
the right. There may be more items in a horizontal or vertical set than
buttons. In this case More will be among the set of buttons. Usually you
will find an Exit button, which will stop the active application. The actual
parameters and functions are similar to those described in the specific
chapters of the manual (N7781B/BD: Refer to "Application: Polarimeter" in
User's Guide, Part No. N7781-90001 and for N7788B/BD: Refer to
"Application: PMD/PDL (PMD/PDL/Loss)" in User's Guide, Part No.
N7781-90001).
