5.4.01 Virtual Reference Menus

5-54
The virtual reference mode is very similar to the single reference mode with internal
reference, and is the simplest of the three additional modes of operation.
NOTE: This mode is only suitable for signals at frequencies between 100 Hz and
2.0 MHz.
The mode is accessed via a sub-menu of the Configuration menu, as shown in
figure 5-34. Note that as with the main menu structure, shown in figure 5-1, it is
possible to return to the Main Display from any menu by pressing the Previous Menu
key, but this has been omitted from figure 5-34 for the sake of clarity. Except as
discussed in this and the following sections, the remainder of the instrument control
and display menus operate in the same way as in single reference mode.

When the Configuration menu is displayed and the Virtual Reference key is pressed,
the Virtual Reference menu, shown in figure 5-33, will appear.
