Conventions
The following typographical conventions are used in this manual:
HNames of front-panel controls and menu item names are in bold with the
same case (initial capitals or all upper case) as they appear on the unit itself.
For example, SETUP, Sub-sequence.
HSections 2, 3, and Appendix B describe the instrument functions by using a
table to list a sequence of steps. Each operating procedure is presented in
order, starting with step 1, and progresses until the end of the procedures.
Execute the action in the top-left table entry first. Then execute actions from
left to right along each row. When you are done executing the steps in one
row, move to the left end of the next row down, and continue executing the
listed steps until the end of the table.
HWhen steps require that you make a sequence of selections using menu
buttons, an arrow ( !) marks each transition between menu buttons. Refer
to Menu Notation on page 2-14 for further information.
For pop-up menus, use the general-purpose knob to select items from the
menu list. Operations, such as Operation 6 (below), do not involve pressing
the buttons shown in the row above, but rather are descriptions of operations
to be performed.
