To enter a setting or parameter value, press the sequence of number keys
representing the numerical value, and then press the appropriate terminator key.
The numbers appear on screen as you type them, but they are not entered until
you press the terminator key.
If you make a mistake, you can correct it any time prior to pressing a terminator
by repeatedly pressing [BKSP] (the backspace key) until the incorrect number
disappears and then typing the correct value.
The terminator keys ([W], [X], [Y], and [Z]) determine the units and enter the
data. Each key can represent several units, but they are context-sensitive, and the
2715 will determine the intended unit based on the parameter or setting you are
attempting to modify. For instance, [X] can represent MHz, ms, or mV, and if
you are attempting to enter a sweep rate, the 2715 will correctly interpret the
units as msec when you press [X].
To enter a value of 20 milliseconds, press [2] [0] [X].
Whereas, to enter 20 microseconds, press [2] [0] [Y].
Entering a value for the sweep rate also removes the sweep rate parameter from
automatic selection. To return to automatic selection, you press [AUTO] in the
SWEEP function block on the front panel.
There are three ways to exit from a menu:
H
Many selections cause the 2715 to revert automatically to the measurement
mode it was in before calling up the menu. In some cases a small delay is
provided between making the selection and reverting to the spectral display
to enable you to see the status indicator at the end of the menu line change.
However, the change is also reflected in the on-screen readouts in many
cases, or by the nature of the spectral display itself.
The following prompt is displayed at the bottom of all menus prior to
making a selection:
PRESS ANY MENU KEY TO EXIT
PRESS BKSP FOR PREVIOUS DISPLAY
H
Simply pressing a menu key returns instantly to the spectral display. You can
use this technique if you decide not to make a selection.
H
Pressing the backspace key, [BKSP], returns to the previous menu. If there is
no previous menu, you return to the spectral display. The backspace key can,
therefore, be used to return to a previous menu to alter a selection, or to back
entirely out of a menu and return to the spectral display.
In general, menus are not reproduced here. It is intended that you call up menus
on the 2715 and follow along with the examples in this section as they are
described. For a handy reference, consult Operating Basics.
