OPERATION
32
the LEFT ARROW key will jump the currently displayed span down one half screen to the next
set of lower frequencies. Your SPAN parameter will remain constant, but your START, STOP, and
CENTER parameters along with the CURSOR position will change as the spectral display pans.
- Click & Drag – Narrow: Clicking within the very top screen division and dragging with your finger
or the stylus in a downward motion will decrease or narrow the size of the displayed span. You
may also pan at the same time that you are narrowing the span by dragging downward
diagonally as opposed to straight down.
- Click & Drag – Expand: Clicking within the very bottom screen division and dragging with your
finger or the stylus in an upward motion will increase or expand the size of the displayed span.
You may also pan at the same time that you are expanding the span by dragging upward

one half of the current value until the minimum span is reached.
- Expand key: Pressing the EXPAND key will increase or expand the size of the displayed span by a
factor of two until the maximum span is reached.
- Max key: Pressing SHIFT + EXPAND (MAX) will increase or expand the size of the displayed span
to the maximum frequency span.

minimum frequency span.
Changing the Spectral Parameters
There are several ways to change the spectral parameters:
- With the stylus, double click any of the spectral parameters (Start, Stop, Center, Span). A virtual
keypad will appear on the screen. Using the virtual keypad, enter the desired value for the
selected spectral parameter, then press one of the unit keys (kHz, MHz, GHz) to initiate the
change. Press ESC to discard any changes.
- Select the desired spectral parameter with the stylus so that it is highlighted. Using the number
keypad on the OSCOR unit, enter the desired value, then press one of the unit keys (kHz, MHz,
GHz) to initiate the change.
- Select the desired spectral parameter with the stylus so that it is highlighted. Turn the rotary
knob to change the value of the selected spectral parameter.
