Display
When you set the display to on, the softkey menu displayed depends on
which math operator you select. When magnify, versus, or FFT magnitude is
the operator, the function scaling softkey replaces the vertical softkey.
The display softkey turns on the display of the function, and it allows you to
adjust the size and position of the newly generated waveform (function) for
easily viewing the waveform and for easily making measurements. You can
use the knob, arrow keys, or keypad to size and position the function.
Software expansion is used to resize the function when you change the
display controls. It does not change the way the hardware acquires the data.
When display is set to on, the function is calculated and displayed. Turning
the display to off ends function computation and erases the function from the
display.
Function 1 is displayed in the same color that is used to display signals from
slot 1, and function 2 is displayed in the same color that is used to display
signals from slot 2.
Vertical
You can set the scale to track the source waveform or you can adjust the
scale manually with the scale and offset keys.
In the HP 54710A, 54710D, 54720A, and 54720D, functions are limited to 32K
points. On a waveform exceeding this length, functions are calculated on the
first 32K points of the waveform.
Scale
Scale changes the vertical size of the function, so that it is not clipped or too
small on the display.
Offset
Offset positions the function vertically on the display.
