DTF Wizard

Note: Maximum allowed distance and resolution per point is a com-

plex function of the cable and frequency settings. Use the DTF wizard if

the SignalHawk is having issues resolving these functions.

When the DTF Wizard soft key is pressed, a window with a set of adjustable vari-

ables will open in the display. Left/right arrow keys change the fields, while up/

down arrow keys, the thumbwheel, and the number pad change each field’s

value.

The DTF Wizard takes the guesswork out of setting up a fault-location measure-

ment by requiring knowledge of the type of cable used in the system, total length

to the antenna and the desired accuracy of the location of the fault. The DTF Wiz-

ard automatically calculates and sets the best parameters of stop distance points

and frequency settings.

A Cable List soft key is available. Pressing this will display a series of cables to

choose from. The settings for the selected cable will then be displayed in the

variable fields. The variables are:

Vp (Velocity)

Sets the speed of the signal going through the cable being measured.

Note: The wizard will automatically apply velocity and loss

to their fields.
