PathTrak Field View (OPT3): PathTrak Mode Operation

145

When you’re in the Dual Marker mode, this key toggles the

cursor between A and B. Select this when you want to compare

the amplitude at two different frequencies for either the Local or

the Remote trace.

This soft key selects the Peak Search function. When selected,

the active marker is automatically positioned at the frequency of

the highest amplitude in the spectrum graph of the current

active trace. This option is available in both Single and Dual

Marker modes.

LEVEL Submenu

Selects the LEVEL submenu. Use the Level soft key to adjust

the vertical parameters of the graph. These parameters include

reference level, scale, and maximum hold.

The reference level is located on the top line graph. You adjust

it using the up and down diamond keys, or by entering a

numeric value using the keypad and pressing the Enter key.

The scale parameter (1, 2, 5, 10, and 20 dB/div) can be

adjusted only with the up and down diamond keys. After you’ve

set the scale, press the Level soft key to return to the

PATHTRAK screen.

The Maximum Hold function ensures that the highest amplitude

at each frequency over multiple sweeps is displayed. If

Maximum Hold is on, you will see that the small icon at the

upper right corner of the display is darkened. As multiple

sweeps occur, the maximum level trace will change only if new

sweep levels exceed the levels of the current trace. A half-tone

trace will show you the saved data when Maximum Hold is

enabled.

Node List Mode

The Node List contains the current list of nodes available from the PathTrak

system. The Node List can be viewed at any time; however, the SDA-5000

field receiver must be connected to the amplifier/node test point in order to

update the list. After it’s updated, the list is stored in memory.

Use this soft key to view the Node List. This screen displays a

list of nodes available from the PathTrak system. You can view

either all nodes in the system or only the broadcast nodes. If the

node you want to view is not being broadcast, contact the

PathTrak system administrator to request activation. You must
