Menu

values may be changed using the Up/Down arrow key or keypad.

 

Choosing AMPLITUDE in FREQ or DTF measurement modes causes the soft

 

keys, below, to be displayed and the corresponding values to be shown in the

 

message area.

 

Pressing the LIMIT key on the keypad will also call up this menu.

 

￿ TOP — Opens the top parameter for data entry and provides for setting the

 

top scale value. Press ENTER when data entry is complete.

 

￿ BOTTOM — Opens the bottom parameter for data entry and provides for set-

 

ting the bottom scale value. Press ENTER when data entry is complete.

 

￿ LIMIT — Opens the segment limit line selection table and the segment limit

 

line sub menu (see below). Use the Up/Down arrow key to select one of the

 

five segment limit lines. Press the ENTER key to select.

 

￿ LIMIT BEEP — Toggles the Limit beep sound on or off. When on, the Site

 

Master sounds a beep when the measured value is above any of the segment

 

limit lines.

Segment

Provides for setting each of the five segment limit lines. Selected values may be

Limit Line

changed using the Up/Down arrow keys or the keypad.

Sub-Menu

￿ ON/OFF — Toggles the selected segment limit line on or off.

 

 

￿ EDIT SEGMENT — Opens the selected segment limit line parameter table

 

for data entry. Use the Up/Down arrow and ENTER key to select the segment

 

limit line parameter (start freq, start limit, stop freq, or stop limit) to edit.

 

Use the Up/Down arrow keys or the keypad to edit the parameter value.

 

Press the ENTER key when done editing, or press ESCAPE to revert to the

 

previous value.

 

￿ SCROLL SEGMENT — Opens the selected segment limit line for scrolling.

 

Use the Up/Down arrow key to scroll the selected limit line up and down the

 

amplitude display. Press the ENTER key when done scrolling, or press ES-

 

CAPE to revert to the previous value.

 

￿ FULL SPAN — Span the selected segment limit line to the full frequency

 

display (F1 to F2).

NOTE:

The Start and Stop limit values remain at the segment limit line value.

 

￿ SELECT SEGMENT — Opens the segment selection table. Use the

 

Up/Down arrow key to select the current active segment limit line on the dis-

 

play.

 

￿ BACK — Returns to the Amplitude (or Limit) menu.

SWEEP

Displays the Sweep function soft key menu for the current operating mode.
