Description

 

 

General purpose knob

Located in the upper right corner of the front panel, navigates among menu choices or changes values,

 

depending on the feature you are currently using. In general, the knob continues to perform the assigned

You can use this knob with the following functions:

 

H Select button. In the Configure menu, use the knob to scroll through the list of submenus, and then

 

press the Select button to open the selected submenu. In some modes of operation, the Select

 

button LED will stay illuminated. This indicates that you can press the Select button to toggle the

 

general purpose knob between controlling two items.

 

H Line Select. Use the knob to select the desired video line. In some cases, the knob will automatically

 

return to Line Select mode after being assigned to another function.

This red LED illuminates when a hardware fault is detected within the instrument, such as under/over

 

voltage of a power supply.

 

The green ON/STBY LED and the red FAULT LED indicate instrument status and do not report input

 

signal problems. Table 2--2 lists the LED status conditions and what they mean.
