The Front Panel at a Glance
1.  
This hardkey allows you to preset the power meter if you are 
currently working in local mode (that is, front panel operation). In 
local mode a confirmation pop up window is displayed prior to a 
preset being carried out. However, if you are in remote mode (that 
is, GP-IB, RS232 or RS422 operation), then pressing this hardkey 
places the power meter in local mode provided local lock out (LLO) 
is not enabled. 
2. Hardkeys relating to the display layout.
 This hardkey allows you to select the upper or lower 
measurement window on the power meter’s display. The window 
which is selected is highlighted by a shadowed box. Any 
measurement setup you create is implemented in the selected 
window.
 This hardkey allows you to choose either a one or a two 
window display.
