[Link]
The [Link] key is used to link and unlink display specific parameters, to perform a
function on both displays at once, or to temporarily link the display markers.
When an unlinked display specific parameter is highlighted (for modification), the Link
indicator (next to the top of the menu) reads either ‘DispA’ or ‘DispB’, whichever is the
active display. Parameter entry or selection modifies only the active display. To change
which display will be modified, press [Active Display].
When a linked parameter is highlighted, the Link indicator reads ‘Link’. Parameter entry
or selection modifies both displays at once.
To link or unlink a parameter, highlight the parameter and press the [Link] key. If the
Link indicator is shown in gray, then the parameter linking may not be changed.
Parameter linking is a convenient way of changing both displays together. For example,
Span and Start frequency may be linked while the Measurement is unlinked. This allows
the two displays to have different measurements over the same frequency span. Since the
Spans are linked, changing the Span does not require separate entries for each display.
When a function key, such as [Marker Max], is pressed, the function is performed on the
active display. If [Link] is pressed immediately before, then the function is performed on
both displays at once. [Link] only affects the next key pressed. If the next key is not a
function key then it has no affect. Linking affects each function differently. See the
function key definitions for more information.
When no parameter softkey is highlighted, turning the knob adjusts the marker position
in the active display. If [Link] is pressed, then the marker of the inactive display is linked
to the active display and the knob moves both markers together. Pressing a key will
cancel this link. If the key is a function key, its function will be linked.
[Print Screen]
The [Print Screen] hardkey allows you to print or plot the screen from any menu.
Configure printing and plotting in the [Output] menu and choose Print, Plot or Dump
Screen as the Hard Copy Button function to configure the [Print Screen] hardkey.
Pressing [<-] (backspace) will abort the printout. No other front panel operations may be
performed until printing is completed.
Command: PRNT, PLOT or DUMP
[Help/Local]
[Help/Local] provides on screen help for any key or softkey. Press [Help/Local] to enter
the on-line help system. Press [Help/Local] again for more information on the help
system.
When a host computer places the unit in the REMOTE state, no keypad or knob input is
allowed. To return to front panel operation, press the [Help/Local] key.
