Window Control Keys
Window Control Keys
The instrument provides three front-panel keys for controlling windows. They are Multi Window, Zoom,
and Next Window. These are all “immediate action” keys.
Multi-Window
The Multi Window front-panel key will toggle you back and forth between the Normal View and the last
Multi Window View (Zone Span, Trace Zoom or Spectrogram) that you were in, when using the Swept SA
measurement of the Spectrum Analyzer Mode. It remembers which View you were in through a Preset.
This “previous view” is set to Zone Span on a Restore Mode Defaults.

Zoom
Zoom is a toggle function. Pressing this key once increases the size of the selected window. Pressing the
key again returns the window to the original size.
When Zoom is on for a window, that window will get the entire primary display area. The zoomed window,
since it is the selected window, is outlined in green.
Zoom is local to each Measurement. Each Measurement remembers its Zoom state. The Zoom state of
each Measurement is part of the Mode’s state.
Data acquisition and processing for the other windows continues while a window is zoomed, as does all
SCPI communication with the other windows.
