GUI MAIN MENU
5.2.1 FILE
• There are shortcuts available for Run/Stop, Mute, and Exit.
• When Tips are turned on a message will appear when Span exceeds the linear RBW range.
• Import allow the user to copy a previous GUI’s support files and reuse that GUI’s configuration files for
the SA List and LO Offset Menu.
• Create JPG and HTML are two options for capturing a screen shot of the GUI and saving it to a file or
printing.
5.2.2 DISPLAY
• Video color flip changes the graph colors for low or high lighting conditions.
• Spectrum flip is used for when a signal from a low-side injection LNB is monitored.
• Clear active signal removes the active (white) waveform from the graph if not running.
• Clear stored signal removes the red waveform from the graph.
• Download memory downloads traces saved in the spectrum analyzer. This item is only enabled when
connected to a new PSA-2500C, SNG-2500C, or LAN default connection type PSA or MSA series
analyzer, but not a SitePlayer type.
• Save Single stores the active (white) waveform to a .SIN file. Older GUIs saved a single to a .AVC file
but the waveform data was in raw 8-bit format. The new format is semicolon-delimited and the waveform
data has been converted to dB.
• Display Single recalls a saved .SIN file and displays it in a red waveform.
• Record Stream stores the active (white) waveform to a .REC file. It is disabled when not running. Older
GUIs recorded to a .STR file but the waveform data was in raw 8-bit format. The new format is
semicolon-delimited and the waveform data has been converted to dB.
• Play Stream recalls a saved .REC file and displays it in a red waveform.
• Zoom In/Out allows the CF and Span to be quickly changed by left-clicking the mouse cursor within the
graph area. If the cursor is left-clicked and released without moving the cursor between click and release
then the GUI zooms out by doubling the Span and changing the CF to the frequency where you clicked. If
the cursor is clicked and dragged then released the Span is zoomed in and the CF is the center of the drag
range. The zoom is disabled when Delta, Pointers, or Alarm is on.
