— State

can be saved between compatible FieldFox models. See note
in.“Saving and Recalling Files” on page 266.
— Trace+State
Saves the current trace and instrument settings to a
*.sta file. In SA Mode, all traces are saved. This file can be opened
ONLY by a FieldFox. When recalled, the FieldFox sweep is set to Hold.
— Picture (PNG) Saves a 640 x 453 pixel image of the FieldFox screen to
a *.png file. The picture does NOT include the softkeys.
— Data (csv)
Saves trace data from the current Mode to a *.csv file. This
format can be imported into spreadsheet software such as Microsoft
Excel. Column A is always the frequency at which the data is
measured.
——In SA Mode, all visible data traces are saved. Each trace is
saved to a separate column that is labeled with the Trace
State.
——In CAT and NA Modes, only the data trace is saved – not the
memory trace.
——In Power Meter (with Option 208 Frequency Offset Power
Sensor (FOPS)), all visible traces are saved. Each trace is saved
to a separate column labeled Output Power or Memory.
——In VVM Mode, NO data is saved.
Insert only ONE USB Flash Drive in the FieldFox when saving or copying
files.
When using RTSA, the Density Spectrum information is not saved using
