SA (Spectrum Analyzer) Mode
SA Mode Settings
— Gate Delay Effectively moves the gating area left (negative delay) or
right (positive delay) relative to the trigger event. Enter a value using
the numeric keypad, the
arrows, or the rotary knob.
When you have properly setup the Gate Trigger, Width, and Delay using the
Gate View measurement, you can turn Gate View OFF to return to the full
screen non-zero span measurement with FFT Gating ON, the RBW set, and the
Trigger settings active.
Single / Continuous / Restart
This setting determines whether the FieldFox measures continuously or only
once each time the Single or Run / Hold +/- button is pressed. Use Hold /
Single or to conserve battery power or to allow you to save or analyze a
specific trace.
How to set Single or Continuous
— Press Sweep 3 .
— Then choose one of the following:
— Continuous
—— ON Causes the SA to make continuous sweeps. This is the
typical setting for making measurements. Each Run / Hold +/-
press causes the SA to toggle between continuous sweep and
Hold.
—— OFF Causes the SA to Hold. Each Run / Hold +/- or Single
press causes the SA to make ONE sweep, then Hold. The Hold
annotation changes to an arrow --> while the sweep occurs.
— Single Automatically sets Continuous OFF and causes the SA to make
ONE sweep, then Hold.
— Restart Resets the Average counter to 1. The Average counter also is
used with MaxHold and MinHold Trace States. Learn more in
“Average Count” on page 180 .

higher number of data points, the better the ability to resolve closely spaced
signals and the slower the sweep speed.
How to set number of points
— Press Sweep 3
