Noise Figure Mode (Option 356 – CPU2 Only)
How to Define a Noise Figure Measurement
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 noise figure (NF) to make continuous sweeps. This 
is the typical setting for making measurements. Each Run / 
Hold +/- press causes NF to toggle between continuous sweep 
and Hold. 
——OFF
 Causes NF to Hold. Each Run / Hold +/- or Single press 
causes NF to make ONE sweep, then Hold. The Hold 
annotation changes to an arrow --> while the sweep occurs.
—Single
 Automatically sets Continuous OFF and causes NF to make 
ONE sweep, then Hold.
—Restart
 Resets the sweep to the current defined start frequency point.
Points 
Points is the number of measurements that are measured and displayed along 
the X-axis. The 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 
—Then Points [current setting] 
— Then choose from: 03 | 05 | 11 | 21 | 51 | 101 | 201 | 401 | 601 | 801 | 1001
