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
