• Two variants of AVERAGING menus are available, determined by whether the sweep type is frequency- or power-based, or is segment-based.
• If a frequency/power-based sweep is used, the menu has seven (7) buttons.
• If a segment-based sweep is used, the menu has five (5) buttons. For segment-based sweeps, Averaging, IFBW, and Power settings are made on a per-segment basis on the segment-based setup tableaus at the bottom of the screen. (See Segmented Frequency-Based Sweep Setup and Segmented Index-Based Sweep Setup.)
5. Smoothing % (Smoothing Percentage) Field Toolbar
6. AVERAGING Menu – Example of frequency-/power-based sweeps menu with parameters set and Averaging OFF.
7. AVERAGING Menu – Example of frequency-/power-based sweeps menu with parameters set and results shown with Averaging ON. When set to ON, the Reset Avg Count and a similar display in the channel status bar count up to the Averaging Factor value setting.
Averaging (Off/On)
Button present for frequency-based and power-based sweeps. Select toggles trace averaging off and on.
Sweep By Sweep Averaging
Sweep-by-sweep averaging aggregates data on a sweep basis, hence represents averaging with a longer sampling time between data elements. In the case of segmented sweep, the sweep-by-sweep averaging is global for all segments (unlike point-by-point averaging which can be assigned per segment).
Sweep By Sweep Avg. (Off/On)
Button present for segmented-based sweeps. When toggled ON, the status bar displays Averaging status:
When Sweep By Sweep Avg. is toggled OFF, the status bar displays Averaging status as NA. If sweep by sweep The status bar will continue to say Avg N/A since point by point averaging could be set per segment:
Averaging Factor
Button only present for frequency-based and power-based sweeps. Not present for segment-based sweeps. Select displays the Averaging Factor field toolbar.
Averaging Type (Per Point/Per Sweep)
Button only present for frequency-based and power-based sweeps. Not present for segment-based sweeps. Select toggles between averaging per point and averaging per sweep.
Reset Average Count
Button present for frequency-based, power-based, and segment-based sweeps. Read only display field. Counts up to the Averaging Factory value as the averaging session proceeds. Select resets the averaging count to 0 (zero), and the averaging session starts anew.
IFBW
Button only present for frequency-based and power-based sweeps. Not present for segment-based sweeps. Select displays the IFBW field toolbar for setting the Intermediate Frequency Bandwidth frequency. The toolbar allows discrete values of:
• 1 Hz, 2 Hz, 3 Hz, 5 Hz, 7 Hz
• 10 Hz, 20 Hz, 30 Hz, 50 Hz, 70 Hz
• 100 Hz, 200 Hz, 300 Hz, 500 Hz, 700 Hz
• 1 kHz, 2 kHz, 3 kHz, 5 kHz, 7 kHz
• 10 kHz, 20 kHz, 30 kHz, 50 kHz, 70 kHz
• 100 kHz, 200 kHz, 300 kHz, 500 kHz, 700 kHz
• 1 MHz
Units of MHz, kHz, or Hz can be selected.
Trace Smoothing (Off/On)
On a per-trace basis, toggles trace smoothing OFF and ON.
Smoothing
On a per-trace basis, select displays the Smoothing % field toolbar. The toolbar allows the user to set the percentage of trace smoothing in use. A display below the button field shows the number of points that are smoothed.
