Using the Average Detector and
Increased Sweep Time
When the analyzer’s noise masks low- level signals,
changing to the average detector and increasing the
sweep time smooths the noise and improves the
signal’s visibility. Slower sweeps are required to
average more noise variations.
1 Refer to
“Reducing Input Attenuation" on
page 49, and follow steps 1, 2 and 3.
2 Press [TRACE] > {More (1 of 2)} > {Detector} >
{Average} to select the average detector.
3 Press [BW/SWP] > {Sweep Time} to set the sweep
time to 500 ms.
Note how the noise smooths out, as there is
more time to average the values for each of the
displayed data points.
4 Press [BW/SWP] > {Avg Type} to change the
average type.
