Analyzing Data > Analysis Settings Analysis Time Tab
Setting Description
Analysis Offset Speci fi es the location of the fi rst time sample to use in measurements.
Auto When enabled, causes the instrument to set the Analysis Offset value based on the
requirements of the selected display.
Analysis Length Speci fi es the length of time to use in measurements.
Auto When enabled, causes the instrument to set the Analysis Length value based on the
requirements of the selected display.
Time Zero Reference Speci fi es the zero point for the analysis time.
Actual This is a displayed value, not a setting. It is the Analysis Length (time) being used by the
analyzer; this value may not match the Analysis Length requested (in manual mode).

Analysis Offset
Use analysis offset to specify where measurements begin. Range: 0 to [(end of acquisition) - Analysis
Length)]. Resolution: 1 effective sample (or symbol).
Analysis Length
Use the analysis length to specify how long a period of time is analyzed by a measurement. After you
enter a value, this box changes to show the actual value in use, which is constrained by Acquisition Time.
This setting is not available when Auto is checked. Range: minimum value depends on modulation type
to Acquisition Length. Resolution: 1 effective sample (or symbol).
Time Zero Reference
The analysis offset is measured from this point. Choices are: Acquisition Start or Trigger Point.
Parameter Description
Acquisition Start Offset is measured from the point at which acquisition begins.
Trigger Point Offset is measured from the trigger point.
