Page 65: Marker Search
Measurement Analysis Marker Search Search the Maximum Value Applying a search for the maximum value of a trace will identify the point within the frequency sweep where the measured value is at its highest point. To perform a maximum search using a marker on a trace: 1. - Page 66 Bird VNA Figure 58 Marker Value Search Min When the data format is a Smith chart or Polar coordinate, only the primary response value is searched. Search Target Value Utilize the target search function to relocate the marker to a point along a trace where measurement value yields the closest match to the indicated target value that aligns with the defined target transition type.
- Page 67 Measurement Analysis The operator can choose either positive or negative transitions (or transfers) to search against, or they can opt to search for both. Once a Target Value and Transition is defined, the operator can choose one of the three options in Table 11 search for the value.
- Page 68 Bird VNA Search Peak Use the peak search function to move the marker to the peak on the trace.

Page 72: Search Range
Bird VNA Search Range Use the search range function to perform a focused target search on a partial scan range within the swept frequency range. As needed, the operator may also choose to: Show vertical limit lines indicative of the search range boundary. -
Page 73: Marker Function
Measurement Analysis Marker Function Marker Transfer Setting Use the Marker value to set the scan range. A convenient way of adjusting stimulus settings is through the use of marker locations. When adjusting the start stimulus point for the scan, the stop point will remain the same and the position of the selected marker will be used as the new start stimulus point. - Page 74 Bird VNA When adjusting the scan using the center point option, the start point will remain the same and the difference between the selected marker position and the start point will be doubled and used as the new stimulus span with the stop point set to the end.
- Page 75 Measurement Analysis The value of the markers is measured based on group delay, which is applicable when the format of the trace containing the marker is set to Group Delay. If the reference marker is enabled and the value of the working marker is relative, the value of the reference marker dictates that the transfer setting value will be utilized in absolute terms.

Page 78: Limit Test
Bird VNA Limit Test The use of limit testing allows an operator to apply immediate measurement evaluation with on-screen visualization to be set for each trace as well as a pass / fail status of the limit test result. Pass / Fail status is determined by how a limit is defined in the limit table. Multiple limit entries can be added to the table as needed and are categorized by type, inspection frequency range, and the levels against which the limit test is to be judged. - Page 79 Measurement Analysis Limit Table Editing The general process for limit table editing, including add, delete, modify, clear, save, restore and other operations are defined as follows.

Page 95: Chapter 9 Measurement Optimization
Chapter 9 Measurement Optimization Expand the Dynamic Range The dynamic range is the finite difference between the maximum input power level of the analyzer and the minimum measured power level (background noise). It is important to increase the dynamic range when evaluating a characteristic accompanied by a large change in amplitude (e.g., passband or stopband for a filter). -
Page 96: Reduce Trace Noise
Bird VNA Reduce Trace Noise Smoothing in the analyzer averages neighboring trace points using a moving window, with the window size as a percentage of total trace points. It doesn't extend measurement time or increase the dynamic range. Smoothing reduces noise bursts and is applied separately to each trace. For improved trace representation, mathematical smoothing calculates the moving average of nearby points. -
