VNA Display Overview
2-2 Powerful Display Capabilities
Another powerful feature to become acquainted with is the ability to Maximize and Minimize
an active trace. On the quad default display, select Maximize Active Trace from the Measure
menu, and note how this feature zooms in on the active trace and uses maximum area to
display the measurement results. Next, select Minimize Active Trace to return to the original
trace format of quad display. On instruments with touch screen, touching an active trace
twice in rapid succession alternately maximizes and minimizes that trace. Note that this
touch ability is disabled when the marker menu is active because of the touch and drag ability
for markers.
Combining the previously described active trace selection techniques with this Maximize and
Minimize active trace feature allows for maximum flexibility in extracting the measurement
results from the display.
Touch Screen Trace Features
These touch features differ when the Marker menu is displayed (refer to
"Markers on a Touch
Screen" on page
2-8).
Selecting a Trace
In VNA Measurements view on touch screen instruments, when Trace Format is Dual, Tri, or
Quad, you can touch or tap either the trace itself or the trace data in the Instrument Settings
Summary (left edge of sweep window) to select a trace.
These touch points function in the same manner when using the Field Measurements view in
Display Type Dual.
In Display Type Overlay, however, only a touch on trace data for TR2 in the Instrument
Settings Summary selects Trace 2 as the active trace. Any touch on the sweep window selects
Trace 1 (the upper or top trace) as the active trace.
If a Marker is active on a trace, and if the Marker menu is displayed, then after that trace is
active, an additional touch within the sweep window affects the location of the active marker
(refer to
"Markers on a Touch Screen" on page
2-8).
Maximizing and Minimizing Traces
In VNA Measurements view, when a trace is active in Dual, Tri, or Quad format, a quick
double tap on either the trace itself or the trace data in the Instrument Settings Summary
maximizes the active trace. Another double tap minimizes the trace. When a trace is
maximized, touching a different trace in the Instrument Settings Summary displays that
touched trace in maximized view. These touch points are not functional when using the Field
Measurements view,
This touch feature differs when a Marker is active on a trace and the Marker menu is
displayed.
Trace Description
A trace is a measurement result that can have user-defined attributes assigned to it for
display purposes. You can assign the following attributes for a trace: S-parameter, Graph
Type, Domain, and Smoothing. Using the Scale menu, you can independently set the scale for
each trace.
