Vector Network Analyzer MG PN: 10580-00289 Rev. K 2-1
Chapter 2 — VNA Display Overview
2-1 Introduction
This chapter provides an overview of the display features that are found in the VNA Master
and the S412E LMR Master. The topics include active traces, trace format, number of traces,
markers, and limits.
2-2 Powerful Display Capabilities
These vector network analyzers have a flexible display capable of single, dual, tri, and quad
displays, meaning that you can subdivide the measurement display area into 2, 3, or
4 sections. In addition, the vector network analyzers support the display of up to four traces
in each single, dual, tri, or quad display. Becoming familiar with these flexible display
capabilities is important before you begin any calibrations and measurements.
The function hard keys in Vector Network Analyzer mode without Option 2 (Time Domain)
are:
Freq/Dist, Scale, Sweep, Measure, Marker
The function hard keys in Vector Network Analyzer mode with Option 2 (Time Domain) are:
Freq/Time/Dist, Scale, Sweep, Measure, Marker
Flexible Features For Displaying Results
If you are not yet familiar with the menus that control trace display, refer to the “Measure
Menu” on page 6-46, to the “Number of Traces Menu” on page 6-51, and to the “Trace Format
Menu” on page 6-52. To select the Measure soft key menu on your vector network analyzer,
press the Measure function hard key (you must be in Vector Network Analyzer mode for this
example).
Perform the following steps to observe the trace format features:
1. In MS20xxC instruments, the default view uses Trace Format = Quad with Number of
Traces = 4. Refer to Figure 2-1 on page 2-4.
In MS20xxB and S412E instruments, the default view uses Trace Format = Dual with
Number of Traces = 2.
2. Beginning with the default view, set Trace Format = Single, and Number of Traces = 4.
Notice how all 4 traces are overlaid on a single graph. Refer to Figure 2-2 on page 2-4.
3. Next, set Trace Format = Dual. Note how the 4 traces are assigned to the split display.
TR1 (Trace 1) and TR3 are assigned to the top graph. TR2 and TR4 are assigned to the
bottom graph. Refer to Figure 2-3 on page 2-5.
4. Next change Trace Format to Tri. Note how the 4 traces are assigned on this display.
TR3 and TR4 are now overlaid in the bottom half of the display area. Refer to
Figure 2-4 on page 2-5.
