Auto Scale Display Button
This command automatically scales each channel on the Anritsu Vector Network Analyzer. It is the same as
using the VectorStar VNA menus to navigate to and select either the
Auto Scale Active Channel
or
Auto Scale
All Channels
buttons. The full path to these buttons is:
• MAIN | Scale | SCALE | Auto Scale Active Channel
• MAIN | Scale | SCALE | Auto Scale All Channels
When the program detects the VNA has finished a sweep, the program auto-scales all four channels before
continuing.
The VNA display during the calibration and verification tests is set to one Channel and four traces. Each trace
displays the following parameters:
• Upper-left quadrant – S21 – Forward Transmissions, Log Mag (top) and Phase (Bottom)
• Upper-right quadrant – S12 – Reverse Transmissions, Log Mag (top) and Phase (Bottom)
• Lower-left quadrant – S11 – Forward Reflections, Lin Mag (top) and Phase (Bottom)
• Lower-right quadrant – S22 – Reverse Reflections, Lin Mag (top) and Phase (Bottom)
See Figure 3-36 for a display example. This is a typical display immediately after performing the High Band
calibration. Please note this is for reference only and that the actual data on the VNA display may not be
identical.
