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
display is a paired
Log Mag
(top) and
Phase
(bottom) display showing the following parameters:
•
Upper-left quadrant – S21 – Forward Transmission
•
Upper-right quadrant – S12 – Reverse Transmission
•
Lower-left quadrant – S11 – Forward Reflection
•
Lower-right quadrant – S22 – Reverse Reflection
See
below 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.
