Configuring the Display Scale
Depending on the measurement parameter data format, you can configure the display scale
in one of the following two ways:
Rectangular display formats:
When you are using one of rectangular display formats (Logarithmic magnitude/Phase/
Group delay/Linear magnitude/SWR/Real/Imaginary/Expanded phase/Positive phase), you
can configure the display scale by setting the following four items:
NOTE The number of divisions is a channel-wide setting (shared among all traces) while the
remaining three settings are trace-specific.
You can show or hide graticule label (the label on the left-hand side of the graticule lines)
by issuing the following command:
:DISP:WIND{1-4}:LAB on page 321
Smith Chart/Polar formats:
When you are using one of Smith chart/Polar formats, you can only set the full scale value
(the outermost circle's value) using the following command:
:DISP:WIND{1-4}:TRAC{1-4}:Y:PDIV on page 330
Auto Scale
You can use Auto Scale to automatically set the display scale. This feature works by
automatically adjusting the reference division line value and the scale value per division
when you are using one of rectangular display formats; or the full scale value when you are
using one of Smith chart/Polar formats.
To perform Auto Scale, use the following command:
:DISP:WIND{1-4}:TRAC{1-4}:Y:AUTO on page 329
Number of divisions :DISP:WIND{1-4}:Y:DIV on page 336
Scale per division :DISP:WIND{1-4}:TRAC{1-4}:Y:PDIV on page 330
Reference graticule line :DISP:WIND{1-4}:TRAC{1-4}:Y:RPOS on page 332
Reference graticule line value :DISP:WIND{1-4}:TRAC{1-4}:Y:RLEV on page 331
