<VAL3>:
Responds with a text report that summarized the grading of ISO/IEC15415.
This command will return the evaluation results, in a format similar to the one shown below.
I-6-8 Grid Non-Uniformity
Definition:
Grid Non-Uniformity is calculated in accordance with the ISO 15415
specification. The Grid Non-Uniformity grading is defined as follows.
A (4.0) if GN ≤ 038
B (3.0) if GN ≤ 0.50
C (2.0) if GN ≤ 0.63
D (1.0) if GN ≤ 0.75
F (0.0) if GN > 0.75
When enabled, the Grid Non-Uniformity is attached to the symbol out-
put data as a value.
