4.3 Result Evaluation
In spot measurements, it is possible to automatically evaluate whether the gain (dB) and
phase measured values fit within a specified range and to display the results.
Result evaluation cannot be performed on gain (linear) or complex gain a+jb.
4.3.1 Evaluation Range Setting
To execute the result evaluation, set the following setup items under the spot menu
screen.
If minimum value
≧
maximum value the evaluation will not be executed.
■
Result evaluation Gain maximum value SPOT GO/NG G max
■
Result evaluation Gain minimum value SPOT GO/NG G min
Value range:
-
199.99 to +199.99 dB, resolution 0.01 dB
■
Result evaluation Phase maximum value SPOT GO/NG P max
■
Result evaluation Phase minimum value SPOT GO/NG P min
Value range:
-
360.00 to +360.00 deg, resolution 0.01 deg
4.3.2 Evaluation Display
Evaluation results are displayed on the spot measurement screen.
▲
: OVER is displayed when measured value
＞
maximum value.
▼
: UNDER is displayed when measured value
＜
minimum value.
▲▼
neither of both is displayed when minimum value
≦
measured value
≦
maximum value.
When the evaluation result is either OVER or UNDER, the item name is displayed in red.
