Frequency Amplitude Add Point |
Add Vertical In many measurement masks, step changes occur in the value of the limit line. Press this submenu key to add two inflection points. The two inflection points share the same frequency and are centered midpoint between adjacent measured points. The magnitudes of the points are set by using a visually intuitive algorithm that is based upon the adjacent inflection points. You can adjust the magnitudes independently, but the frequencies of the two points remain linked and are adjusted as a vertical pair. Setting a discrete frequency, a limit inflection point keeps that exact frequency and place the limit point appropriately regardless of the frequency span. This is especially useful for emission mask verification. Delete Point Press this submenu key to delete the currently active point. The active point becomes the point that is immediately to the left of the point that was deleted. Next Point Left Press this submenu key to select the inflection point that is immediately to the left of the active point, making this newly selected point active for editing or deletion. With each key press, the active point becomes that point to the left of the previously active point, until the newly selected active point becomes the left‑most point on the screen. Next Point Right Press this submenu key to select the limit point immediately to the right of the active point, making this newly selected point active for editing or deletion. With each key press, the active point becomes that point to the right of the previously active point, until the newly selected active point becomes the right‑most point on the screen. Back Press this submenu key to return to the Limit Menu. |
