Fig. 8-1: Waveform mask with horizontal width = 0.2 div
SCPI command:
MTESt:WFMRescale:XWIDth on page 606
Vertical width
Sets the width of the waveform mask in vertical direction. The specified number of divi-
sions is added to the y-values of the upper mask limit and subtracted from the y-values
of the lower mask limit. Thus, the upper half of the mask is pulled upwards, the lower half
is pulled down, and the overall height of the mask is twice the vertical width.
Fig. 8-2: Waveform mask with vertical width = 0.5 div
SCPI command:
MTESt:WFMRescale:YWIDth on page 606
Vertical stretch
Sets the vertical scaling to stretch the mask in y-direction. The scaling axis is the hori-
zontal line through the lowest value of the lower mask limit. Values > 100% stretch the
mask, and values < 100% compress it.
