X and Y
Position
The Position softkeys allow you to use the histogram markers to select a
region of the database. X1 and X2 position move the vertical histogram
markers vertically across the display, while Y1 and Y2 position move the
horizontal histogram markers horizontally across the display. Because the
database that the histogram is derived from is limited to the size of the
graticule area, placing the histogram markers beyond the graticule area
results in a histogram of only the graticule area.
For manual jitter measurements, you would position the Y1 and Y2 histogram
markers so that the histogram is built from a very narrow horizontal slice
of the graticule area. For noise measurements, you would position the X1
and X2 histogram markers so that the histogram is built from a very narrow
vertical
slice
of
the
graticule
area.
