When you set [
WATERFALL ON OFF
] to ON, the analyzer adds a new trace to the upper
portion of a waterfall display each time a measurement (or an averaged set of
measurements) is completed. Older traces flow toward the bottom of the display
through its lower portion. The value you enter under [
Z-AXIS RANGE
] determines how
many traces will be displayed in the lower portion of the waterfall display.
The analyzer uses a waterfall buffer to store the results of the last N measurements (or
the last N averaged sets of measurements). You specify the value of N under
[
WATERFALL STEPS
]. After you pause a measurement, you can use the waterfall
markers—described later in this chapter—to go back and analyze the traces in the
waterfall buffer.
The Z-axis range
determines how many
traces appear in this
part of the
waterfall display.
