The X-scaling Control Fields
The X-scaling control fields control the scaling of the X-axis. Precisely how the fields
are used depends on what is being displayed. In the following, a general description of
the X-scaling fields is given first for time domain functions and then for frequency
domain functions, followed by exceptions to these general descriptions.
a) Time Domain Functions
Two X-scaling control fields are used when time domain functions are displayed. They
control the start of the time function and the displayed time span. The time function
can be expanded on the Display by using the time span field to reduce the displayed
time span and the start field to scan the displayed portion back and forth across the
whole time domain function.
