4.8 Setting and Operation of Sweep
WF1967/WF1968 4-80

When [X-Drive] is selected
A signal with the value of -3V to +3V/open corresponding to the sweep is output from the
synchronization/sub-output terminal. The voltage changes linearly in proportion to sweep elapsed
time. The voltage also changes linearly in proportion to sweep elapsed time, even if logarithmic
sweep [Log-OneWay] and [Log-Shuttle] is selected as the sweep function in frequency sweep.
When a signal during sweep is observed with oscilloscope with X-Y display or X-Y recorder, it can
be used as a signal of the X axis.
The following figure shows the relation between a sweep value and each signal. When the stop
value < the starting value, the slope of the sweep X drive output is contrary to the figure.
