Setting the frequency range and the number of points

Operation
Step 1. Press
NOTE
The frequency range and the number of points are common to all of the traces in the
channel. If you want to use different settings, make them on another channel.
Step 2.
NOTE When the sweep type is set to other than the "linear sweep," the time domain function is
not available.
Step 3. Use the following keys to set the sweep range.
