Logarithm Sweep Time Setting
The sweep time sets the delay time between two frequencies step. It is set from 1 to 1000. The
higher value will put longer delay of two frequencies step.
c. After finishing the linear or logarithm sweep setting, the , key or can be used
to select sine, square, triangle, ramp up (FG700F series) or ramp down (FG700F series) output
