Shuttle sweep
Sweep value
g) To change the rising/falling direction of the sweep →Magnitude relation of start and
stop values
When sweeping is done with a sawtooth wave (one-way sweep), sweeping is done from the
start value to the stop value. If start value < stop value, the value increases during sweep
execution. Reversely, if start value > stop value, the value decreases during sweep execution.
When the [Stt Stp] soft key included in the second stage of the soft key set on the 2nd page of
the setting screen ([▼2/2] is displayed on the right-most soft key) is pressed, the start value and stop
value can be swapped.
h) To continuously repeat sweep →Continuous sweep
Set [SwpMode] (sweep mode) on the 2nd page of the setting screen to [Cont] (continuous).
No trigger signal is required.
The transition time from the start value to the stop value is set with [Time] (sweep time) on the 2nd
page.
