Sweep Mode
Touching the Sweep Mode button, a menu opens that gives the possibility to choose a sweep profile
among the following:
•
Linear:
the frequency increases and decreases linearly.
•
Logarithm:
the frequency increases and decreases following a logarithmic function.
•
Upstair:
the frequency varies step by step. The number of steps is selectable through the
Step
Number
parameter.
•
User Defined:
allows to load a sweep profile from a file. For the file specification please refer to
the “Import from File” section. By default, the “Arbitrary” waveform is a cosine function.
Note:
the time to execute the sweep is the sum of Rise, Hold and Return Time. When the User
Defined mode is selected these 3 parameters are not meaningful.
Parameters
•
Rise Time [s]:
controls the time to increase the frequency from the Start Frequency up to the
Stop Frequency.
•
Hold Time [s]:
defines the time that the frequency keeps the Stop Frequency.
