Setting Sweeps
IM 707281-01E
Selecting the parameter to sweep
Select which parameter to sweep from the following list of choices.
Off : Do not sweep
Freq : Sweep the frequency
Ampl : Sweep the amplitude
Duty : Sweep the duty cycle (selectable only for pulse waveform)
Freq & Ampl : Sweep the frequency and amplitude
Selecting the sweep pattern
Select how to sweep the parameter from the following list of choices.
Linear: Sweep linearly
Log: Sweep logarithmically
Arbitrary: Sweep using an arbitrary pattern
Loading the sweep pattern
When the sweep pattern is set to [Arbitrary], an arbitrary pattern is loaded.
You can load the following files containing data of length 64 Kwords.
• wvf file (a corresponding header file with file extension [.hdr] is also needed, see page
1-13)
• ASCII data in csv format (see page 1-13)
Note
• If the data length of the file being loaded is greater than 64 Kwords, the first 64 Kwords of data
are loaded. If it is shorter, data after the last data point are filled with the value of the last data
point.
• When an arbitrary pattern is loaded, the minimum and maximum values of the data correspond
to the values in the [.... Start] and [.... End] boxes of the parameter to be swept, respectively.
