Chapter 17 Function/Arbitrary Waveform Generator (Option) RIGOL
DS8000-R User Guide 17-15
⚫ Set start frequency and end frequency
Start frequency and end frequency indicate the upper and lower limits of
the sweep frequency. The Function/Arbitrary Waveform Generator always
sweeps from the start frequency to the end frequency, and then returns
back to the start frequency.
➢ When start frequency is smaller than the end frequency, the
Function/Arbitrary Waveform Generator sweeps from low frequency to
high frequency.
➢ When start frequency is greater than the end frequency, the
Function/Arbitrary Waveform Generator sweeps from high frequency
to low frequency.
➢ When start frequency is equal to the end frequency, the
Function/Arbitrary Waveform Generator outputs at a fixed frequency.
Click Start Freq, then use the pop-up numeric keypad or scroll with the
mouse to set the start frequency. Click End Freq, then use the pop-up
numeric keypad or scroll with the mouse to set the end frequency. By
default, the start frequency is 100 Hz, and the end frequency is 1 kHz. The
ranges of start frequency and end frequency for different sweep waveforms
are different. After modifying the "Start Freq" and "End Freq", the
Function/Arbitrary Waveform Generator will restart to output from the
specified "Start Freq".
⚫ Start Keep
Start keep indicates the time that the output signal keeps outputting at the
"Start Freq" after the sweep starts. After the start keep time expires, the
Function/Arbitrary Waveform Generator will continue outputting at a
different frequency based on the current sweep type.
Click Start Keep, then use the pop-up numeric keypad or scroll with the
mouse to set the start keep time. The default is 0 s, and the range is from 0
s to 500 s.
⚫ End Keep
End keep indicates the time that the output signal continues outputting at
the "End Freq" after the Function/Arbitrary Waveform Generator sweeps
from "Start Freq" to "End Freq".
Click End Keep, then use the pop-up numeric keypad or scroll with the
mouse to set the end keep time. The default is 0 s, and the range is from 0
s to 500 s.
⚫ Set the step
When the sweep type is set to "Step", this menu is enabled and can be
settable. Click Step number, then use the pop-up numeric keypad or scroll
with the mouse to set the step value. By default, it is 2. Its available range
