Chapter 17 Function/Arbitrary Waveform Generator (Option) RIGOL
DS8000-R User Guide 17-15
âš« 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".
âš« 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.
âš« 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.
âš« 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
