RIGOL Chapter 17 Function/Arbitrary Waveform Generator (Option)
17-4 DS8000-R User Guide
Click Settings → Symmetry, then use the pop-up numeric keypad or scroll with
the mouse to set the symmetry of the ramp waveform. The settable range is from
1% to 100%.
To Output Pulse
Click Wave to select "Pulse". At this time, you can set the parameters for the pulse
waveform. For setting methods, refer to descriptions in "To Output Sine". This
section only introduces "Duty Cycle".
Duty cycle is defined as the percentage that the high level takes up in the whole
pulse period, as shown in the figure below.
T
t
Duty Cycle=t/T*100%
Figure 17-2 Duty Cycle Definition
Click Settings → Duty Cycle, then use the pop-up numeric keypad or scroll with
the mouse to set the duty cycle of the current pulse signal. Its settable range is from
2% to 98%.
To Output DC
Click Wave to select "DC". At this time, you can set the offset and impedance of the
DC signal.
1. Set the offset
Click Offset, then use the pop-up numeric keypad or scroll with the mouse to
set the offset value of the current DC signal. When the current impedance is set
to HighZ, the settable range of offset is from -2.5 V to +2.5 V; when the
impedance is set to 50 Ω, the settable range of offset is from -1.25 V to +1.25 V.
2. Set the impedance
Click Impedance continuously to set the output impedance of the
Function/Arbitrary Waveform Generator. It can be set to "HighZ" or "50Ω".
