Chapter 17 Function/Arbitrary Waveform Generator (MSO7000 Option)  RIGOL 
MSO7000/DS7000 User Guide  17-3                                                                                                                                                                                                            
continuously to select it. Also, you can enable the touch screen to select it. 
Rotate the multifunction knob    or use the pop-up numeric keypad to set the 
offset or low level value of the current signal. When Impedance is set to "HighZ", 
the available range is from (-2.5 V+currently set amplitude value/2) to (2.5 V- 
currently set amplitude value/2); when Impedance is set to "50Ω", the available 
range is from (-1.25 V+currently set amplitude value/2) to (1.25 V- currently set 
amplitude value/2). 
 
4.  Set the start phase 
Press Start Phase, then rotate the multifunction knob    or use the pop-up 
numeric keypad to set the start phase of the current signal. Its available range is 
from 0° to 360°. 
 
5.  Align phase 
Pressing Align Phase will re-configure the two channels to output according to 
the preset frequency and phase. For two signals whose frequencies are the same 
or in multiple relationship, this operation can align their phases. Use the 
oscilloscope to acquire the waveforms of the two channels and stably display the 
waveforms. After switching the channel status, the phase deviation between the 
two waveforms is changed. At this time, press Align Phase, and then the phase 
deviation shown on the oscilloscope will restore to the current phase deviation 
between the two waveforms automatically. 
 
6.  Setting options 
Press Settings to enter the setting options menu. You can set the parameters 
such as modulation, sweep, burst, and impedance. 
⚫  Modulation, sweep, and burst 
For details about modulation, sweep, and burst, refer to descriptions in 
"Modulation", "Sweep", and "Burst".   
Note: When "Pulse", "DC", or "Noise" is selected under Wave, this menu is 
not available. 
 
⚫  Set the impedance 
Press Impedance continuously to set the output impedance of the 
Function/Arbitrary Waveform Generator. It can be set to "HighZ" or "50Ω". 
 
 
To Output Square 
 
Press Wave, rotate the multifunction knob    to select "Square". Press down the 
knob to select it. You can also press Wave continuously or enable the touch screen 
to select it. At this time, you can set the parameters for the square waveform. For 
setting methods, refer to descriptions in "To Output Sine". The duty cycle of the 
square waveform is a fixed value 50%.
