5. Set the start phase
Press Start to set the start phase of the signal. The range is from 0°to 360°.
For the setting method, please refer to the introduction in
“ Parameter Setting
Method”.
6. Align Phase
Pressing Align will re-configure the two channels (Source 1 and Source 2) to
output according to the preset frequency and phase. For two signals of which the
frequencies are the same or are multiples, this operation can align their phase.
Acquire the waveforms of the two channels using the oscilloscope and display
the waveforms stably. After switching the channel status, the phase deviation
between the two waveforms is changed. At this point, press Align and the phase
deviation shown on the oscilloscope will restore to the current phase deviation
between the two waveforms automatically.
7. Modulation
Press Modulation to turn on or off the modulation function. For the detailed
introduction of the modulation function, please refer to “
Modulation”.
8. Set the impedance
Press Impedance to set the output impedance of the signal generator. It can be
set to “HighZ” or “50Ω”.
To Output Square
Press Setup1 to open the waveform setting menu. Press Wave and select “Square”.
At this point, you can set the square parameters. For the detailed setting method,
refer to the introduction in “
To Output Sine”. The duty cycle of square is fixed at
50%.
