How To Set The Parameters Of Pwm; To Generate Sweep - PeakTech 4125 Bedienungsanleitung

5.34. How to set the parameters of PWM (only PeakTech
1. Press Mod function button, then press F1 to select Mod.
2. Press F1 to switch Mod Type to PWM. If the Carrier Waveform is not Pulse, the
system will switch it to Pulse automatically.
3. Press button to display the waveform and parameters of the Carrier Waveform.
You can change the parameters, please refer to "To Output Sine Signals" on page 67.
Press button again to return to the Modulation mode interface.
4. Press F5 to select the source. If the source is External, use the Modulation In
connector in the rear panel to input the external signal, then skip ahead to step (6). If
you choose Internal, continue to the steps below.
5. Press F2 to choose Mod Shape, you can choose Sine, Square or Ramp.
6. Press F3 to set Mod Frequency. The range is 2 mHz～20 kHz (Internal source
only).
7. Press F4 to set Width Deviation/Duty Deviation (depends on the P_Width/Duty
menu item of the Pulse setting menu when you exit the Modulation mode). The
maximum range of the Duty Deviation is the smaller one in [Pulse Duty, 1-Pulse Duty].
The maximum range of the Width Deviation is Pulse Width.

5.35. To Generate Sweep

Sweep function is only used for CH1. In the frequency sweep mode, the generator "steps"
from the start frequency to the stop frequency at the sweep rate you specify. Sweep can
be generated by Sine, Square or Ramp Waveforms.
