  • Page 30: Synchronized Output

    DDS-3025 USB 3.8 Synchronized output If you generate a waveform by software, there is a synchronized signal output from “SYNC” terminal. The signal is square waveform, the frequency of which is equal to the waveform you generated. For example, if you generated a 1 KHz, sine waveform, you will also generate an 1 KHz, square waveform simultaneously.

  • Page 31: External Trigger Input

    DDS-3025 USB 3.9 External Trigger Input Also, you can use the external trigger input to control the DDS-3025USB. For example, the instrument generated a waveform, and you got a waveform on oscilloscope. Then, click the “Ext Trig” button on the interface of the software. The waveform on the oscillograph disappeared.
  • Page 32 Click the “Ext Trig” mode to switch the external trigger mode between “Fall” and “Rise”. Select the Fall mode as example. Input a signal which has fall edges to the “TRIGIN” BNC terminal. When the DDS-3025USB gets to the fall edge of the external signal, it begins to generate waveform.
