DDS-3X25 USB Waveform Output Control By the following buttons to control the output dot numbers, trigger mode, output amplitude, and limit frequency of the wave filter. Single Wave: Output waveform only once. -20dB : Attenuation the waveform Ext Trig: Use the external or internal trigger system. Wave ON/OFF: Turn the waveform on/off. Ext Trig Mode: External Trigger Mode (see “External Trigger Input”). Phase: The phase of the waveform to generate. Y Offset: The offset of the waveform to generate. Frequency: The frequency of the waveform to generate (The Frequency Range is DC~75MHz when generating sine waveform, or DC~25MHz when generating other waveforms). Amplitude:
The maximum voltage of the waveform to generate. DDS-3X25 USB User’s Guide 21
