UTG1000A Series 23
Carrier Wave Frequency Setting
Settable carrier wave frequency range is different for different carrier waveforms. Default frequency of all carrier
wave is 1kHz. The frequency setting range of each carrier wave can be seen in the following table:
Carrier Wave

If need to set carrier frequency, please press Parameter → Frequencysoftkey, then enter required numerical value,
and select unit after selecting carrier waveform.
Modulation Source Selection
This device can select internal modulation source or external modulation source. After enabling AM function, the
default modulation source is internal. If need to change press Parameter
→ ModulationSource → External in turn.
1) Internal Source
When modulation source is internal, modulation wave can be: sine wave, square wave, rising ramp wave, falling
ramp wave, arbitrary wave and noise. After enabling AM function, the default of modulation wave is sine wave. If
need to change it, press Carrier Wave
→ Parameter → Type in turn.

Square wave: duty cycle is 50%

Rising Ramp Wave: symmetry degree is 100%
 Falling Ramp Wave: symmetry degree is 0%

Arbitrary Wave: when arbitrary wave is modulated waveform, DDS function generator limits
arbitrary wave length as 1kpts in the way of random selection

Noise: White Gauss noise
