3.2 Output Frequency Sweep Waveform
When selecting frequency sweep mode, the output frequency of function/arbitrary waveform
generator changes in a linear or logarithmic way from starting frequency to stop frequency in
designated frequency sweep time. Trigger source can be internal, external or manual;
it can generate frequency sweep output for sine wave, square wave, ramp wave and arbitrary wave
(except DC). The modulation mode of the two channels is mutually independent. You can configure
same or different modulation mode for channel 1 and 2.
3.2.1 Select Frequency Sweep Start frequency sweep
Press Menu → Sweep to start frequency sweep. After frequency sweep is used, UTG2000B
function/arbitrary waveform generator will output frequency sweep waveform with the current
