Signal source EN 17.2 Set waveform modulation Click Modulation to enter the modulation menu. Modulation There are two types of modulation, amplitude modulation (AM) and frequency modulation (FM). AM: Modify the amplitude of the original carrier signal according to the amplitude of the modulated signal. FM: Modify the frequency of the original carrier signal according to the frequency of the modulated signal. Shape: Select the waveform of modulated wave, including sine wave, square wave and triangle wave. Frequency: Set the frequency of the modulated wave, ranging from 1Hz to 50KHz. Depth: Sets the amplitude modulation depth. The settable range is 0-120%. Offset:
Set the modulation offset of frequency modulation, that is, the offset between the modulated waveform frequency and the original carrier frequency.The range is 0.1Hz~1KHZ carrier frequency. (Carrier wave is the modulated wave, and the carrier frequency is the frequency of the selected waveform output by the signal generator except noise and DC.) The sum of the modulation offset and carrier frequency must be less than or equal to the sum of the upper limit of carrier frequency and 1KHz. Set frequency, depth and offset: Click on the numeric area to call out the numeric keypad to set the value. 17.3 Set burst Click Burst to access the burst menu.
Click the the digital area of Count to call out the numeric keyboard to set the number of pulses. The settable range is 1~2000000000. When the burst menu is opened, the burst is on. When the burst menu is closed, thee burst is off. Click Burst to open the burst menu. Set count and click Trigger to get the corresponding waveform state.
