type.
3. Press the Frequency softkey to set frequency, press this key repeatedly to set the Period or
Frequency/Period fine, and turn the Multifunctional Knob to set the value.
4. Press the Amplitude softkey to set amplitude, press this key repeatedly to set the High Level (Offset
automatically switches to low level) or Amplitude /High Level fine, and turn the Multifunctional Knob
to set the value.
5. Press the Offset softkey to set offset, press this key repeatedly to set the Low Level (Amplitude
automatically switches to high level) or Offset /Low Level fine, and turn the Multifunctional Knob to set
the value.
6. Press the Duty softkey to set the duty of Square waveform.
7. Press the Symmetry softkey to set the symmetry of Ramp waveform.
8. Press the Impedance to set the output impedance of the waveform generator, the default is 50Ω.
The waveform will output from GEN OUT BNC port.
3.2. Waveform modulation setting
Press the Modulation softkey to enter the modulation menu.
There are two types of modulation, amplitude modulation and frequency modulation.
Amplitude modulation (AM): Modify the amplitude of the original carrier signal according to the
amplitude of the modulated signal.
Frequency modulation (FM): Modify the frequency of the original carrier signal according to the
frequency of the modulation signal.
Waveform: Select the waveform of the modulating wave. Sine wave, square wave and ramp wave can
be selected.
Modulation frequency: Set the frequency of the modulation wave. The range is 1Hz~50KHz.
Modulation depth: Set the modulation depth of AM. The setting range is 0-120.
Modulation deviation: Set the modulation deviation of FM, that is, the deviation between the
waveform frequency after modulation and the original carrier frequency. The range is 0.1Hz~carrier
frequency. (The carrier is the modulated wave, and the carrier frequency refers to the frequency of the
selected waveform excluding noise and DC output by the signal generator.) The sum of the modulation
deviation and the carrier frequency must be less than or equal to the sum of the upper limit of the
carrier frequency and 1KHz.
Set the modulation frequency, deviation, depth:
: Horizontal arrow, turn the Multifunctional Knob to select a digit to change, press the
Multifunctional Knob to confirm, after turning into a vertical arrow, turn the Multifunctional Knob to
set a value.
