Set the Frequency
Click or tap the
Frequency input field to set the frequency with the pop-up numeric
keypad. You can also use the corresponding multipurpose knob to set the value.
Different waveforms have different frequency ranges.
Sine: 2 mHz to 25 MHz
Square: 2 mHz to 15 MHz
Ramp: 2 mHz to 150 kHz
Arb: 2 mHz to 10 MHz
Set the Amplitude
Click or tap the
Amplitude input field to set the amplitude with the pop-up numeric
keypad. You can also use the corresponding multipurpose knob to set the value. The
amplitude range is related to the waveform frequency setting:
• Basic waveform frequency ≤10 MHz: 2 mV to 10 V
• Basic waveform frequency >10 MHz: 2 mV to 5 V
Set the Offset
Click or tap the
Offset input field to set the offset with the pop-up numeric keypad.
You can also use the corresponding multipurpose knob to set the value. The offset
range is related to the amplitude value.
Set the Stating Phase
Click or tap the
Phase input field to set the starting phase with the pop-up numeric
keypad. You can also use the corresponding multipurpose knob to set the value. Its
available range is from 0° to 360°.
14.1.2 To Output Square
In the AFG setting menu as shown in
Figure 14.1
, click or tap the Function drop-
down button to select "Square". At this time, you can set the parameters for the
square waveform. For how to set the frequency, phase, amplitude, and offset, refer to
descriptions in
To Output Sine
. This section only illustrates how to set the duty cycle
for the square waveform.
Square duty cycle is the percentage of time that the square wave is at a high level
over the period of the square wave, as shown in the figure below. The parameter is
valid only when the square wave is selected.
