Example 11: To Generate Linear Sweep
How to generate a Sine Sweep Waveform whose frequency starts from 100Hz to
10KHz. Use Internal Trigger Mode, Linear Sweep, and the Sweep is 1s.
Steps:
1. Choose the Sweep Function:
Press Sine, and choose the Sine Waveform as the Sweep Function.
The default setting of the Source is Internal.
2. Set the Frequency, Amplitude and Offset.
(1) Press Freq and choose Freq which will display in reverse color. Input “5”
from the keypad and choose the unit “kHz” to set the Frequency 5kHz.
(2) Press Ampl and choose Ampl which will display in reverse color. Input
“2” from the keypad and choose the unit “Vpp” to set the Amplitude 2Vpp.
(3) Press Offset and choose Offset which will display in reverse color.
Input “0” from the keypad and choose the unit “Vdc” to set the Offset 0Vdc.
You can view the Sweep Waveform parameters in the Graph Mode
3. Set the Sweep Mode.
Press Sweep  Linear and choose Linear . Please notice that the message
shown on the top left side of the screen is “Sweep Type Linear”.
4. Set the Sweep Time
Press SwpTime , use the keypad to enter “1”, choose the unit “s”, setting the
Sweep Time 1s.
5. Set the Start Frequency
Press Start Freq , use the keypad to enter “100”, choose the unit “Hz”, setting
the Start Frequency 100Hz.
6. Set the Stop Frequency
Press Stop Freq , use the keypad to enter “10”, choose the unit “kHz”, setting
the Stop Frequency 10 kHz.
At this time, the Generator generates the specified Sweep waveform whose
frequency starts from 100Hz and stops at 10 kHz. The Waveform is shown in figure
3-12.
