Example 11: To generate a Linear Sweep
How to generate a Sine Sweep Waveform whose frequency starts from 100Hz to
10kHz. Use the Internal Trigger Mode, Linear Sweep, and the Sweep time is 1s.
The operation 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 Period/Freq and choose Freq which will display in reverse color.
Enter “5” from the keypad and choose the unit “kHz” to set the Frequency as
5 kHz.
(2)
Press Ampl/HiLev and choose Ampl which will display in reverse color.
Enter “2” from the keypad and choose the unit “V
pp
” to set the Amplitude as
2 V
pp
.
(3)
Press Offset/LoLev and choose Offset which will be displayed in
reverse color. Enter “0” from the keypad and choose the unit “V
dc
” to set the
Offset as 0 V
dc
.
You can view the Sweep Waveform in the Graph Mode.
3.
Set the Sweep Mode.
Press Mod
Æ
Linear/Log and choose Linear. Please notice that the message
shown on the top left side of the screen is “Linear”.
4.
Set the Sweep Time
Press Time , use the keypad to enter “1”, choose the unit “s”, to set the Sweep
Time as 1s.
5.
Set the Start Frequency

Frequency as 100Hz.
6.
Set the Stop Frequency
Press Stop , use the keypad to enter “10”, choose the unit “kHz”, to set the Stop
Frequency as 10 kHz.
At this time, the instrument generates the specified Sweep waveform whose
