Applications (contd.)
7. Generate a Sweep
Linear Wave
Generate a sine sweep waveform whose frequency starts from 100Hz to
10kHz. Use internal trigger mode, linear sweep, and the sweep time is 2s.
Steps:
Set the sweep function:
Press Sine, and choose the sine waveform as the sweep function.
The default setting of the source is internal.
Set the frequency, amplitude and offset.
1. Press Freq and choose Freq which will display in white color. Input
“5” from the keyboard and choose the unit “KHz” to set the frequency
5 kHz.
2. Press Ampl to choose Ampl which will display in white color. Input “5”
from the keyboard and choose the unit “Vpp” to set the amplitude 5
Vpp.
3. Press Offset to choose Offset which will display in white color. Input
“0” from the keyboard and choose the unit “Vdc” to set the offset
0Vdc
Set the sweep time.
Press Sweep
→
Sweep Time , Input “2” from the keyboard and
choose the unit “s” to set sweep time 2s.
Set the start frequency
Press Start Freq, Input “100” from the keyboard and choose the unit
“Hz” to set start freq 100Hz.
Set the end frequency
Press End Freq, Input “10” from the keyboard and choose the unit
“kHz” to set stop freq 10 kHz.
Set the Sweep Mode
Press (1/2
