Add Noise
To add the internal noise signal to a waveform, use the Output menu.
Quick Tips
■ An internal noise generator (digital) is used to add noise.
■ CH1 and CH2 noise signals are non-correlating.
■ The Output Status (see page 24) is changed from Output Off to Noise when you push the front-panel Channel Output
button to enable the output.
1. Push the front-panel Sine > Continu-
ous button to display the Sine wave-
form screen in this example.
2. Follow the steps described on page 54
to display the Output Menu. To add
noise to a sine waveform, push Noise.
3. The Noise Add submenu is displayed.
Push Noise Add to select On.
4. To adjust the noise level, push Noise
Level. Use the general purpose knob
or the numeric pad to enter the value.
5. This is a waveform before adding
noise.
6. This is a waveform after adding noise.
To avoid overflow by noise addition, the
amplitude of the output signal is auto-
matically halved.
NOTE. When you set Noise Add to On, the amplitude of output signal is reduced to 50%.
