Analyzing the Signal Detail
You have a noisy signal displayed on the oscilloscope and you need to
know more about it. You suspect that the signal contains much more detail
than you can now see in the display.
Looking at a Noisy Signal
The signal appears noisy and you suspect that noise is causing problems in
your circuit. To analyze the noise better, follow these steps:
1) Press the “ACQUIRE” button to see the acquire menu.
2) Press the “Acquisition” option button or turn the “Universal” knob
to select “Peak Detect”.
3) If necessary, press the “DISPLAY” button to see “Display menu”.
Turn the “Universal” knob to adjust waveform intensity and grid
brightness to see the noise more clearly.
4) Peak detect emphasizes noise spikes and glitches in your signal,
especially when the time base is set to a slow setting.
Separating the Signal from Noise
To reduce random noise in the oscilloscope display, follow these steps:
1) Press the “ACQUIRE” button to display the acquire menu.
2) Press the “Acquisition” option button or turn the “Universal” knob
to select “Average”.
