The following steps show you how to use the oscilloscope to capture a
single event.
1. Set the Probe option attenuation to 10X and set the switch to 10X
on the probe.
2. Trigger set up:
1) Press “TRIG MENU” button to show the “Trigger Menu”
2) Under this menu, set the trigger type to “edge”, Edge type
is “Rising”, source is “CH1”, trigger mode is “Single”,
coupling is “DC”
3) Adjust the horizontal time base and vertical scale to the
satisfied range
4) Turn the “LEVEL” knob to adjust the trigger level
5) Press the “RUN/STOP” button to start capturing
When the trigger conditions are satisfied, data appears on the display
representing; the data points that the oscilloscope obtained with one
acquisition and press the RUN/STOP button again rearms the trigger circuit
and erases the display.
Analyzing Signal Details
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.
