Analyzing Signal Detail; Looking At A Noisy Signal - Tektronix TPS2000 Series User Manual

Analyzing 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 better analyze the noise, follow these
steps:
1. Push the ACQUIRE button to see the Acquire Menu.
2. Push the Peak Detect option button.
3. If necessary, push the DISPLAY button to see the Display Menu.
Use the Adjust Contrast and the Adjust Brightness option
buttons with the multipurpose knob to adjust the display to see
the noise more easily.
Peak detect emphasizes noise spikes and glitches in your signal,
especially when the time base is set to a slow setting.
