Digital Storage Oscilloscope 60
The real-time acquisition has four modes: Normal, Peak Detect, Average and High
Resolution. The acquisition rate is affected by the setting of time base.
Normal: In this acquisition mode, the oscilloscope samples the signal in evenly spaced
intervals to establish the waveform. This mode accurately represents signals in most
time. However, it does not acquire rapid variations in the analog signal that may occur
between two samples, which can result in aliasing and may cause narrow pulses to be
missed. In such cases, you should use the Peak Detect mode to acquire data.
Peak Detect: In this acquisition mode, the oscilloscope gets the maximum and
minimum values of the input signal over each sample interval and uses these values to
display the waveform. In this way, the oscilloscope can acquire and display those
narrow pulses that may have otherwise been missed in Normal mode. However, noise
will appear to be higher in this mode.
Average: In this acquisition mode, the oscilloscope acquires several waveforms,
averages them, and displays the resulting waveform. You can use this mode to reduce
random noise.
High Resolution(HR): This mode uses a kind of ultra-sample technique to average the
neighboring points of the sample waveform to reduce the random noise on the input
signal and generate much smoother waveforms on the screen. This is generally used
when the sample rate of the digital converter is higher than the storage rate of the
acquisition memory.
Note: "Average" and "HR" modes use different averaging methods. The former uses
"Multi-sample Average" and the latter uses "Single Sample Average".
Time Base: The oscilloscope digitizes waveforms by acquiring the value of an input
signal at discrete points. The time base helps to control how often the values are
digitized. Use the SEC/DIV knob to adjust the time base to a horizontal scale that suits
your purpose.
Push the UTILITY button and press Acquire softkey to set the acquisition parameter.
