2.6.4 Using Ref

The reference control saves waveforms to a nonvolatile waveform memory. The

reference function becomes available after a waveform has been saved.

Recall the reference waveform on the

screen.

Turn off the reference waveform.

NOTE：

●

The FFT of a waveform that has a DC component or offset can

cause incorrect FFT waveform magnitude values. To minimize

the DC component, choose AC Coupling on the source

waveform.

● To display FFT waveforms with a large dynamic range, use the

dBVrms scale. The dBVrms scale displays component

magnitudes using a log scale.

● The Nyquist frequency is the highest frequency that any real-time

digitizing oscilloscope can acquire without aliasing. This

frequency is half that of the sample rate provided it is within the

analog bandwidth of the oscilloscope. Frequencies above the

Nyquist frequency will be under sampled, which causes aliasing.
