Bandwidth Limiting

You may sometimes want to limit high frequency noise on a very low bandwidth
input signal. If this is the case, you can limit the channel bandwidth to less than
the full bandwidth of the oscilloscope. Select a different bandwidth by touching
inside the Bandwidth field and selecting a value from the pop-up menu.

Averaging Your Signal

The WaveSurfer MXs-B oscilloscope allows you the opportunity to continuously
average your signal to reduce signal noise and aid in signal evaluation. If you want
to use averaging, select a value here by touching inside the Averaging field and
entering a value up to 1 million sweeps on the pop-up keypad.

Interpolation Settings

Linear interpolation, which inserts a straight line between sample points, is best
used to reconstruct straight-edged signals such as square waves. (Sinx)/x
interpolation, on the other hand, is suitable for reconstructing curved or irregular
wave shapes, especially when the sample rate is 3 to 5 times the system
bandwidth.

Noise Filtering (ERES)

The instrument's enhanced resolution feature improves vertical resolution by a
fixed amount for each filter. This real increase in resolution occurs whether or not
the signal is noisy, or your signal is single-shot or repetitive. The signal-to-noise
ratio (SNR) improvement you gain is dependent on the form of the noise in the
original signal. The enhanced resolution filtering decreases the bandwidth of the
signal, filtering out some of the noise.
