:TIMebase Interpolation Commands

To improve sampled waveform reconstruction and improve the accuracy of measurements, at the expense of consuming more sample memory, a sin(x)/x finite impulse response (FIR) digital filter can add interpolated points between the points that are actually sampled by the oscilloscope hardware. As long as the highest frequency in your waveform is less than the oscilloscope's sampling rate divided by four (and is less than the bandwidth of the oscilloscope), your waveform will be accurately reproduced.

Use the :TIMebase:INTerpolate commands to configure the interpolation settings.

In the graphical user interface (GUI), these settings are made in the Acquisition tab of the Infiniium Scope Setup dialog box.
