found on the cable's data sheet) in your test setup and analyze your

the option.

Interpolation - 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 Filter - Enhanced Resolution (ERES) filtering increases vertical
resolution, allowing you to distinguish closely spaced voltage levels.
The tradeoff is reduced bandwidth. The functioning of the
instrument's ERES is similar to smoothing the signal with a simple,
moving-average filter. Use ERES on single-shot waveforms, or where
the data record is slowly repetitive (when you cannot use averaging).
Use it to reduce noise when your signal is noticeably noisy, but you
do not need to perform noise measurements. It also may be used
when performing high-precision voltage measurements: zooming
with high vertical gain, for example.
