Roll mode Scrolls sequential waveform points across the display in a right-to-left rolling motion.
Works at sample rates up to 10 MSa/s with a maximum record length of 40MS.
Filters
Sin(x)/x Interpolation
On/off selectable FIR digital filter. Digital signal processing adds points between acquired data
points to enhance measurement accuracy and waveform display quality.
