Checked at 5 mV/DIV for common mode signals of six divisions or less with
the VAR and POSITION control adjusted for the best CMRR at 50 kHz.
Risetime is calculated from this formula: Rise Time = Bandw~:i (-J dB) s

Useful storage performance is defined as the frequency where there are 2
samples per sine wave signal period at the maximum sampling rate. This
yields a maximum amplitude uncertainty of 5% (Maximum sampling rate is
20 MHz).
Display waveforms are calibrated for 25 points per division.
