Notes:
1) Rise time figures are calculated from: tr = 0.35/Bandwiath.
2) Magnification is used below 7 mV/div range so the vertical resolution and
accuracies are correspondingly reduced. Below 7 mV/div, full scale is defined as 56
mv.
3) The voltage measurement accuracy decreases 0.08% of full scale per °C from the
firmware calibration temperature. This specification is valid for a temperature range
+10°C from the firmware calibration temperature. The specification applies to both
the repetitive and real time modes.
4) The specification applies for bandwidth limited signals (tr = 1.4 x sample interval).
The sample interval is defined as 1/(sample rate). The specification also applies to
those automatic measurements computing time intervals on pulses with identical
slope edges (i.e. pos-pos, neg-neg).
