* Denotes warranted specifications, all others are typical. Specifications are valid after a 30-minute warm-up period, and ±5 °C from annual calibration temperature.
1 Full scale is defined as 8 vertical divisions. Magnification is used below 5 mV/div. Below 5 mV/div, full-scale is defined as 40 mV. The major scale settings are 5 mV, 10 mV, 20
mV, 50 mV, 100 mV, 200 mV, 500 mV, 1 V.
2 Vertical resolution for 8 bits = 0.4% of full scale, for 12 bits = 0.024% of full scale.
3 13 GHz DSP enhanced bandwidth not applicable at 5 mV/div.
10 11.8 GHz analog bandwidth at 5 mV/div for DSO91304A and DSO91204A models.
11 Calculated from the bandwidth.
12 Input impedance is valid when V/div scaling is adjusted to show all waveform vertical values within the scope display.
