1. Denotes warranted specifications, all others are typical. Specifications are valid after a 30-minute warm-up period and ± 5 °C from firmware calibration
temperature. Input impedance is valid when V/div scaling is adjusted to show all waveform vertical values within the oscilloscope display.
2. Vertical resolution = 0.4% of full scale(≤ 5 GSa/s) or 0.1% of full scale(10 GSa/s or 20 GSa/s).
3. 50 Ω input: Full scale is defined as 8 vertical divisions. Magnification is used below 2 mV/div, full-scale is defined as 16 mV.
The major scale settings are 5 mV, 10 mV, 20 mV, 50 mV, 100 mV, 200 mV, 500 mV, 1 V. Testing is at maximum sample rate.
1 MΩ input: Full scale is defined as 8 vertical divisions. Magnification is used below 2 mV/div, full-scale is defined as 16 mV.
The major scale settings are 5 mV, 10 mV, 20 mV, 50 mV, 100 mV, 200 mV, 500 mV, 1 V, 2 V, 5 V. Testing is at maximum sample rate.
4. Calculation based on Tr = 0.43/BW.
5. Calculation based on Tr = 0.31/BW.
6. 6 GHz and 8 GHz bandwidth supported in 2-channel mode. If all four channels are on, a maximum bandwidth of 4 GHz is supported.
7. For a 10:1 probe on the 1 MΩ input, vertical scaling is multiplied by 10.
