Frequently Asked Questions

What is the maximum analog bandwidth of the DSOS804A model?
The DSOS804A model supports an analog bandwidth of up to 8 GHz when two channels are active. When all four channels are active, the system bandwidth operates at 4 GHz.
What vertical resolution options does this high-definition oscilloscope provide?
It features 10 bits of ADC vertical resolution natively, and can scale up to 16 bits when operating in high-resolution mode.
What are the primary differences between the DSO and MSO models?
Both DSO and MSO models include 4 analog channels. However, the MSO models are equipped with an additional 16 digital channels for mixed-signal logic analysis.
What is the dynamic range and offset capacity for the 50 Ω path?
For the 50 Ω signal path, the offset range covers all vertical ranges at ±12 divisions or ±4 V (whichever is smaller). The dynamic range is +4 divisions from the center of the display screen.
What are the physical dimensions and weight of the frame?
The physical dimensions with the feet retracted are 33 cm (Height) x 43 cm (Width) x 23 cm (Depth). The frame itself weighs 12 kg (26.4 lbs), with a total shipping weight of 20 kg (44.1 lbs).
