DSCope is a USB – -based oscilloscope.Sampling part of the same based on Xilinx Spartan – 6 + FPGA architecture of SDRAM, analog front end the difference signal and the structure of the variable gain amplifier, provide 50 MHZ analog bandwidth, as well as the maximum 200 MHZ single channel sampling frequency.
The main technical indicators are as follows:
Analog bandwidth: 50 MHZ
Maximum sampling rate: 200 MHZ @ 1 Channel / 100 MHZ @ 2 Channels
Real-time sampling depth: 1 m
A single sampling depth: 32 m @ 1 Channel / 16 m @ 2 Channels
Input channel number: 2 Channels
Vertical sensitivity: 10 mv/div ~ 2 v/div (x1 probe) / 100 mv/div ~ 20 v/div (x10 probe)
Input coupling way: AC/DC/Ground
Input features: 1 M Ω / ~ 15 pF
Overvoltage protection scope: + 100 V (DC + AC peak)
DSCope analog front-end circuit adopts fully differential structure.Compared with single-ended structure has a prominent common-mode noise and power supply noise suppression capability, as well as reduce EMI interference.Make the reduction of measured signal can be more real.
DSCope analog front-end circuit of fully considering the gain bandwidth flatness.Guarantee of arbitrary frequency component in the bandwidth at the same gain.In observing the digital signal, can better restore jump along the digital signal, are more likely to make correct judgment for signal quality.
DSCope with real-time sampling storage depth of 1 m.Storage depth determines the oscilloscope ability to analyze the phenomenon of high frequency and low frequency at the same time, including the low speed signal of high frequency noise and high speed signal of low frequency modulation.As for the importance of the oscilloscope used students should be very clear.DSCope original super long storage depth (16 m / 32 m) of a single trigger sampling function.Make observations collected at the same time waveform of the whole process and the details of the specific time point is possible.Below for DSCope sampling to passive crystals on electricity and vibration of the whole process.
DSView DSLogic/DSCope using the same PC software, also based on open architecture
DSView supports multiple model, logic analyzer/oscilloscope data recorder, etc.On the connection of different hardware devices automatically jump to the corresponding operation mode.For example, when DSLogic after connect to PC, DSView will automatically activate the interface of logic analyzer;After the DSCope connected to the PC, DSView will automatically switch to the oscilloscope operating interface.
Switch between DSView support multiple devices.On a PC can be connected to many sets of DSLogic equipment at the same time, or DSCope equipment, or DSLogic + DSCope device (depending on the PC a few USB interface).DSView can manage these devices at the same time, only need to click the mouse can switch to connect at will on any device.This enables the use of simple more DSLogic and DSCope equipment to expand the number of channels.
