Channel 2 is fed with the initial signal. The trigger output is connected by cable to input 3. Cursor A is set at the trigger time (-4ns, but it is not important). Cursor B is set at the very beginning of the trigger output edge. The result is a delay of 350ns. If you change the trigger level (marked “T” on the right), the delay doesn’t change at all. USB-GPIB Converter. Connect USB directly to instrument and control it via GPIB. This does not connect to a PC directly.
The device’s dimensions remained practically the same, and on the table, it stood exactly in the place of the previous model. A review would not be interesting at all without an “autopsy”. The autopsy will be done in two areas – hardware and firmware analysis. Hardware This work was inspired by the efforts of [cibomahto], who spent some time controlling the Rigol with Linux and Python. This work will plot whatever is being captured by the scope in a window, in Linux, but sometimes you just need a screencap of whatever is on the scope; that’s why there were weird Polaroid adapters for HP scopes in the day. The Rigol DS1054Z represents a remarkable breakthrough in price and performance. It's one of the best general-purpose 4 channel digital storage oscilloscopes available for the maker electronics space.Rigol is a brand of oscilloscopes and multimeters made by Rigol Technologies. They are used to measure the electrical signals in electronic devices. If you read the documentation superficially, the question may arise – how does the device provide 12 bits with the 8-bit ADC? The answer is quite simple – by summing the samples. In 12-bit mode, the sum of 16 consecutive samples would give an additional four bits while proportionally decreasing the frequency. And it’s not Rigol who are such “crooks”. – There are similar mechanisms in the devices of many companies. Unfortunately, high-speed ADCs of 12-14 bits are more expensive, and the circuitry of the oscilloscope becomes more complicated. Oscilloscopes with more than 14 hardware bits are very hard to find (and have a case of money) – this is one reason why it is impossible to test a quality audio channel with an ordinary digital oscilloscope. Its eight-bit resolution is simply not enough to catch distortion at the 16-24-bit level. Some bugs are not critical (but this is normal, as it is a very complex device, and the price is not great)
The usage of this python script is as simple as plugging the DS1054Z into your USB port and running the script. A PNG of whatever is on the screen then appears on your drive. Testing has been done on OS X, and it probably works on Linux and Windows. It’s a simple tool that does one job, glory and hallelujah, people are still designing tools this way. When I was choosing an upgrade, I, of course, looked to see if there is any other option of Rigol that meets the initial criterion “inexpensive for 4 channels”. The following is a brief comparison of the Rigol series. The power wire is angled and (in my opinion) at the wrong angle – the power connector is mounted on the side, but the supplied wire is facing outward, not toward the center of the device. A little bit about frequencies: in spite of advertised capture frequencies of 500 MHz and higher, above 100 MHz, logic analyzer clips make such an impact on the circuit that its behavior becomes absolutely different from the state without clips. But even leaving this aside, let me quote an excerpt from a description of the 1000z series logic analyzer: Summing up, I can say that the result is achieved – I got the device which I am used to the number of channels I need. FAQ Is Rigol any good?The Rigol DS1054Z has the same sampling rate, but it is more expensive than the Siglent Technologies SDS1202X-E. The Rigol DS1054Z also has a wider bandwidth, but it can be used with 4 channels at a time, while the Siglent Technologies SDS1202X-E can be used with 2 channels at a time. The particularly large TFT color displays are very easy to read. Thanks to an intelligent system for displaying or masking information, the largest possible area is always available for displaying signals. The signal curves, the FFT display, and other functions can be shown simultaneously on the display. Model The ability to easily move between long record lengths, fast capture, a variety of persistence modes, and onboard waveform analysis makes RIGOL's core oscilloscope technology an important capability for engineers from maker projects to large scale R&D. Period, Frequency, Positive Pulse Width, Negative Pulse Width, Positive Duty Cycle, Negative Duty Cycle, Matching with the ADC input. Most modern high-speed ADCs use a differential input. The input amplifier receives the signal through one wire (coaxial) and outputs two signals (mutually inverted) to the ADC. The differential line increases resistance to interference.
