In the field of testing measurement, the development of technology has urged numerous mobile portable testing measuring instruments such as spring, and people are no longer subject to fixed test environments such as laboratory, and mobile portable test instruments have brought more time to test and more efficient. Work efficiency.
Adorem2000 is a portable, multi-function test measuring instrument, which is launched by the industry's superior semiconductor company ADI, electronic related professional college students and enthusiasts, with oscilloscopes, network analyzers, spectrum gauges, waveform generators, logic analyzers, power supply Many functions such as data acquisition, enabling students and electronic enthusiasts to test various functions of the circuit at any time, very attractive. The entire suite is 758 yuan on the ADI official agent.
Adol2000 Advanced Active Learning Module
The first look saw Adol2000, you will be very surprised, although there are many features, but the real thing is very small. If you have been in contact with AdalM-Pluto, you look at the appearance of both, mainly, mainly the interface. As a cost-effective, USB-powered software definition instrument, it is not, it is a software definition instrument, no doubt, there is a product that is designed with FPGA, from here we are not difficult to speculate in the future The product of the software definition class may be popular. After all, the design is flexible and cost-saving. Who is not for the premise of expected functionality?
The entire Adol2000 instrument is almost the size of the 4.7-inch iPhone, carrying no stress with you, at least more than the current charging treasure that is often carrying with you.
From the official introduction of Adi, the main function point of Adol2000 is as follows, but some regrets are the current official offer ADALM2000 information is not too much. For the specific performance indicators, it is not enough to understand, only the actual experience is evaluated.
Dual channel USB digital oscilloscope
Dual channel arbitrary function generator
16-channel digital logic analyzer (compatible with 3.3V CMOS and 1.8V or 5V, 100MS / S)
16-channel mode generator (3.3V CMOS, 100MS / S)
16-channel virtual digital I / O
Two input / output digital trigger signals (3.3V CMOS) for linking multiple instruments
Single-channel voltmeter (AC, DC, ± 20V)
Network Analyzer - Circuit Port, Nyquist, Nickles Transfer Drawings. Range: 1Hz to 10MHz
Spectrum Analyzer - Power Spectrum and Spectrum Measurement (Noise, SFDR, SNR, THD, etc.)
Digital bus analyzer (SPI, I2C, UART, parallel)
Two programmable power (0 ... + 5V, 0 ... -5V)
To be honest, I see that Adol2000 is still very surprised. After all, this similar multi-functional instrument is also touched, but it is only such a rich function like Adol2000.
Although the Adol2000 official information is not fully announced, the small partners who have seen Adorem-Pluto will have some interface functions on the AdAlM2000, as shown in the following figure, the housing only leaves the test pin seat interface and MicroSB Power, MicroSB 2.0 Communication / Power Supply Interface, "Device" button bore (for manual access to DFU mode).
The MicroSB 2.0 interface also supports numerous functions, such as large-capacity storage, serial, equipment firmware upgrades, etc.
Another head is the needle signal interface of Adol2000, which is defined as follows:
The main processing chip of Adol2000 is the Zynq-7010 series SOC, plus 512MB SDRAM, 64MB NOR FLASH configuration.
SCOPY software
Adorem2000 is used for the PC side software for SCOPY, which is an open source software that provides an intuitive user graphical interface, even for the first time, it is also very simple, no technical content, it is a familiar process.
Scopy software can also achieve communication with Adorem2000 through USB or network IP. However, it is a bit surprising that the device gets the device that does not recognize the device after the connection, speculation may be released by the firmware version is already released. The version is caused, which is a bit worried that this built-in firmware will affect the accuracy of the measurement. Although Adol2000 This product has been officially launched, there is less current source, so there is not much information on the Internet. In addition, when the Adol2000 is established with Scopy, it is actually the calibration of the instrument.
After the connection, you can find that the ADALM2000 driver is basically no difference in AdAlM-PLUTO.
Similarly, when pressing the device key, let AdAlM2000 enters the DFU mode, and update the firmware later.
Power-on test
Because Adol2000 itself is a test instrument, the author chooses a 100MHz, 1GSA / s sample rate oscilloscope and a 20MHz signal generator as an auxiliary reference, but other instruments such as spectrum Instrument, network analyzer, the author does not, so it is basically no way to discriminate the test results of Adol2000, can only be used as a reference. In fact, the measurement signal reaches a high frequency level. If it is still used in the Adol2000, the author is not too optimistic about the results of the test.
Therefore, in order to try to close to the real test, the IP RF cable used by the BNC interface used in the oscilloscope, the signal generator.
Signal generator
When the sine wave frequency of the signal generator generates a sinusoidal wave frequency or more, the sinusoidal waveform signal is distortion, and the amplitude is attenuated.
If the square wave is generated, the overshoot and ringing of 100KHz will be more obvious, which may still be the best in the test environment, and the impedance is not matched.
However, the author also actually connects the ADALM2000 SCOPY software directly on the ADALM2000 Scopy software directly, and the waveform can be obviously distorted when 10 MHz, but not only the waveform distortion is not only in 16MHz, and the amplitude is also attenuated, so at least From the results, there is more reference value through 100MHz, 1GSA / S oscilloscope.
Oscilloscope
The oscilloscope of the AdAlm2000 can be measured by 10 MHz, and an oscilloscope that exceeds 10MHz signals is not recommended to use the Adol2000 instrument to measure, but if it is more accurately measured, it is recommended to measure signals below 6MHz.
Voltage source
The voltage source of Adol2000 can be powered -5 ~ 0V, 0 ~ + 5V power supply, and can achieve two separate power supply or follow-up power, but only 50mA current is provided.
Voltmeter
The voltage meter function of Adol2000 can achieve +/- 20V DC / AC measurement.
Spectrum analyzer
The ADALM2000 spectrum analyzer function can measure power spectrum and spectrum measurement (including noise, SFDR, SNR, THD, etc.).
Network analyzer
The ADALM2000 network analyzer features three ways of testing frequency feedback, such as circuit port, Nyquist, Nickles transport map, measurement frequency range: 1Hz to 10MHz.
In addition, there are also digital logical logic analyzers, mode generators, and discrete I / O devices, which share 16 signals, with 100MSPS, each pin 4K conversion through analog channel to implement cross-triggers.
Speaking of the feelings that actually use, Adorem2000 as a multi-function test measuring instrument, you can simply summarize the following:
The ADALM2000 will have distortion phenomena when testing the sine wave of 10MHz or more, and after multiple measurements, the ideal test environment is not more than 6MHz at the clock frequency.
As the signal generator, the ADALM2000 is substantially satisfied with the frequency, the waveform OK, and the amplitude is attenuated, and the frequency of the maximum setting on the SCOPY software is much greater than the actual waveform, which is easy to cause misuse; When the square wave is greater than 100kHz, the overshoot and ringing phenomenon is obvious.
Compared with professional oscilloscopes, signal generators, etc., but can meet the usual use (excluding workers engaged in high frequency signals)
Power supply output: 50mA @ + / - 5V output can be applied for application
Software compatibility needs to be improved, sometimes there is no response, and the heat generation is also relatively large.
Small knot
Have to say, although Adol2000 has a rich function, adhering to the midburs, although each function is not top, it is more functions, like usual use or ok, of course, the needle interface provided by AdAlm2000 is It is worth vomiting, if it is only the measurement of the digital logic function, but once the function of the oscilloscope, signal generator, etc., once the high frequency signal is reached, the interface like Adol2000 is completely Not suitable, if equipped with a special BNC transistration, it will be better. However, as a 9-in-1 test measuring instrument, with ease of use and portability, it is also ideal for college laboratories, engineering students, electronic enthusiasts, and gain customers.
