built-in metering table was a very good tool, however, when you make movies and TV series that are relatively cautious about program production, the reflection metering table may cause a deviation in the exposure volume. Although Sony's camera has improved, there are different types of sensitive parts in the digital camera, allowing users to select. Users can select a small block in the center of the screen, which can be the lower half, the upper half or the whole screen for measurement and pro

amplification, drive relay.Generally, an integrated signal amplifier chip is used to amplify the signal. CX20106 is a dedicated integrated preamplifier for Sony, consisting of preamplifier, limiting amplifier, bandpass filter, detector, integrator and integral circuit. The preamplifier has an automatic gain control function to ensure that the amplifier has a hig

Processing Program and determines that the event type is a data sending event based on the bo Bit, it calls the GPIB data sending program and sends the remaining data in the buffer zone to the GPIB bus in sequence. 3. Running status and Result The design of the RS232-1 GUI controller in this article has been successfully used in the connection between the computer and the tds210 oscilloscope. Figure 6 shows the display interface of the Computer Super

chips. When debugging a driver, in addition to fully understanding the data sheet of the chip, and in the process of software height, we also need to see whether the signal level we expect to occur on the chip. For example, when we write the driver, we need to write the I/O port to operate the peripheral chip, when writing the corresponding I/O port, we know that the corresponding chip signal should be valid, sometimes we need to verify whether the expected occurrence, which requires an

example, the test process of the key module leakage analysis, test adequacy measurement, code static quality analysis and collapse of the white box-level capture and analysis. Suppose you have doubts about the test results. You can use the client's code coverage visualization feature. Direct validation of related results.In addition, all the data of the nebula test can be traversed in the version number. All of the data analysis results specifically consider the aggregation requirements of the

The power ripple index of the DC/DC module is an important parameter. A clean power supply is a prerequisite for the stable operation of the digital circuit and an important guarantee for the parameters of the simulator. To determine the power quality, the Output Ripple of the DC/DC module must be measured. However, the ripple value measured by many people is usually hundreds of music videos or even hundreds of music videos, which is far greater than the maximum ripple value provided by the devi

widening, line current increase, the operating temperature rise, the pipeline will be thermal breakdown. Of course, the same problem can be caused by the breakdown of the row amplitude adjustment tube and the lower damping diode. I found in practice that the 6th situation raises a high probability of a problem, and the 8th is not easy to think about. The operating temperature of the pipe is closely related to its base-pole excitation, and I have observed many kinds of monitors such as Adi, Phi

I recently encountered some problems when debugging I2C. I hope you can help me with similar problems. Keywords: I2C sub-steady state low speed signal dejitter [Prelude]In the system, the I2C slave function must be implemented in the CPLD to communicate with the I2C interface of the CPU, so as to expand the gpio port of the system. Therefore, according to the requirements of I2C protocol, an I2C slave module and testslave module are compiled with OpenGL, and then simulated and verified in Model

The company bought an oscilloscope a few days ago, and the process was like this: 1. The development department bought an oscilloscope and found a proxy for XX Company in Guangdong on the Internet. 2. So I called:Engineer a said: How much is XX oscilloscope? Sales lady B said: "XXX price" Engineer a said: We are going to buy a batch. Can we get a discount. Sales

For example, capacitors are used in automobiles, but there is no requirement in the measurement content in the teaching materials. You can add experimental items for measuring capacitors. There are many sensors on automobiles, some sensors can be directly measured with A multimeter, so the experimental items of the measurement sen
