Besides oscilloscope, engineers often use a lot of electronic measuring tools. Ideally, they should be integrated into one instrument, which will greatly reduce the trouble of connection and configuration between instruments and simplify the working table of engineers. However, this is clearly not possible, and instrument suppliers have to weigh the pros and cons and try to integrate as much functionality as possible into the oscilloscope, the most common tool used by engineers. Therefore, which function to integrate and how many functions to integrate become the problem that oscilloscope supplier needs to consider carefully.If the integration is improper, not only does not simplify the work of engineers, but reduces the main performance of oscilloscope.
Integrating some functions of logic analyzer into oscilloscope is the earliest attempt. The integrated oscilloscope is called mixed signal oscilloscope.Many oscilloscope suppliers have successively launched mixed signal oscilloscopes.From the original 2 channel or 4 channel oscilloscope to add 16 logic channels of mixed signal oscilloscope, greatly facilitate the engineer's testing work, especially by the development and debugging of embedded design engineers welcome.
Last year, teck launched an oscilloscope for integrated spectrum analyzer. Integrating spectrum analyzer into oscilloscope is a big challenge. These two kinds of instruments belong to different measurement domains -- time domain and frequency domain. In recent years, wireless applications such as wi-fi, ZigBee, bluetooth, RFID and so on have been increasingly used in embedded systems. More and more engineers need to design digital circuits and rf circuits at the same time, and design engineers must deal with these two fields at the same time. Based on such industry demand, teck launched the MDO4000 hybrid domain oscilloscope last year.Combining oscilloscope and spectrum analyzer capabilities, the MDO4000 provides time-dependent analog, digital, and rf signal observations. By implementing time-dependent multi-domain displays, engineers are able to make accurate timing measurements to understand changes in the frequency domain caused by delays and delays between command/control events in their time domain designs. In addition, because the MDO4000 provides complete system-level observations of time-domain and frequency-domain time correlation, it is easier than ever to find intermittent EMI noise and EMI noise caused by component states.
After the spectrum instrument, another function integrated into the oscilloscope is the digital voltmeter.Not long ago, agilent announced the launch of the 1GHz InfiniiVisionx series oscilloscope, and was the first to add the function of digital voltmeter to the series oscilloscope. Currently, the InfiniiVision2000X and 3000X series offer voltmeter and counter options, among which the voltmeter (DVM) is 3-bit, the counter is 5-bit, and the probe can be Shared with the oscilloscope when working. Voltmeter and counter measurements are independent of the oscilloscope trigger system. They are independent hardware that allows engineers to perform DVM and trigger oscilloscope measurements through the same connection.DVM results are displayed in a continuous seven-segment display, allowing engineers to perform these rapid characteristic measurements with a snap of their fingers.
