Agilent6000 series oscillograph Vs. Oscillograph of Tek TDS3000 series
Foreword
The indication quality of oscillograph is great the ability that affects you to undertake effectively designing checking a fault. If your oscillograph has inferior quality only show, you see crucial signal is unusual impossibly. The oscillograph that can show a signal brightness order and degree also can reveal important undee detail, include to announce the signal in all sorts of imitate and digital application is unusual.
This applied guideline compares Agilent 6000 series to mix signal oscillograph (M S O) mix to all sorts of imitate with oscillograph of Tektronix TDS3000 series the indication quality of digital signal. Those who give traditional imitate oscillograph is return to show a result in a few example. We still discuss the method that quantifies indication quality, compare objectively it is more easily to can show to oscillograph thereby.
three-dimensional: Brightness modulation engineer thinks to count word memory oscillograph commonly (DSO) it is with the graph one kind means shows tension, the 2 dimension instrument that time concerns. But oscillograph is subsistent three-dimensional: Z axis. three-dimensional show an order and degree of successive and undee brightness, it is the function that signal produces frequency in place of specific X-Y position. In imitate oscillograph, brightness modulation is vector of oscillograph of electron beam scanning indication natural phenomenon. As a result of inchoate the limitation that is demonstrated a skill by the number, while digital oscillograph replaces imitate oscillograph, also lost this three-dimensional brightness modulation. Now is the good chance that break and regains.
Search signal when you unusual, observing signal of compound modulation imitate especially, be like video signal, magnetic head is read when writing signal and signal of drive of numerical control motor, indication brightness grade is very important. Mix to car, industry in consumable market sundry embedded microprocessor and small controller mix signal application, brightness grade also is extremely helpful. Although you are to watch pure number weaveform, brightness grade also can give out to shake about the edge, the statistical information such as occurrence rate of perpendicular noise and unusual event.
Latter, manufacturer of oscillograph of all and main number already began to offer order and degree of Z axis brightness, with the indication quality of imitated imitate oscillograph, gain the success of different level.
The imitate signal of compound modulation applies
If your job wants to use compound modulation signal, you have the oscillograph of enough indication quality with respect to need, make you can view big prospect above all, look carefully at signal detail through enlarge next.
Compound TV signal
A lot of engineers are familiar with standard NTSC and PAL compound TV signal, this signal belongs to signal of compound modulation imitate. Graph 1 it is what imitate oscillograph captures one frame is compound the photograph of TV signal. When you watch this weaveform with 5ms/div, although existence shows " twinkle " , still attainable embedded shows in place weaveform includes the important information inside subsidiary channels in the human body through which vital energy. The TV stylist that has experience can show from this decide quickly the quality that produces imitate signal.
