oscilloscope for dummies

LPC1549 How to use the J-scope of the Jlink tool to observe variables in real time, without affecting the CPU operation, speed can also depend on Jlink version model. Engineers don't have to buy an oscilloscope anymore, and it's easy to save money. The steps are as follows: I. Jlink tool hardware version and software version, software version to V4.9 and above Model comparison J-link Model Max. No. of variables Max. Sampling freq

, Literature of Duquennoy, Dunkels [16],lunden, Dunkels [17] and Tsiftes, Dunkels [24].4.1 Micro BenchmarkWe measure individual energy consumption by running Contikimac's Tmote Sky mote. We used a 100 ohm resistor in series with the Tmode Sky power supply and then measured the voltage above the resistor using an oscilloscope. The CONTIKIMAC registers the status of the wireless signal on one of the pins of the tmote Sky I/O, where the high level indica

(10001000), the preceding 1000100 is the address, and the last 0 is a read-write bit. The quorum procedure is to monitor for SDA conflicts when starting the condition and sending the address. SDA output high power at ordinary times, read back is low level, indicating that there is a conflict on the bus. oscilloscope Measurement Need to test SCL,SDA at the same time. The oscilloscope two channel open, respe

"Finishing" 61ic.com "Provider" llz77 "Detailed description" IAR for STM8 exact delay function With the IAR for STM8, there is a project to accurately know the number of delay line delay time is how many, the Internet search under unexpectedly did not, and found that a lot of people ask how such a function, I use oscilloscope measurement to do a precise delay function, to share with you friends. The clock start function (16M crystal oscillator) is

Help coal mine customers adjusted for many years terminal resistance, summed up some of the experience for everyone to reference, no reference theory, but are the result of practice. About the terminal resistor: We always remember can terminal to add 120 euro, but that is a short distance impedance matching results, if in the long-distance or add 120 kohm will be very harmful to the signal, because the can transceiver drive capacity is certain, transmitted 5 km, back to the route impedance (can

Recently, there is a product used to the module, because there is no technical support, directly on the machine debugging, test results for the band barrier launch distance of 60 meters. Here are a few knowledge points to apply: 1: The programming operation, actually relatively simple, the modulation signal 315M is the module comes with, does not need the modulation and the demodulation, we only need to control own agreement, I use is the Infrared emission Protocol to control. 2: The transmit bi

oscilloscope concept, in the actual Android-based application testing process, you can see in real-time from the program of various logical body execution rate, frequency and other information, Testers can convert from a traditional black box test of a tested application (which can only see feedback from the program) into an oscilloscope similar to a hardware test, enabling real-time analysis and viewing o

with capacitive coupling at the high impedance input and without DC access to the current at the same-phase input.　　 Figure 1: Error op amp ac-Coupled inputIn fact, the input bias current flows into the coupled capacitor and charges it until it exceeds the rated value of the common-mode voltage of the amplifier input circuit or limits the output. Depending on the polarity of the input bias current, the capacitor is charged to the positive or negative voltage of the power supply. The ampli

neighbor showed him a Tek oscilloscope in the garage, leading Jim himself to the world of analog circuits. Later he worked at MIT's lab to get a job as a technician. MIT, the name of the bull, explains what Jim was up to. His circuit design, hands-on ability, the ability to solve the problem of equipment is self-honed. later he came to Silicon Valley in the West Bank to join national as a analog circuit application engineer. National EM left the comp
