Time is money. Making sure your teams have what they need to use time effectively is part of smart cost control. Tektronix offers asset management solutions to help businesses in every industry maximize uptime and save money. These solutions can help in the following five ways to keep your work flowing smoothly.
The defining mark of today’s new car is multiple electronic systems and devices. With the volume of gadgets, there comes greater complexity. Most high-end vehicles now feature advanced driver-assistance systems (ADAS), on-board diagnostics, multiple cameras, and complex information/entertainment systems. No wonder one example of the wiring harness in a high-end luxury vehicle can weigh as much as 110 lbs.
As far back as the early days of wireless communications, designers and engineers have been concerned with electromagnetic interference (EMI). Tektronix has been a leader in designing and producing several series of analyzers to help detect and combat EMI throughout the testing phases of research and manufacturing. Tektronix analyzers are known for their ability to instantly scan broad spectrum spans and display easy-to-read test results for better overall EMI detection.
Tektronix is a globally-recognized source of equipment for engineers, scientists, and technicians. Known for their innovative measurement technology, they have created tools like oscilloscopes that have aided in the advancement of fields like health, communication, and space science. There are new discoveries in science and technology virtually every day, so it’s imminent that what used to be some of the company’s greatest products are replaced with newer, upgraded models. But just because they’ve been replaced doesn’t mean they’re forgotten. Here are some of the best discontinued oscilloscopes from Tektronix.
To prevent interference on receiving apparatus, for example, audio and TV receivers or computer systems, signals generated in the line supply and the radiated electromagnetic field of radio frequency from electrical equipment may not exceed certain limits. For this, the IEC makes recommendations. A special committee of the IEC, the CISPR (International Special Committee on Radio Interference), has published several definitions concerning measuring sets and measurement procedures for the various types of interference-producing equipment.
The 15-MHz portable dual-trace oscilloscope Philips PM 3226 is a compact, lightweight instrument featuring simplicity of operation, for a wide range of use in servicing, research, and educational applications. Other features include provision for chopped or alternate display of Y signals, automatic triggering, mains triggering, and triggering on the line and frame sync pulses of a television signal. The cathode-ray tube displays a useful screen area calibrated into 8 x 10 divisions by an external graticule.
Very often hum is present on the signals under test. This can be easily determined from the screen because the hum is related to the line frequency. If a signal shows a kind of unexpected amplitude modulation, switching back the time-base setting to about 5 to 10 or 20 ms/div, and switching over the trigger source selector to MAINS (or LINE), will generally result in a stable picture in the event of hum.
While measuring complex waveforms in digital techniques, mistakes can be made very easily. In this section, examples of this are presented. Some of them are explained in detail, to gain knowledge about the possible reasons for false triggering, which leads to wrong timing displays on the screen.
In digital techniques, it can happen that two pulses appear in a timerelated sequence, but that the second pulse appears a little later, with a delay, with respect to the first one.
Basically, the current probe is a transformer of which the primary winding is the test lead through which the current is measured. The probe head consists of a ferrox-cube core and the secondary windings of the transformer. The core can be split into two parts to clip it simply around the measuring lead. The white-colored part of the probe head can be moved backward and forwards to clip it around the lead. A voltage is developed in the transformer secondary windings by the magnetic field around the measuring lead. This voltage is fed to an amplifier box, the output of which is fed to the oscilloscope. The output cable from the amplifier must be terminated with 50 fl at the oscilloscope end (low-ohmic system for 75-MHz bandwidth). Furthermore, if the oscilloscope is set to 50-mV/ div sensitivity, the amplifier box provides calibrated outputs ranging from 1 mA/ div on the screen.
