Ease of use of DPO4000 probe interface

tekvpi new probe interface provides outstanding versatility and ease of use

tekvpi (tekvpi general probe interface) structure introduces the next generation of tekvpi probe interface structure by introducing a series of new tekvpi probes with universal, rich functions and easy use. These probes are designed for the latest generation DPO4000 and midrange DPO7000 series DPO oscilloscopes of Tektronix. The following describes the evolution of tekvpi probe interface, the characteristics of tekvpi design and the new tekvpi probe

Evolution of Tektronix probe interface

in the past 50 years, various oscilloscope probe interface designs have been evolving to meet the requirements of improved instrument bandwidth speed and measurement performance. In the earliest times, banana plugs and UHF connectors were usually used. In the 1960s, ordinary BNC connectors became the commonly used probe interface type because BNC was smaller and more frequent. At present, the BNC probe interface is still used in the design of testing and measuring instruments. At present, the BNC connector with higher quality provides the maximum available bandwidth function close to 4 GHz

in 1969, by introducing the 7000 series probe interface structure, Tektronix introduced a common BNC probe interface design alternative. The 7000 series design uses BNC type connectors to transmit the collected analog signals, but an additional analog coded scale factor detection pin is provided as part of the mechanical and electronic interface design, so that the compatible oscilloscope can automatically detect and change the vertical attenuation range displayed by the oscilloscope, including the attenuation range setting of the 7000 series probe

in 1986, the introduction of tekprobe probe interface structure further enhanced the probe availability. Tekprobe BNC level 1 design provides analog coded scale factor detection pins, expands the attenuation range provided in the 7000 series interface, and supports traditional 7000 series probes. Tekprobe BNC Level 2 design has also been introduced by tekprobe to meet the working power supply requirements of "active" probe types, including transistors, ICs or other active devices as part of the probe signal conditioning network design. Tekprobe BNC Level 2 further expands the function of level 1 design. It increases the communication function between probe and oscilloscope, improves the availability of increasingly perfect probe types, and realizes calibrated offset at the probe tip

in 2001, the further improvement of the function of TekConnect probe, coupled with higher probe bandwidth with load error exceeding ± 1.0% or instability, high reliability of mechanical and electronic design and improved ease of use requirements, led to the emergence of TekConnect advanced probe interface structure, providing the best signal fidelity and maximum bandwidth. Since the maximum available bandwidth of tekprobe interface designed with BNC connector is limited to about 4GHz, TekConnect interface design structure adopts BMA connector (specification and performance are similar to SMA connector), which can support the signal path performance of High Fidelity electrical interface with at least the highest 18GHz bandwidth, so as to support the function of Tyco's highest bandwidth oscilloscope. TekConnect design adopts a variety of mechanical design improvement functions, which can easily and reliably connect the forward locking TekConnect probe mechanism to the oscilloscope with one hand. TekConnect design further expands the communication function of probe and oscilloscope. It is no longer limited to read-only function, but provides read-write probe control function, and realizes advanced functions, such as electronic calibration and adjustment, probe setting parameter soft switch, cascading other probe supporting adapters, etc. Today, tekc's connect design structure to solve global climate difficulties still represents the highest level of advanced detection function of tekc's highest performance oscilloscope

launch tekvpi's next-generation tekvpi probe interface

in 2006, tekvpi launched the latest generation of digital fluorescent oscilloscopes: DPO4000 and DPO7000 Series Oscilloscopes at the middle end, in which tekvpi (tekvpi general probe interface) is used as a new probe interface structure based on the principle of heat balance and circular mixing, so as to provide convenience, versatility and other performance characteristics that are very important to users of this kind of oscilloscopes. Tekvpi uses tekvpi's more than 50 years of probe product design experience and combines the characteristics and advantages of tekprobe and TekConnect probe categories to create a new tekvpi series of probes

tekvpi's functions

versatility and ease of use are the main features of tekvpi probe design, which is realized by communicating with tekvpi oscilloscope host instruments. Because China's extruder products are closely connected with strategic new industries, intelligent two-way oscilloscope/probe communication is realized. Tekvpi probe is designed based on microprocessor and has the functions of EEROM memory and bidirectional serial interface communication. Tekvpi's design structure improves the user's ease of use when setting the probe. The user can easily select the displayed probe status and setting information, and can obtain accurate probe measurement performance results. All this is designed to simplify and improve the user's test and measurement experience

tekvpi probe settings and user interface

each tekvpi probe has a set of rich control functions and indicators located in the probe compensation box ("compbox"), so that users can quickly and easily obtain the most frequently required setting control and working status of the probe. The diaphragm keyboard button sealed on the probe compensation frame has a clear label, and the size is appropriate to the finger. The user can simply control the probe setting. The two-color or three color LED indicators on the probe compensation frame are clearly labeled, so that users can easily understand the probe settings and key working status information. In addition to the traditional probe control and indicator functions mentioned above, tekvpi also launched a new easy-to-use function probe menu button. All tekvpi probes have a special menu button located on the probe compensation box, so users can quickly and easily enter the graphic probe menu screen on the tekvpi host oscilloscope instrument. The instrument probe menu screen and other displayed notification icons provide perfect probe information, including probe model, probe serial number, connected probe channel number, probe working status and warning, and probe diagnosis, to assist in completing commissioning events. In addition, the probe setting control function can be set, changed or monitored from the instrument display screen. In order to assist the user in setting the test and measurement configuration of the application, the tekvpi host instrument also records and saves the setting file of the probe configuration (SAV
