Munich, February 22, 2015 - Today, Bluetooth modules are used in mobile phones, automobiles, smart homes and other IoT applications. Correspondingly, manufacturers and integration experts have higher testing requirements. Rohde & Schwarz helps them optimize test performance, minimize test time and save considerable cost. The R&S CMW500 Broadband Wireless Communications Test Set is the only 38 signaling test items defined by the Bluetooth Technology Alliance and other cellular technologies such as LTE, LTE-Advanced and WCDMA, as well as non-cellular technologies such as WLAN and GNSS. Test the solution. The Bluetooth Technology Alliance (SIG) has certified this RF test solution.
RF signalling test and fast spectrum measurement
Before sending Bluetooth products to the Bluetooth Certification Test Center, developers can use the R&S CMW500 to thoroughly test their products to optimize their designs. The test platform offers unparalleled flexibility due to its parametric test concept that allows developers to set all their own parameters. Thanks to the easy-to-use R&S CMWrun automated test sequence tool, they can also use this compact solution to perform Bluetooth basic rates in accordance with the Bluetooth Core Specification 1.2, 2.0, 3.0+HS, 4.0, 4.1 and 4.2, with enhanced rate and low Bluetooth. Automated pre-certification testing of power consumption.
The extremely fast speed of the R&S CMW500 is great for developers. For example, when performing the complex spectrum measurement part of the Bluetooth certification test, the R&S CMW500 can output the first test result in less than one second, simplifying the optimization task. . The solution is also ideal for general integration and coexistence testing, for example, to check if WLAN and Bluetooth transmitters interfere with each other in a certain frequency band.
New option for Bluetooth audio testing R&S CMW-KS602
People who are using a computer or who can't liberate their hands while driving rely on Bluetooth headsets and car Bluetooth hands-free devices to make calls. In addition to RF signaling testing, Bluetooth headsets or car hands-free device manufacturers can now use the R&S CMW500 to test the audio characteristics of their products to ensure the quality of their products. Rohde & Schwarz's test platform can be used to optimize products during the development phase and to verify audio characteristics.
When establishing a Bluetooth connection, the flexible R&S CMW500 can operate as a master or slave. It supports hands-free audio gateway mode, authentication when pairing Bluetooth devices with Bluetooth headsets, and volume control for microphones and Bluetooth headsets. It supports a variety of speech coding including CVSD and mSBC.
R&S CMW platform: the right solution for all M2M/IoT needs
For users who only perform Bluetooth and WLAN non-cellular integration tasks, the R&S CMW270 Wireless Connectivity Tester is a more economical solution. The RF measurements of the R&S CMW270 are also certified by the Bluetooth Technology Alliance. The R&S CMW290 Functional Tester supports all common cellular and non-cellular mobile communication standards. Wireless module integrators require extensive functional testing of hardware and applications. The R&S CMW290 offers all the necessary measurement functions as well as an excellent price/performance ratio.
Rohde & Schwarz demonstrated the R&S CMW platform at booth C40 in Hall 6, Global Mobile Communications Conference in Barcelona. The latest R&S CMW-KS602 Bluetooth audio test option was released in March 2016.
Sex Toy Vibration Motor voltage is lower than 6 v, small size, shaking force is strong, the price is cheap. Concrete can be customized according to the requirements of various parameters of the Vibration Motor!
Copper
tungsten steel material
plate material
Vibration of the motor head material, copper, tungsten steel material, plate material, place head motor with different material, different vibration strength, the unit price is different
Operating temperature range:
Sex Toy Vibration Motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a Micro Vibration Motor For Sex Toy is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Sex Toy Vibration Motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of Micro Vibration Motor For Sex Toy is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
