5438 controls a normally open relay to close. P1.4 is used to receive feedback signals. In fact, the relay pulls the level down after closing. This low level enters P1.4. I measured the pin voltage an...
The radio frequency identification (RFID) market is experiencing strong growth, with sales reaching $1.7 billion in 2004 and expected to reach $5.9 billion in 2008. This surge in demand is driven b...[Details]
Medical and industrial applications often require isolation voltages of 2500Vac or higher for patient and equipment operator safety. The isolation barrier must not only transmit power to the sensin...[Details]
Digital-to-analog converters (ADCs) provide the critical conversion of analog signals to digital signals in many systems. They perform amplitude quantization of an analog input signal to a binary fini...[Details]
In some applications, such as data loggers, it is desirable to have multiplexed analog outputs. When only a single output is active at a time, a voltage-output DAC">digital-to-analog converter (DAC) a...[Details]
TD-SCDMA terminal conformance test includes three types of tests: RF index test (reference standard: 3GPPTS34.122), protocol signaling test (reference standard: 3GPPTS34.123) and other tests (refer...[Details]
To ensure the success of China's TD-SCDMA network commercialization, operators and equipment suppliers need to conduct a large number of tests on networked equipment, among which RF testing is...[Details]
