DBS receiver with direct conversion low-IF tuner Comparison - tuner, video encoding, satellite broadcasting - radio and television network industry
System consists of two main signal processing subsystem, namely, low noise (LNB) down converter and DBS television receiver. LNB down converter in the satellite dish antenna base, responsible for the satellite signal spectrum from the C, Ku or Ka-band down to L-band (0.9GHz ~ 2.2GHz). DBS television receiver in the set-top box inside for the reduced base-band signal, and perform signal processing functions such as demodulation, MPEG decoding, display processing and analog audio / video encoding (NTSC / PAL).

Select key to see the six indicators light sensor - light sensor, the sensor - Electrical industry
Light Sensor The application is extremely common. From the portable consumer market (smart phones, PDA, desktop PC and portable music players, etc.) to the consumer TV Machine market (including LCD, plasma, rear projection and CRT TV, etc.), to medical, industrial and Car Market, optical Sensor Everywhere. Among them, some applications, such as bar code readers, laser printers and auto-focus optical microscope to detect the reflected light on the position induction; other applications, such as digital cameras, cell phones and notebook computers, portable Electronic Products are used to measure the ambient light sensor light volume.

Digital IF and simulation analysis of frequently compared spectrometer - spectrum analyzer - Education Industry
With the ADC, high-performance microprocessors and programmable devices such as devices and Technology Rapid development in recent years, Spectrum Analyzer From Analog IF Time to enter Digital IF Times. Digital IF The use of technology to Spectrum Analyzer The number of indicators have been enhanced significantly. Beijing Rigol call (RIGOL) latest DSA1030A Spectrum analyzer Is used Digital IF Technology, to become one of the few master the technology Spectrum Analyzer Suppliers.
