For the introduction of a successful digital technology, proper on-site investigation is the first thing to do. This investigation and its site preparation work should be completed before any digital front-end equipment arrives at the installation to avoid unnecessary delays during the installation phase. On-site investigations should have such considerations as the availability of satellite dish antennas, front-end housing space, rack availability, grounding conditions, and power and cooling requirements. Once the satellite dish is installed, the quality of the received signal can be observed through a spectrum analyzer. The technology of the chromatography workstation to ensure the good reception of the digital signal satellite is basically the same as the analog reception technology. The operator should confirm that the digital signal level and its carrier-to-noise ratio should meet the specification limits of the IRT input signal error correction operation, and at the same time, leave sufficient margin. Digital installation is the same as analog installation, and proper terminal grounding at the front end prevents micro reflections. Although Tianjin Smit Precision Instrument Co., Ltd. does not affect analog signals, they can cause interference between digital signal symbols. Although DCT's adaptive equalizer may be able to correct this problem, there will be an unnecessary requirement for the equalization budget, which will reduce its ability to deal with the reflected waves of the system. Operators should pay special attention to the level setting. It must be remembered that if the digital signal level is 10 dB lower than the corresponding analog signal carrier peak, they will not produce significant distortion. At the same time, we must pay attention to the designated allocation of digital signal frequency. The digital channel will not work well when it is adjacent to the notch channel, because the frequency response and group delay of the notch will produce distortion in its adjacent digital channel. At the same time, it is necessary to confirm that an incoherent frequency sweep system is used in the system. The frequency sweep generator is programmed to avoid placing drifting RF components in the digital portion of the spectrum.
Yeswitch 16MM Metal Switches could be divided into aluminum casing and stainless steel casing and also could be divided into Momentary Switch and self-locking Metal Push Button Switch .
