Sight-float check valve is intended for use in vertical sampling applications and as a means of preventing vacuum scrubber contamination due to over-filling of the vertical sample leg or vessel before draining back into the sample container.
Signal Adapters include circuit board to process wired TV signal and telephone signal from coaxial cable. These wired TV signals and telephone signals are transmitted from a coaxial cable to the circuit board. The main signal output port through which wired TV signal and telephone signal are transmitted from the circuit board to a next signal adapter.
Signal Analyzers employ digital techniques of signal analysis to extract useful information that is carried by the signal. The common procedure used is digital fourier analysis using fast fourier transforms. Fourier analysis produces the frequency spectrum of a time signal. It has two or more input signal channels. To generate results such as frequency response functions, cross spectra, coherence functions and cross-correlation functions dual-channel analyzer is used.
