Tridinamika is
Indonesia’s main supplier of spectrum analysers, boasting a whole range of
brands from different regions of the globe. Spectrum analysers are instruments
that determine the amount of input signal against frequency throughout the
instruments’ entire frequency range. Their main purpose is to determine how
much power known and unknown signals of the spectrum have a useful aspect in
the characterization of electronic devices.
Spectrum analysers can
be classified as a certain type by considering the methods that are used for
getting a signal’s spectrum. Basically, there are two types of spectrum
analysers – swept-tuned and FFT-based. A swept-tuned spectrum analyser makes
use of a superheterodyne receiver for down-converting a certain part of the
input signal spectrum (this can be done with a mixer and a voltage-limited
oscillator) into a band-pass filter’s center frequency. On the other hand, an
FFT spectrum analyser calculates the Discrete Fourier Transform, otherwise
known simply as DFT, a mathematical process which converts the input signal’s waveform
into its frequency spectrum’s components.
Spectrum Analyser Form
Factors
There are four form
factors spectrum analysers may fall under, namely networked, handheld,
benchtop, and portable. Networked spectrum analyzers don’t come with a display,
but they are capable of linking the analyser to a network and keep track of
various devices simultaneously. Handheld versions are obviously suitable for
scenarios where the tool needs to be small, light and compact. Benchtops come
in handy for applications in which the device must be plugged into an electric
socket (such as in production areas or laboratories). Finally, portable
spectrum analysers are those that must be used outdoors or must simply be
carried around during use. Discover Tridinamika spectrum analysers today.
