The Need for Spectrum Analyzers and Calibration

Working in the field for service or repair of electrical systems or devices makes it imperative to understand and analyze the electrical signals that are transmitted by the system or device. Analyzing the properties of the signal helps the technician to understand the performance and process protocols that will answer troubled issues. Allowing the signal to pass through a passive receiver that displays the signal helps in the understanding the signal characteristics. This receiver is termed as the spectrum analyzer. The raw signal displays voltage, wave shape, power, and frequency and period information.
Spectrum analyzers can interpret signals such as:

•    voice
•    data
•    sound
•    power

In simple terms any signal depending on the application can be understood and the way it behaves gives the technician background information. A basic spectrum analyzer is the GW INSTEK GSP 810 model that is digitally synthesized, displays RF (radio frequency) measurements up to 1 GHz (gigahertz). Measuring the quality of distortion with respect to:

•    modulation
•    distortion
•    noise

And understanding the spectral characteristic of communications signals is critical where bandwidth is a scarce resource. Measuring distortion is important for communication applications. Along with a spectrum analyzer use of a digital clamp meter gives the technician an all-round capability to check basic electrical parameters of voltage, current and resistance of the power source. Fluke digital clamp meters are the ideal adjunct for such applications.

Tridinamika in Indonesia is a reputed and trusted source for test and measuring equipment. They also provide the service of calibration as a complementing adjunct to their business. Thermometer calibration services along with certification ensure that the equipment is performing within specified parameters.
