Used WILTRON 561 #9160772 for sale

WILTRON 561 is an electronic test equipment used to measure the performance of radio frequency (RF) components, antennas, and related systems in the field of radio communications. It is one of the most widely used instruments for evaluation in the radio field. 561 is a lightweight, portable instrument designed to measure the essential characteristics of RF components and other elements in a communication equipment including Frequency, RF Power, and VSWR (Voltage Standing Wave Ratio). It operates over a frequency range of 50 kHz to 2 GHz and features a large, easy-to-read LCD display. An internal memory allows for recall of measurement results for later comparison. It can be powered from a built-in, rechargeable NiCad battery or from an external source. It also has an RS-232 interface to allow precise control and data logging while the instrument is in operation. WILTRON 561 measures frequency and VSWR of any given system with accuracies better than one per cent. The instrument's Frequency Measurement section displays frequency range to its highest resolution, using a graphical outlay of the Unit frequency. The VSWR measurement function displays direct SWR and Return Loss measurements, based on the frequency range automatically generated. The RF Power measurement section can be used to measure input power to a transmitter, antenna machine or any other component in a communication tool. In addition, 561 has other features such as an adjustable signal attenuator, an adjustable marker within its frequency range, and signal filtering. The adjustable marker helps in setting the desired frequency, while signal filtering helps reduce noise in the measurement processes. WILTRON 561 also has an easy to use, real-time trace option that allows users to draw and maintain the trace of a signal while it is in operation. All of these performance enhancers make 561 a versatile tool for measuring and troubleshooting communications systems. Overall, WILTRON 561 is a highly functional and reliable instrument for testing and analyzing the performance of RF components and communication systems in the radio field. It is easy to use, lightweight, and provides a host of features to enable precise measurement of RF power, VSWR, and frequency. With its high-level performance and capabilities, it is a valuable asset for any radio professional.
