SARK-110 Antenna Analyzer
£319.99 ex VAT
The SARK-110 is a completely new design concept for an Antenna Analyzer. This is a truly pocket-size device, so you can take it anywhere. It offers a gorgeous 3” high-resolution, active-matrix colour display that allows information-rich diagrams. The user interface has been designed to be intuitive and easy to use. On-screen menus provide user guidance and the operation is mainly controlled by the two navigation keys. The graphical impedance displays provide a quick view of the antenna impedance characteristics on a user selected frequency range.
Its small size does not mean compromising the features and measurement performances. It has full vector measurement capability and accurately resolves the resistive, capacitive and inductive components of a load for frequencies up to 230 MHz. The accuracy is excellent over a broad range of impedance and rivals any of the competitive devices in the market.
The functionality of the SARK-110 is not restricted to antenna analysis, but it is a multi-function instrument featuring a Time Domain Reflectometer (TDR) mode which is intended for fault location and length determination in coaxial cables; as well as a programmable RF signal generator. The analyzer is intended for standalone operation but also operates connected to a personal computer in combination with the SARK Plots client software for Windows, further enhancing the capabilities of the instrument.
Typical applications include checking and tuning antennas, impedance matching, components test, cable fault location, measuring coaxial cable parameters, and cutting coaxial cables to precise electrical lengths. As a signal generator, it is ideal for receiver calibration, sensitivity tests, and signal tracing.
