Description

The SARK-110-ULM is the entry-level model of the SARK-110 antenna analyzer series. This is a truly pocket-size device, so you can take it anywhere. The built-in battery lasts up to eight hours on a single charge. It features a graphical display and an intuitive user interface that makes it easy to operate.

The native measurement frequency range is between 0.1 and 160 MHz, but it operates up to 700 MHz with reduced performances. It has full vector measurement capability and accurately resolves the resistive, capacitive and inductive components of a load.

The functionality is not restricted to antenna analysis, but it is a multipurpose instrument featuring a Time Domain Reflectometer (TDR) mode which is intended for fault location and length determination in coaxial cables; as well as an RF signal generator. The analyzer is designed for standalone operation, but it can be controlled from your desktop using SARK Plots for Windows and from your tablet or smartphone using SARK Plots for Android through USB or short-range Bluetooth LE.

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.
