Antenna and Cable Analyzer

December 2, 2015

Bird SiteHawk [2601927]Bird Technologies has introduced the SiteHawk SK-200-TC hand-held antenna and cable analyzer, which operates from 300 kHz to 200 MHz. The instrument detects problems in coaxial transmission lines and antenna systems and pinpoints their source using distance-to-fault measurements.

The SiteHawk SK-200-TC provides the measurement capabilities required to evaluate the performance of a communication system’s transmission path, and has the same features as its higher-frequency counterpart, Bird’s SiteHawk SK-4000-TC, which operates over a frequency range of 85 MHz to 4000 MHz. The SiteHawk SK-200-TC measures 7.2 inches by 3.8 inches by 1.9 inches. and weighs 2 pounds. It has an intuitive user interface displayed on its high-resolution TFT LCD color display that is readable in bright sunlight, and has 16 gigabytes of internal flash memory for storing thousands of traces and measurement setups.

The distance-to-fault measurement indicates VSWR or return loss at various points from the beginning of the transmission line to the antenna and identifies the location of a problem with high resolution. The cable loss function measures insertion loss of the transmission line over a given frequency range.

The instrument makes measurements at up to 0.25 ms per data point of return loss and cable loss as well as VSWR and distance to fault and allows users to set trace capture using 51, 101, 201, 401, 801, 1601 or 3201 data points per sweep. Both X and Y scales as well as measurement units can be changed by the user as can a pass-fail limit with visual indicator. There are six user-selectable markers for direct or difference measurements that can be referenced to the limit line or a recalled trace. A measurement-hold feature also allows a trace to be stored temporarily for analysis. www.birdrf.com.
