SARK-110 Antenna Analyzer

Share

The SARK-110 is a pocket size, stand alone antenna vector impedance analyzer that makes available a multitude of features and capabilities which are perfect for checking antennas, antenna feed lines and RF circuits for radio amateurs and hobbyist both in laboratory and in a field operation.

The analyzer features a Direct Digital Synthesis (DDS) generator with a range of 0.1 to 200 MHz and a frequency resolution of 1 Hz. The measurement part provides a precise measurement of the impedance vector including the true determination of the sign of the reactance. Besides it is provided the Open/Short/Load calibration standard for accurate results.


The user interface based on a color display has been designed to be intuitive and easy to use. The graphical impedance displays provide a quick view of the antenna impedance characteristics on a user selected sweep range. This includes the graphical plot of two selectable parameters or in smith chart form. Besides it is included a single frequency measurement mode which presents the complete parameters at a user selectable frequency.

In addition, the analyzer features a TDR (Time Domain Reflectometer) mode which is intended for the location of faults in coaxial cables.

The analyzer features an internal 2MB flash disk for the storage and recall of the measured parameters, screenshots, analyzer configuration, and firmware updates. This disk is accessible via USB so the measured parameters can be also retrieved from the PC and analyzed from the ZPLOTS spreadsheet program.
