The SARK-110 Antenna Analyser is a pocket size instrument providing fast and accurate measurement of the vector impedance, VSWR, vector reflection coefficient, return loss, and R-L-C (as series or parallel equivalent circuits).
Typical applications include checking and tuning antennas, impedance matching, component testing, cable fault location, measuring coaxial cable losses, and cutting coaxial cables to precise electrical lengths.
The SARK-110 features a Direct Digital Synthesis (DDS) generator with a range of 0.1 to 230 MHz and a frequency resolution of 1 Hz. The instrument has full vector measurement capability and accurately resolves the resistive, capacitive and inductive components of a load. The measurement reference plane is automatically adjusted via the Open/Short/Load calibration standard for higher measurement accuracy.
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 user selectable parameters in a rectangular diagram or the complex reflection coefficient in Smith chart form. Two markers, either of are user positionable or can operate in automatic tracking mode, help to speed-up the measurements.
Also included is a single frequency measurement mode which presents a complete impedance parameter analysis at a user selectable frequency and displays a graphical representation of the equivalent circuit.
In addition, the analyzer features a FDR (Frequency Domain Reflectometer) mode which is intended for fault location and length determination in coaxial cables.
The analyzer features an internal 2MB flash disk for the storage and recall of measured parameters, screenshots, analyzer configuration and firmware updates. This disk is accessible via USB so the measured parameters can be downloaded to a PC for analysis using the ZPLOTS spreadsheet program or with SARK Plots client software for Windows.
