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 color display that allows information-rich diagrams.Its small size does not mean compromising the features and measurement performances. It has a frequency range from 0.1 to 230 MHz with 1 Hz of resolution. It has full vector measurement capability and accurately resolves the resistive, capacitive and inductive components of a load. The accuracy is excellent over a broad range of impedances and rivals any of the competitive devices in the market. The provided Open / Short/ Load calibration ensures the highest level of measurement accuracy. There is a transmission line calculator feature that allows adding or subtracting the effect of feed lines.The functionality of the SARK-110 is not restricted to antenna analysis, but it is a multifunction instrument featuring a TDR (Time Domain Reflectometer) 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 when connected to a personal computer in combination with SARK Plots client software for Windows, further enhancing the device's capabilities.The SARK-110 allows you to quickly analyze any antenna over a user defined frequency range. In real time, you can see at a glance the resonant frequencies of the antenna, the VSWR, the complex impedance, reflection coefficient, return loss, and R-L-C as series or parallel equivalent circuits. You can test and tune coaxial cables and phasing stubs. You can adjust and test RF matching networks, antenna tuners, and RF amplifiers without applying power. Besides you can measure the impedance of components such as inductors, capacitors, and traps at RF frequencies. As a signal generator it is ideal for receiver calibration, sensitivity tests and signal tracing.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. This includes the graphical plot of two user selectable parameters in a scalar chart or a complex reflection coefficient in Smith chart form. To help speed up measurements, two markers are available, both of which are user positionable or can operate in automatic tracking mode.The Multiband mode is a unique feature of the SARK-110 whereby it is able to display simultaneously the plot of an impedance parameter in four scalar charts. This feature is ideal for tuning multiband antennas. The SARK-110 provides a single frequency measurement mode that presents the complete impedance parameters at a user selectable frequency. To facilitate the reading, the analyzer displays graphically the R-L-C as both series and parallel equivalent circuit and the SWR as a convenient bar graph.The analyzer uses 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 the SARK Plots client software for Windows.The SARK-110 is as well a hackable device. You can experiment with the device by writing an application using the provided open-source SDK. Besides the SDK includes a device simulator for the PC so you can easily debug your application before loading to the device. For more advanced users, the SARK-110 board provides connections to the STM32 SWD interface so you can use the ST-Link in-circuit debugger or equivalent to program or debug your software.With its pocket size, features, and simple user interface the SARK-110 offers a perfect device for HF/VHF impedance measurements for the RF experimenter and for the amateur radio operator. Whether you are at home in your shack or in the field during a field day or expedition.
