SARK-110
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. 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.
Its small size does not mean compromising the features and measurement
performances. It has full vector measurement capability and accurately resolves the
resistive, capacitive and inductive components of a load for frequencies up to 230 MHz.
The accuracy is excellent over a broad range of impedances. The functionality of the
SARK-110 is not restricted to antenna analysis, but it is a multifunction instrument
featuring a Time Domain Reflectometer (TDR) 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
connected to a personal computer in combination with the SARK Plots software for
Windows and Android, further enhancing the capabilities of the instrument.
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.
