SARK-110-ULM
The SARK-110-ULM is the entry-level model of the SARK-
110 antenna analyzer series. This is a truly pocket-size
device, so you can take it anywhere. The built-in battery
lasts up to eight hours on a single charge. It features a
graphical display and intuitive user interface that makes it
easy to operate.
The native measurement frequency range is between 0.1
and 160 MHz, but it operates up to 700 MHz with reduced
performances. It has full vector measurement capability
and accurately resolves the resistive, capacitive and
inductive components of a load.
The functionality is not restricted to antenna analysis, but
it is a multipurpose instrument featuring a Time Domain
Reflectometer (TDR) mode which is intended for fault
location and length determination in coaxial cables; as
well as a RF signal generator. The analyzer is designed for
standalone operation, but it can be controlled from your
desktop using SARK Plots for Windows and from your
tablet or smartphone using SARK Plots for Android
through USB or short-range Bluetooth LE.
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.
