AA-230 ZOOM RigExpert

AA-230 ZOOM RigExpertAntenna and Cable Analyzer
100 kHz to 230 MHz

The analyzer is designed for measuring SWR (standing wave ratio), return loss, cable loss, as well as other parameters of cable and antenna systems in the range of 100 KHz to 230 MHz. A built-in ZOOM capability makes graphical measurements especially effective. An integrated Time Domain Reflectometer mode can be used to locate a fault within the feedline system.

The following tasks are easily accomplished by using this analyzer:

• Rapid check-out of an antenna

• Tuning an antenna to resonance

• Comparing characteristics of an antenna before and after specific event (rain, hurricane, etc.)

• Making coaxial stubs or measuring their parameters

• Cable testing and fault location, measuring cable loss and characteristic impedance

• Measuring capacitance or inductance of reactive loads

AA-230 ZOOM Calibration

Although RigExpert AA-230 ZOOM is designed for high performance without any calibration, an open-short-load calibration may be applied for better precision.

The standards used for calibration should be of high quality. This requirement is especially important for high frequencies (100 MHz and upper). Three different calibration standards should be used: an «open», a «short» and a «load» (usually, a 50-Ohm resistor). A place where these standards are connected during calibration is called a reference plane. If the calibration is done at the far end of a transmission line, parameters of this line will be subtracted from measurement results and the analyzer will display «true» parameters of a load.
