Antenna Analyzer AIM B for sale
Antenna Analyzer AIM B for sale In good working order comes with all necessary load connector’s Pl259 and BNC adapters and more, plus instruction manual, Measurements from 0.1 to 170mhz, this analyzer does more than just antenna measurements please research it’s capabilities for more details of what it is capable of. This reputed to be one on the best Antenna Analyzer’s This new antenna analyzer measures the complex impedance (magnitude and phase) at each frequency of interest in the range of 0.1 to 170 MHz. A PC is used to calculate several parameters, including SWR, and plot the results. The test frequency is generated digitally and bandpass filters are used to reject stray signals (like broadcast stations) that are more than a few KHz from the operating frequency. A 12 bit analog to digital converter digitizes the raw data. This avoids non-linearities associated with diode detectors, and results in very good dynamic range and linearity for accurate magnitude and phase measurements. Impedance measurements can range up to 10K ohms. The true phase angle is measured, so inductive or capacitive reactance can be determined without ambiguity. The RF generator can also be used as a signal source for testing receivers. The frequency is very stable and it can be calibrated to WWV. The digitized data is sent to the PC via the RS232 port. Power for the analyzer can be obtained from a small DC power supply or a battery. With a laptop computer, the unit is quite portable and it can even be mounted up on a tower at the antenna feed point if desired, with power being supplied through the RS232 cable. The impedance at the antenna itself can be read with the AIMC located in the shack at the receiving/transmitting end of the coax. The cable can be any length. The cable's impedance and loss characteristics are determined by a simple calibration procedure and the antenna's impedance is plotted directly during the scan. There are no internal adjustments for calibration. The frequency range is continuous from 0.1 to 170 MHz Some of the parameters that are calculated by the PC include: • SWR referenced to any impedance • Resistance and reactance at the cable input • Resistance and reactance at the antenna terminals • Resistance and reactance of discrete components • Return loss • Reflection coefficient • Cable length • Cable impedance • Cable loss • Distance to fault (open or short) • Smith chart display • Band scan for interfering signals • Quartz crystal parameters The scan data can be saved to disk or printed to compare before and after results. It can also be imported in spreadsheet programs for further analysis. The program has been tested with Windows , ME, XP, Vista, Win 7 and Win 8.1. It does not require an installation procedure. (It will run directly from a CD, a floppy disk or a flash drive.) The display can be scaled for use on any size computer monitor. The unit of length used for input/output data can be selected as feet or meters. A USB port can be used for communication with an optional USB/RS232 adapter. Read more
