[attachment=20031]
standard gain horn antennas are linearly polarized and provide an efficient low cost means of making measurements. A-INFO's standard gain horn antenna can cover from 260MHz to 110GHz frequency range. These horns are ideally suited for EMI testing, direction finding, surveillance, antenna gain and pattern measurements and other applications.
Also we provide specific standard gain horn antennas according to customers' requirement.
Test reports are for reference only.
Calibration is a comparison between measurements – one of known magnitude or correctness made or set with one device and another measurement made in as similar a way as possible with a second device.
The device with the known or assigned correctness is called the standard. The second device is the unit under test, test instrument, or any of several other names for the device being calibrated.
Fixed Attenuators
Antenna Systems & Solutions, Inc. is pleased to provide the following Fixed Coaxial RF Attenuators
Definition of Terms
fixed attenuator
A device used to reduce power levels of a signal by a fixed amount with little or no reflections. The
output signal is attenuated relative to the input signal while the input and output impedance is
maintained close to 50 ohms (or 75 ohms) over the specified bandwidth. Hence, this device is often
used to improve interstage matching in a circuit.

• Balanced Line-Zin Input Impedance of Balanced-Pair Transmission Lines Terminated with a Load This program is a companion to Input_Zwhich deals with coaxial lines. The input impedance of a transmission line is often needed. Much experience is required just to guess what it might be. This program accurately calculates it ...
• Balanced Lines 4 Balanced, Twin-Conductor Transmission Lines, 20Hz to 1GHz This program analyses the performance of a variety of balanced lines from lines with very wide-spaced, large-diameter, bare conductors for power distribution, via HF ladder-line antenna feeders, to figure-of-8 and oval plastic-insulated types. There are also the various overhead open-wire and paper-insulated underground forms of construction used in telephone and digital networks. At the UHF end of the spectrum there are receiver input tuned lines 1 or 2 inches long. Large diameter tubes are used as tank circuits in high power VHF transmitters ...
