A.H. Systems SAS-510-2 Log Periodic Antenna INTRODUCTION The SAS-510-2 Log Periodic Antenna (also known as a log periodic dipole array) is a compact, lightweight antenna that has been designed to ensure maximum gain, low VSWR and high power handling capabilities. This compact design is an ideal solution for...
A.H. Systems SAS-510-2 Log Periodic Antenna INTENDED PURPOSES The log periodic antenna is intended for general laboratory use in a wide variety of industrial and scientific applications and has been designed to be used in the process of generating, controlling and measuring high levels of electromagnetic Radio Frequency (RF) energy.
A.H. Systems SAS-510-2 Log Periodic Antenna OPTIONAL EQUIPMENT The following is a recommend accessory list for the SAS-510-2 Log Periodic Antenna: CONNECTING ACCESSORIES: PAM-0202 This preamplifier has a broad frequency range and at least 30 dB of gain. An ideal solution for improving overall system sensitivity for various emissions testing requirements.
A.H. Systems SAS-510-2 Log Periodic Antenna OPERATING INSTRUCTIONS ASSEMBLY INSTRUCTIONS The SAS-510-2 Log Periodic Antenna is shipped fully assembled. If an optional Log Periodic Tripod mount (LPM-510) was purchased, that will also be pre- assembled and mounted to the antenna.

A.H. Systems SAS-510-2 Log Periodic Antenna EMISSIONS TESTING MEASUREMENT POINT: For 3 and 10 meter testing, the measurement is made from the center of the antenna radiating elements and is annotated by a measurement point sticker (per ANSI C63.5). IMMUNITY TESTING MEASUREMENT POINT: Measurement is made from the tip of the antenna and typically preformed at a 1 meter distance.
A.H. Systems SAS-510-2 Log Periodic Antenna OPERATING INSTRUCTIONS Once the antenna is mounted to a mast or tripod, connect an N-type coaxial cable from the antenna to a receiver or RF generator. The cable should be matched to 50 ohms, relatively low loss and adequately shielded against leakage such as RG-214/U or better.

ANNUAL CALIBRATION To ensure reliable and repeatable long-term performance, annual re-calibration of your antennas, preamplifiers and current probes by A.H. Systems experienced technicians is recommended. Our staff can calibrate almost any type or brand of antenna. It is always up to the user to determine the appropriate interval for calibration certification based on the requirements of the end users specific test/application.
