Loop Antennas A.H. Systems' designs, manufactures and delivers high performance Loop Antennas for a wide range of magnetic field testing. Whether used in a set to measure shielding effectiveness per MIL-STD 285 and NSA 65-6 or individually to satisfy specific requirements,
Passive Magnetic Loop Antennas Passive Magnetic Loop Antennas (Transmit / Receive) 0 - 300 MHz.
LAS1 - CISPR 15 Loop Antenna LAS1 is a f2m loop antenna for testing magnetic emission of fluorescent lamps in the bandwidth 9kHz - 30 MHz in accordance with specification CISPR 15 (EN 55015).
HM020 - Triple-Loop Antenna Fully automatic measurement of the magnetic field strength in the X, Y and Z planes of a centrally placed EUT; receiver / processor-controlled.
Ae30-300 - H-field active loop antenna The principle of operation is that an RF voltage appears across the terminals of a loop when it is placed in an electromagnetic field. This voltage is proportional to frequency for a given field strength. Therefore at Very Low Frequencies, the voltage is very small, and requires greater amplification.
Type HFDF - Vector Gun Direction Finding Antenna System Type HFDF active directional antenna system consists of a high gain RF amplifier coupled to a tunable Faraday shielded loop antenna. Several loop antenna assemblies are available to provide coverage of frequencies in the HF and low VHF spectrum
Planar Antenna Benetel's antenna designers specialize in the design of: * Microstrip Patch Antennas * Planar Inverted F Antennas (PIFAs) * Printed loop antennas for short range devices (SRD) These types of antennas are particularly suited to wireless products that require low cost and low profile solutions.
PS-500 - Near Field Probes The Com-Power PS-500 near field probe kit is used find the source of EMI radiation from products that fail EMC compliance testing. The cause of the the higher emissions must be investigated and fixed to make the product compliant. Finding the source of the emissions at the circuit level is not possible using an antenna. Near-field probes let you "sniff" around the circuits, cables, and enclosures to find the source. PS-500 has four probes. Three E-field probes and one H-Field Loop Probe.
1008 - Magnetic Immuity Test System The PMM 1008 is an integrated system for magnetic field immunity test according to IEC 1000-4-8 & EN 61000-4-8. The system is composed by PMM 1008/1 (programmable current generator) and a loop antenna that is available in different sizes to select according to the EUT dimensions.
Hum Eliminator - 2 Channel Hum Eliminator All four of our Hum Eliminator products use our custom Isolation Transformers to break loop antenna that causes ground hum and buzz. The Eliminator also converts back and forth between balanced and unbalanced connections and prevents the cable from acting as a antenna for noise
HM525 - Active H-Field Measurement Antenna The Active H-Field Measurement Antenna HM525 is a loop antenna. The voltage at its output is proportional to the amplitude of the alternating magnetic field applied. For overview measurements, the antenna can be operated in broadband mode in the total frequency range from 100 Hz to 30 MHz. To obtain maximum sensitivity, the antenna can be locally or remotely switched to the subrange mode. In this case the frequency range is divided into five subranges with different amplifier concepts in the active antenna part. For a functional check the antenna can be operated in the test mode. The antenna is individually calibrated by comparison and comes with a calibration report.
TG 20 / 50 - Portable Audio Frequency Transmitter Automatic or manual impedance matching Charging unit and battery are incorporated, battery or mains operation Continuous or impulse mode selectable Two output frequencies selectable Illuminated instrument with display of (I) out and (I) in, switchable Terminals are free from touch High output power, therefore application of twist method possible Socket for loop antenna on side panel
Antennas for EMC testing * Conventional log periodic types for OATS applications. * Miniature antennas for chamber and small enclosure applications. * Large loop antenna for EN55015 compliance testing.
PS-400 - Near Field Probes The Com-Power PS-400 near field probe kit is used find the source of EMI radiation from products that fail EMC compliance testing. The cause of the the higher emissions must be investigated and fixed to make the product compliant. Finding the source of the emissions at the circuit level is not possible using an antenna. Near-field probes let you "sniff" around the circuits, cables, and enclosures to find the source. The PS-400 Near field has three probes. Two E-Field probes and a H-Field Loop Probe.
