GSM RF Interference Test System
Guangzhou Jumho Electric Co., Ltd.
Cell phones and other wireless devices radiate powerful electromagnetic fields that can cause interference and noise in microphone signals. The interference and noise is called RF interference, which is an unwanted “signal” that occurs at the same time and frequency as a data signal. The RF interference disrupts the flow of data and degrades quality-of-service. Jumho Electric provides a cost-effective RF interference test system for GSM interference level measurement of wireless microphone.

Antenna, Loop Sensor
EM-6873 | 20 Hz – 100 KHz
The EM-6873 Loop Sensor Antenna uses passive circuits to transform magnetic field components between 20 Hz – 100 kHz to an equivalent open circuit two-terminal voltage on the receiving instrument. Use of the conversion Factor Chart, supplied with each antenna, will yield the strength of the magnetic induction field referenced to a uniform field. The loop is electrostatically shielded and therefore is sensitive only to the magnetic component (B-field) of the electromagnetic fields.

EMF Measurements/EM Measurements/Electromagnetic Radiation
Holland Shielding Systems B.V.
Electromagnetic fields cause interference in electronic devices and may affect the health of people close to where the fields are generated. It is important to recognize this at an early stage in a construction process, for instance at a future construction location or while construction is already underway, so that budgets are not exceeded. By means of field-strength measurements one can chart the existing electromagnetic fields and radiation emitted by GSM, UMTS antennas and transformer spaces, to mention a few examples. These measurements can help determine the best location in the new building for rooms where sensitive measurements are to take place, e.g. in hospitals or nano laboratories. And last but not least, field-strength measurements can detect sources of interference and can be part of a scheduled check of existing screened spaces and Faraday cages.

L-Band
QuestTel''s Satellite L-Band optical fiber Transmitter/Receiver set offers high pefromance and cost effective alternative to conventional coaxial systems. The L-Band Transmitter and Receiver pair is used for transporting L-Band RF over fiber from the antenna to the satellite receiver. Additionally transmitter provides optional 13/18V LNB power as well as Automatic Gain Control (AGC) to manage RF input level. By transporting the L-Band RF over fiber this range can be extended from several hundred feet to over 80 miles. Since optical signal is not affected by electromagnetic field, the quality of your signal will always stay at the high level. Also this fiber solution is more cost effective than coaxial system, as well as more reliable and flexible.

Magnetic Resonance Instruments
Integrated Dynamics Engineering
MRI systems represent a significant investment. As magnetic resonance images can be distorted by electromagnetic fields, frequently the location is isolated by passive shielding to somewhat insulate the detectors from image distorting EMI. But for a fraction of the cost of the machine an active EMI compensation can fully protect the image from damaging fields generated by other electrical equipment, passing traffic, elevators or other nearby equipment.
