No screen antenna radiation measurement system
The radiation field map of the wireless design product with antenna typically requires a test equipment rack, but this system does not require the radio darkroom as long as it can be carried out in a medium-sized room.
The radiation field diagram illustrates a specific antenna and its associated wireless circuit possible coverage, but it is difficult to generate such a field pattern. They are usually generated by test signal generators, receivers, broadband reception antennas, and many must-have test attachments such as turning turning them in tests. Another relatively common and inconvenient test system attachment is a dark room, which prevents radio frequency interference from the frequency band of interest.

RMS-0740 No screen Antenna Radiation Measurement System System provides all things measured by three-axis radiant field intensity outside the dark room. It is designed to be used in non-open room environments, which can be used to analyze wireless design integrated with an antenna, which provides 0.7-4 GHz precision radiation field map measurement in medium-size room.
The antenna field map is typically associated with the radiation electromagnetic energy of the transmit antenna, and the field pattern is also applied to the antenna performance characteristics of the reception mode. As shown in Figure RMS-0740 Measurement System Prepares radiation field graph measuring amount to the active measured object with the transmitter, but also selects an optional signal generator (or configuring a user's own signal generator) to analyze Passive wirelessly measured in the receiving mode.
Sum
Of its parts
Radiation field graph measuring system consists of several parts, a dual-channel receiver (with signal generator option), a bipolar antenna, a stepper motor turntable, software, and connection power supply and control lines for fixing the measured antennas. The USB cable connected to the computer. The system controls the rotation to rotate the measured, and the three-axis radiation field map is measured by one time each axis. If you need, you can use a stepping motor without the rotating dump.
The MEGIQ radiation measuring system without electric waves performs three-axis antenna radiation field map measurement measuring system to assemble an antenna to minimize reflection in compact measurement space. You can use without calibration, the system is designed to obtain precise results in normal test space, such as 4x4x3m. It can be used for smaller test spaces, but carefully placed some absorbing materials to achieve minimum reflection. Test systems can measure multiple frequencies at the same time, and optionally test signal sources can generate vertical or horizontal test signals for evaluating the measured objects in reception mode.
The height of the system measuring antenna can be set from 100-170 cm, measurement antenna, and receiver for measuring a measured distance from 0.8-3.0 m. The receiver is synchronously measured along harmonic radiation vertical and horizontal polarity, minimum measurement step length is 2 degrees. A narrow measuring antenna beam width and a narrowband test receiver bandwidth joint work is used for an effective non-shielded and non-electric wave darkroom measurement environment.
The system can provide a turntable of standard size 28-x28-cm for immobilization of 7.5 kg, or select 100-x50-cm heavy load tool for weight reaching 30 kg of tested objects. In the radiation field map measurement, the motor is in the middle of the motor to complete the rotation within 30s, but when there is a special radiation field map measurement, the turntable can also be rotated.
Enhanced
With software
The measurement software simplifies the measurement installation of the test system, providing turntable control functions, data storage, and processing, graphical and generated reports. It provides a 3D test result, through test antenna processing data collection
Software can generate standard radiation field graphs and calculations related to subject-related statistics, such as minimal, maximum and flat average, total radiation power (TRP), effective radiation power (ERP, IN DBM), antenna gain (in dbi) ), Antenna efficiency (in percent), field strength (IN DBμV / M),
. Each measurement point covers a scan of multiple frequencies, which allows multiple radiation field diagrams to measure multiple radiation fields during a single rotation sequence.
Radiation field maps often require shielding environment assistance, such as electric waves dark rooms or Fala, which is to consider investment costs. When space and funds are limited, the radiation field graph is measured, the compact RMS-0740 MEGIQ radiation measurement system provides a larger system and the accuracy of the measuring box. Finally, it covers most of the wireless frequency bandwidth.
