The SNF chamber testing facility at JEM Engineering provides fast results to government and commercial groups looking to collect 4 pi steradian data. The electronically scanned probes take in readings from a full 360 degree measurement plane and can perform tests over frequencies from 400 MHz to 6 GHz. The SNF test chamber can analyze radiation patterns, efficiency, average gain and human body interaction of wireless system antennas for AMP, PCS, GSM, Bluetooth, IEEE 802.11, GPS and others.
SNF Custom Test Chamber
The spherical chamber at the testing facility at JEM can be customized to work for any antenna. While existing structures are in place that work with testing for most antennae, JEM Engineering also works with customers to custom design fixtures that will work to test any type of device. We will even build a custom fixture for you, if needed. The JEM SNF Test Chamber can be used to test active devices, antennae with an amplifier or an attenuator, and even can be used to test a body worn or handheld device on a subject. Testing times will depend on the number of frequency points measured, but tests of even over 100 Frequency Points can be completed from measurement to data results in about 10 minutes.
Analyses For SNF Chamber Testing
Results from the Spherical Near-Field Antenna Test can be presented in a variety of data formats, making them usable for future testing simulations. The data export is in ASCII text format which can be used in most standard software packages (such as Excel), and data can be exported according to customer requirements. This data can be modeled in 3D or 2D Radiation Patterns, Swept Gain and Efficiency plots, or used in simulations. Data packages typically consist of one or some of the following:
- Full spherical E-Phi and E-Theta values at each frequency
- Maximum Gain measured – Polarization, Phase and Amplitude
- Efficiency in dB and %
- Axial Ratio
- Individual Phi and Theta cuts
JEM Engineering is prepared to handle sight sensitive and classified samples. The SNF testing range is in a building that can be isolated for classified samples, if requested.
