The IsoLOG 3D is a plug-and-play solution enabling rapid 3D measurements, according to Aaronia.
German RF measurement specialist Aaronia has introduced a small isotropic antenna that is compatible with any spectrum analyser.
The IsoLOG 3D is a plug-and-play solution enabling rapid 3D measurements, according to the company. Because it works on the fly, the antenna doesn’t require any software installation, power connection or hardware changes. It is connectable via the N (male) connector to any analyser or oscilloscope.
The antenna has a frequency range of 9kHz to 3GHz or up to 6GHz, depending on the model. Its gain bypass mode is -42dB at 70MHz and -10dB at 3GHz, while its gain pre-amp on is -22dB at 70MHz and 10dB at 3GHz. Chop and switch speed rate ranges from 1Hz to 50kHz, while nominal impedance is 50 Ω.
Each IsoLOG 3D Mobile includes an internal, rechargeable battery, providing a run-time of six hours, and a switchable low noise bypass preamplifier. The integrated amp allows low-level signal measurements. When used in bypass mode, the antenna is capable for high field-strengths, according to the company. Control of the antenna is via USB; or via manual antenna selection mode, requiring no USB connection.
The antenna also features an adjustable "chopper" function, according to Aaronia. Using glitch-free RF switches this feature offers an automatic continuous antenna rotation/selection with a switching speed of up to 50kHz. This feature transforms the IsoLOG 3D Mobile into a fully functional 3D antenna without the need of any USB software control, according to the company.
The unit is shipped in a waterproof transport case and comes with a pistol grip with tripod functionality.
