Saelig Company, Inc. now offers the Aaronia IsoLOG 3D Mobile PRO Three-Axis Testing Antennas for RF measurements up to 8GHz. The 3D Mobile PRO is an exceptionally light and small isotropic antenna, compatible with any spectrum analyser, for making X/Y/Z-axis RF measurements, or in chop-mode, to make rotating measurements around an X/Y/Z axis for frequencies up to 8GHz. Ready for rapid use, it provides a plug-and-play solution for 3D measurements in fast time frames. Lightweight (350g) and compact (12.5" x 2.75" 2.75"), the device is a versatile, portable RF measurement tool. The antenna needs no software installation, no power connection, and no changes to hardware. It can be connected to any analyser or oscilloscope through its N (male or female) connector.

The device is offered in three different versions: 9kHz-3GHz (9030 PRO), 9kHz-6GHz (9060 PRO), and 9kHz-8GHz (9080 PRO). Each device includes an internal, rechargeable battery delivering an operating time of approximately six hours, but it may also be DC-powered. Switchable integrated low-noise single or dual pre-amplifiers (+15dB each @ 2GHz) enable the measurement of even very weak signals, while in bypass mode, the antenna can take accurate measurements in high-field strength situations.

The antenna is controlled through USB or by manual selection, needing no USB connection. The built-in, ultra-fast and adjustable 'chopper' function utilises glitch-free RF switches to supply an automatic endless antenna rotation/selection, with a switching duration of up to 50kHz. This transforms the device into a fully functional 3D antenna without the necessity for any USB software control.
