Saelig has introduced the Aaronia IsoLOG 3D Mobile PRO Three-Axis Testing Antennas for RF measurements up to 8GHz.

The 3D Mobile PRO is an extremely 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 offers a plug-and-play solution for 3D measurements in fast time frames. Lightweight (350 g) and compact (12.5 x 2.75 2.75”), the IsoLOG3D Mobile PRO is a versatile, portable RF measurement tool. The antenna requires no software installation, no power connection, and no changes to hardware. It can be connected to any analyser or oscilloscope via its N (male or female) connector.

The IsoLOG 3D Mobile PRO is available in three different versions: 9 kHz - 3 GHz (9030 PRO), 9 kHz - 6 GHz (9060 PRO), 9 kHz - 8 GHz (9080 PRO). Each IsoLOG 3D Mobile PRO includes an internal, rechargeable battery offering an operating time of approximately 6 hours, but it may also be DC-powered. Switchable integrated low-noise single or dual pre-amplifiers (+15dB each @ 2GHz) allow 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 either via USB, or by manual selection, requiring no USB connection. The IsoLOG 3D Mobile PRO built-in, ultra-fast and adjustable “chopper” function uses glitch-free RF switches to provide an automatic endless antenna rotation/selection, with a switching duration of up to 50 kHz. This transforms the IsoLOG 3D Mobile PRO into a fully functional 3D antenna without the need for any USB software control.
