Antenna for RF measurements up to 8 GHz

22 November 2023 Telecoms, Datacoms, Wireless, IoT

Saelig Company has introduced the Aaronia IsoLOG 3D Mobile PRO three-axis testing antennas for RF measurements up to 8 GHz. 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 8 GHz.

The antenna offers a plug and play solution for 3D measurements in fast time frames. Lightweight, at only 350 g, and compact (31,75 x 7 x 7 cm), 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 to 3 GHz (9030 PRO), 9 kHz to 6 GHz (9060 PRO), and 9 kHz to 8 GHz (9080 PRO). Each antenna includes an internal, rechargeable battery offering an operating time of approximately six hours, but it may also be powered from an external DC source. Switchable integrated low-noise single or dual pre-amplifiers, with a gain of 15 dB each @ 2 GHz, allow the measurement of 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. The antenna’s built-in and adjustable ‘chopper’ function uses glitch-free RF switches to provide an automatic endless antenna rotation 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.
