Saelig Introduces Aaronia IsoLOG 3D Mobile PRO Three-Axis Testing Antenna For RF Measurements To 8GHz

Compatible with any spectrum analyzer, Mobile PRO antennas can be used for 3-axis radiation measurements to 8GHz.

Saelig Company, Inc. 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 analyzer, for making X/Y/Z-axis RF measurements, or in chop-mode, to make rotating measurements around an X/Y/Z axis, for frequenices 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 analyzer 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.
