Get a quote

Aaronia presents the SPECTRAN® V6 X: the world's first and only 6GHz USB spectrum analyzer with dual USB true I/Q streaming of up to 245MHz (via 2xUSB) instanta­neous bandwidth (complex I/Q). It offers an extremely small POI (Probability Of Intercept) of up to 10ns and thus captures even extremely short signals. Furthermore, the SPECTRAN V6 X integrates a vector signal generator/tracking generator with a modulation bandwidth of up to 120MHz.

The SPECTRAN V6 X is Aaronia's latest generation of high-performance real-time spectrum analyzers. With a sweep speed of over 1THz/s it sets new standards in the USB compact class. Any number of devices can be cascaded to achieve an even higher real-time bandwidth. Thus, by using only four SPECTRAN V6 X, a real-time bandwidth of 1GHz is already achieved!

The included software RTSA-Suite PRO is precisely tailored to the powerful and robust hardware and supports the use of multiple SPECTRAN V6 X. The stackable aluminum housing facilitates the parallel use of several units.

The SPECTRAN V6 X will initially be delivered in three versions: V6-RSA250X, V6-RSA500X and V6-RSA2000X - with a max. instanta­neous bandwidth (complex I/Q) of up to 245MHz (via 2xUSB). The analyzer is compatible to all common Aaronia antennas.

The high-quality black anodized housing is cut from a solid aluminium block. Thus the SPECTRAN V6 X achieves an optimal shielding and cooling for the internal components. At the same time, the housing construction ensures maximum robustness. The integrated fan is speed- and temperature-controlled and thus generates only minimal noise.

Depending on the version, the SPECTRAN V6 X has one or two USB 3.0 ports for data transfer. A further USB port can optionally be used as power supply. A 26,800 mAh power pack with the same form factor is available separately and allows operation without the strain on the laptop battery.

Omnidirectional Antennas
The OmniLOG series was developed as a cost-effective broadband antenna series for omni-directional measurements up to 8GHz. The antennas are small in size, cover frequencies from 300MHz up to 8GHz and have steady gain across the range. Compared to the HyperLOG series, the OmniLOG antennas enables the omni-directional measurement of field-strengths without having to point the antenna at the source. This allows for much faster threshold measurements.

RF over Fiber (Rx/Tx)
Cable damping is a thing of the past! Aaronia's RF over Fiber solution impresses with its extremely high dynamics and linear frequency response. This makes it possible for the first time to transmit RF signals quasi 1:1 via fiber optics. This allows cable lengths of up to 100km to be achieved. Additionally, a galvanic separation between transmitter and receiver is achieved. Also available as dual version (e.g. for use with SPECTRAN V6-RSA2000X). Automatically locking and stackable.

26800 mAh Power Pack
The Aaronia Powerbank with its 26800mAh allows a high runtime extension of the SPECTRAN V6 with a laptop. The battery of the laptop is conserved because the SPECTRAN V6 is only operated via the Powerbank. The Powerbank is specially designed for the SPECTRAN V6 and provides the required voltage and power, and up to two additional devices can be supplied via USB. Allows a runtime of the SPECTRAN V6 of up to 4-5 hours. Automatically locking and stackable.

RF Satellite Test Probe
The RF Satellite test probe allows direct measurement at the LNB output or at the satellite receiver. The measurement can be performed with simultaneous use of the connection, the probe offers two separate signal outputs for the connected spectrum analyzer as well as the receiver. This allows a signal evaluation and recording during normal operation. The built-in DC blocker suppresses DC voltage which would be dangerous for connected Spectrum Analyzers. The package includes the necessary cables (SMA to F adapter, 0.3m SMA cable, 1.5m F cable) for direct connection of the measuring device and the receiver.
