At a very competitive price, the RSA306B provides deep signal analysis and full-featured spectrum analysis.
The RSA306B drastically reduces the cost of instrument hardware by separating signal acquisition from measurement using a user's PC and a high-speed USB 3.0 interface.
Your laptop, tablet, or personal computer is used for data analysis, storage, and replay. Computer upgrades are made simple and IT administration problems are reduced when the PC is managed independently of the acquisition gear.
Operating range from 9 kHz to 6.2 GHz with 40 MHz acquisition bandwidth.
Seamless signal streaming and real-time capture powered by PC processing.
Hardware acquisition decoupled from software, simplifying upgrades.

The RSA306B covers an RF input frequency range from 9 kHz to 6.2 GHz with an instantaneous real-time acquisition bandwidth of 40 MHz.
It requires a PC running 64-bit Windows 10 or Windows 11 with an active USB 3.0 port. SignalVu-PC software requires at least 8 GB of RAM and 20 GB of free storage. An Intel Core i7 4th generation processor (or higher) is necessary to unlock complete real-time capabilities.
To continuously record and store streaming data, the connected PC must have a storage drive capable of maintaining a sustained write speed of at least 300 MB/sec.
The instrument protects up to ±40 VDC. The safe RF input threshold without damage is +23 dBm (continuous or peak) when reference levels are ≥ –10 dBm, and +15 dBm when reference levels are below –10 dBm.
The unit is extremely compact and lightweight, weighing only 750 g (1.65 lbs) with dimensions of 31.9 mm (H) x 190.5 mm (W) x 139.7 mm (D), making it ideal for field and lab deployments.
Yes, the RSA306B features an external reference input supporting 10 MHz ±10 Hz sinusoidal signals with input levels between -10 dBm and +10 dBm at 50 Ω impedance.
