The RSA306B: a new class of instrument
The RSA306B offers full featured spectrum analysis and deep signal analysis at a very attractive price. Using a fast USB3 interface and a user's computer, the RSA306B separates signal acquisition from measurement, dramatically lowering the cost of instrument hardware. The data analysis, storage, and replay is performed on your personal computer, tablet, or laptop. Managing the PC separately from the acquisition hardware makes computer upgrades easy, and minimizes IT management issues.
The RSA306B with SignalVu-PC offers basic and advanced measurements for field and lab
See what you've never seen before: The 40 MHz real time bandwidth of the RSA306B combined with the processing power of SignalVu-PC shows you every signal, even down to 15 μs in duration when a high-performance PC is used. The following image shows a WLAN transmission (green and orange), and the narrow signals that repeat across the screen are a Bluetooth access probe. The spectrogram (upper part of the screen) clearly separates these signals in time to show any signal collisions.
