Simplify DFS and DAA test signal creation  

Keysight Technologies, Inc. Signal Studio software is a flexible suite of signal-creation tools that will reduce the time you spend on signal simulation. For Dynamic Frequency Selection (DFS) profiles and Detect And Avoid (DAA) profiles, Signal Studio’s performance-optimized reference signals—validated by Keysight— enhance the characterization and verification of your devices. Through its application- specific user-interface you’ll create standards-based and custom signals for DFS or DAA tests. Signal Studio’s capabilities use waveform playback mode to create and customize the waveform files needed to test DFS for fixed wireless access (FWA) devices, or to test DAA for ultra-wide band (UWB) devices. Its user-friendly interface lets you configure signal parameters, calculate the resulting waveforms, and download files for playback.

Apply your signals in real-world testing  

Once you have set up your signals in Signal Studio, you can download them to a variety of Keysight instruments. Signal Studio software complements these platforms by providing a cost-effective way to tailor them to your test needs in design, development, and production test.

What is DFS (Dynamic Frequency Selection)  

Unlicensed devices, typically WLAN/WiMax™, are being allowed to operate in the same frequency spectrum that is currently allocated to licensed devices, typically radar systems (mainly for military & weather). Radar systems are guaranteed to have spectrum protection. Therefore, unlicensed devices must not transmit on the same frequency upon which a nearby radar system is operating. They must instead choose an operating channel that covers a frequency range not currently utilized by a nearby operational radar. This choice is made dynamically during operation and is called Dynamic Frequency Selection (DFS). Currently DFS is mainly defined in U-NII band, which is used primarily for WLAN systems, including three frequency bands: 5.150 to 5.350 GHz, 5.470 to 5.725 GHz, and 5.735 to 5.915 GHz.

DFS tests typically define the DFS profiles which describe the RF and time domain characteristics of a given DFS signal type. The DFS profiles are defined by various government communication agencies including FCC, ETSI, Japan MIC, Korea and China DFS standard.

DFS signal time domain characteristics include:  

• DFS pulse width (sec), pulse repetition frequency (Hz) or pulse repetition interval (sec)
• Number of pulses per DFS burst
• Number of DFS bursts

Frequency domain characteristics include:

• Burst center frequency (Hz) for a signal-burst profile which is fixed. For multi-burst frequency hopping profiles, this value changes from burst to burst
• Chirp bandwidth (Hz)--each pulse has a linear frequency modulated chirp between each bandwidth
