keysight technologies signal studio for dfs radar profles N7607B technical overview
2 keysight signal studio software is a flexible suite of signal-creation tools that will reduce the time you spend on signal simulation. for dfs radar profiles, signal studios performance-optimized reference signalsvalidated by keysightenhance the characterization and verification of your devices. through its application-specific user-interface youll create standards-based and custom radar signals for dfs tests. dynamic frequency selection (dfs) test signal studios capabilities use waveform playback mode to create and customize the waveform files needed to test dfs. its user-friendly interface lets you configure signal parameters, calculate the resulting waveforms, and download files for play - back. applications: C create keysight validated and performance optimized dynamic frequency C selection (dfs) reference test signals, compliant with radar signals defined by fcc, etsi japan mic and korean standard C create short (type 0-4), long (type 5) and frequency hopping (type 6 ) radar profiles defined in fcc 06-96 and fcc-13-22 C create reference and type 1-6 radar profiles defined in etsi 301 893 version 1.7.1 C create fixed or variable type 1-6 radar profiles and hopping radar type 1-2 profiles defined in etsi 302 502 version 1.2.1 C randomize the radar parameter sets of each trial with the seed setting C adjust pulse width, pulse repetition interval, number of bursts, number of pulses, etc. within the range defined in the standard C save and recall the settings of the generated trial list table with all parameters for repeatability testing C accelerate the signal creation process with a user interface based on parameter - ized and graphical signal configuration and tree-style navigation 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 plat - forms by providing a cost-effective way to tailor them to your test needs in design, development and production test. vector signal generators C x-series: mxg and exg C psg C esg C first-generation mxg typical measurements test transmitters with dfs capability: C detection threshold C channel availability check C off-channel cac (channel availability check) C in-service monitoring C channel shutdown C non-occupancy perio d simplify dynamic frequency selection (dfs) radar profle creation
3 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 operat - ing. 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 radar profiles which describe the rf and time domain characteristics of a given radar signal type. the radar profiles are defined by various government communication agencies including fcc, etsi japan mic and korean dfs standard. radar signal time domain characteristics include: C radar pulse width (sec), pulse repetition frequency (hz) or pulse repetition interval (sec) C number of pulses per radar burst C number of radar bursts frequency domain characteristics include: C 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. C chirp bandwidth (hz)--each pulse has a linear frequency modulated chirp between each bandwidth dynamic frequency selection (dfs) overview figure 1. time domain view of a radar profle. figure 2. burst level of a radar profle.
4 N7607B signal studio for dfs radar profiles can help you create fcc part 15 sub part e (fcc 06-96 and fcc 13-22), etsi en 303 893 v1.7.1, etsi en 302 502 v1.2.1, japan mic and korean standard-compliant radar signals for dfs test, which can be used for r&d or performance test. N7607B provides a user-friendly interface to let you easily generate radar test signals with the following steps: 1. select dfs in the tree view. next, select radar profiles, and use the drop-down arrow to display a menu from which you can select the desired radar profile from fcc, etsi japan mic or korean standard. 2. select fcc in the tree view. next, select radar type, and use the drop-down arrow to display a menu from which you can select the desired type, for example, type 5. 3. select create trial list. a new window named radar profile display will be displayed as the bottom graph. 4. select download for each trial to generate and download the waveform to the signal generator for playback. the signal for each trial is unique as required by the standards. typical dfs measurements include the following tests: C dfs detection threshold C channel available check (cac) time C off-channel cac time C channel move time C channel closing transmission time C non-occupancy period dynamic frequency selection (dfs) test figure 4.
