MX370075A DFS (ETSI) Waveform Pattern Installing the MX370075A DFS (ETSI) Waveform Patterns option in the MG3710A Vector Signal Generator supports output of ETSI EN 301 893 DFS test signals. Output of complex combinations of pulse and chirp signals required to support DFS tests is made easy just by selecting combination files supplied with the MX370075A. DFS(ETSI) Waveform Pattern Install The main frame requires a license. The MX370075A supports ETSI EN 301 893 DFS test signals. One unit supports pulse and chirp signals. PC not required. Simply selecting prepared waveform pattern outputs various signals. Slide 2

What is a Combination file? Sequence Function: This standard function switches and outputs multiple waveform patterns continuously. Standards-compliant test signals can be created by combining complex patterns of pulse, chirp, and null signal waveforms. Clicking Sequence Restart on the right starts output of the DFS test signal according to the standards. Combination File: Users can output pulse and chirp signals for DFS tests easily just by selecting a combination file with this sequence information.

[Supplement] What is DFS: Dynamic Frequency Selection? ETSI EN 301 893 specifies use of frequency bands from 5.25 to 5.35 GHz and from 5.47 to 5.725 GHz, for the WLAN 5-GHz band. Since these are the same frequency bands as used by meteorological radar Note and marine radar, these pulse signals are obliged to use Dynamic Frequency Selection (DFS) technology. The 5.15 to 5.25-GHz band does not require DFS tests. Note: Weather radar locates precipitation by transmitting pulse bursts every second. Interference from wireless LAN can be mistaken for precipitation. Therefore, use DFS to confirm the absence of weather radar before starting operation. Slide 14
