The recent popularity of smartphones, tablets, etc., has caused an exponential increase in WLAN traffic, resulting in demand for faster communications speeds to help reduce traffic congestion. Consequently, not only is use of frequency bands conventionally reserved for indoor traffic being investigated for outdoor traffic in the 5 GHz WLAN space, but also new 5 GHz band WLAN devices are being actively developed, promoting adoption of newer standards facilitating faster communications speeds. Since 5 GHz band WLAN devices can detect meteorological and marine radar, etc., systems using the 5.3 GHz/5.6 GHz bands, they require a built-in Dynamic Frequency Selection (DFS) function for suppressing signal collisions. Installing the MX370073B and MX370075A in the Vector Signal Generator MG3710E supports FCC, ETSI and Japan MIC standards-compliant test signals required by the DFS function test for WLAN devices to facilitate efficient development of 5 GHz band WLAN devices.
Device Under Test (DUT)
Wireless LAN access point, Wireless LAN adapter, etc.
DFS Tests
5-GHz band WLAN devices operate in the same frequency band as weather and marine-navigation radar. 5-GHz band WLAN devices require a built-in dynamic frequency selection (DFS) function to detect and avoid interference with these pulse signals. The DFS test confirms this function.
Features
-
Full support for all required test patterns
About 400 test patterns must be supported just for ETSI.
The MX370073B/MX370075A have all the waveform patterns required by the test, helping reduce the preparation burden.
-
Easy operation by just selecting and loading waveform patterns
Even inexperienced operators with little knowledge of the DFS test and equipment can run accurate tests efficiently.
-
Supports FCC, ETSI, Japan MIC standards
All key DFS test standards are covered.
Offers 5.3-GHz band waveform patterns adopted by Japan MIC standard in July 2019.
