Software enables single-instrument WLAN measurement

Software for the Anritsu MS269xA and MS2830A series signal analyzers, as well as the MG3700A vector signal generator to create single-instrument solutions that support the IEEE802.11n/p/a/b/g/j wireless LAN (WLAN) standards.

With the software installed, the instruments provide developers of WLAN devices, modules and boards used in home entertainment and automobile onboard wireless systems with accurate solutions to verify design performance.
 
The WLAN measurement software allows the MS269xA and MS2830A to support EVM modulation analysis, which is required for evaluating the Tx characteristics of IEEE802.11n/p/a/b/g/j WLAN signals. The analyzers can also measure key characteristics, such as spectrum mask, spurious, and adjacent channel leakage power.

Templates and signal capture/replay functions make it simple to read graphically displayed measurement results and operation procedures, which make evaluating Tx characteristics at the R&D stage more efficient.
 
In addition, the signals required for evaluation of Rx characteristics can be outputted by installing the WLAN IQproducer in either the MS269xA or MS2830A, when the analyzers are configured with the optional vector signal generator. This capability allows engineers to more thoroughly verify WLAN equipment design. IQproducer can be operated using a simple GUI, making it easy to set the signal output conditions recommended by the WLAN standards.
 
Engineers can also evaluate the Rx characteristics of WLAN equipment with the MG3700A, when WLAN IQproducer is used. It also has an easy-to-use GUI that simplifies setting output signals that meet WLAN standards. The MG3700A has a built-in two-waveform addition function for outputting both the wanted and interference/AWGN signals from a single unit, eliminating the expense of the previously needed two signal generators.

The software extends the capabilities of the MS269xA series, MS2830A, and MG3700A. The MS269xA series supports a standard analysis bandwidth of 31.25 MHz that can be extended to 125 MHz with optional hardware. A patented calibration process that includes multi-point amplitude calibration and phase calibration results with an accuracy of ±0.5 dB across a 6 GHz span.

The MS2830A is a single instrument with measurement capability that previously required both a spectrum analyzer and a signal generator. It consumes ≤ 110 W and reduces CO2 emissions by 45 percent.
 
The MG3700A is a signal generator for outputting the digital modulation signals for all key mobile communications systems. The built-in arbitrary-waveform baseband generator outputs any digital modulation signal simply by selecting the waveform pattern file.
