Electronic enthusiast network news: WLAN, also known as wireless local area network, is a system that uses radio frequency (Radio Frequency RF) technology to transmit data. In terms of image, that is, several wireless devices reach the interconnection through one or several base stations (commonly referred to as hotspots or APs), and an internal LAN can be formed through wireless connection, and files can be shared. If the base station can access the Internet, the local area network can Wireless devices can also share internet access.

Whether you are at the airport or in a coffee shop, reading emails and surfing the Internet has become a part of everyday life. WLAN technology is also integrated into mobile phones and PDAs, enabling users of these products to benefit from improved mobile data access.

In order to make this technology smooth and seamless, and has achieved the effect of “out of the box”, Anritsu provides you with a successful solution for related technology integration products to meet the daily office and business WLAN access needs of customers.

1. Universal multi-module integrated test platform: MT8870A

The MT8870A Universal Wireless Test Suite is Anritsu's test instrument designed for high-volume production testing of general-purpose cellular and short-range wireless technologies. A single MT8870A instrument host can contain up to four MU887000A TRX test modules (10 MHz to 6 GHz*1). Each module integrates a vector signal generator (VSA) and a vector signal analyzer (VSA) for performing DUT transmit and receive tests. The MT8870A contains the MU887000A test module, which can be used to control RF tests via an external PC.

*1 : The standard is up to 3.8 GHz.

Integrated platform can accommodate 4 test modules

Up to 4 measurement modules can be installed in a single host, and each module can be independently controlled. The four modules share the same power supply after installation; the base and internal bus interface help reduce infrastructure costs.

Simultaneous measurement of 4 devices, parallel measurement of multiple wireless technologies for one device

After installing 4 modules in the MT8870A, you can connect and measure 4 test devices in parallel at the same time. In addition, with the popularity of mobile communication devices such as smartphones and tablets, when multiple wireless technologies are required on a single device, different technologies can measure in parallel with up to four modules, which helps to reduce measurement time. , reduce the space occupied by the production line test equipment.

Standard 160 MHz measurement bandwidth

The MU887000A TRX test module comes standard with a 160 MHz wide bandwidth. The RF transmit/receive test of the latest WLAN standard 802.11ac wireless module can be performed with TX measurements and waveform permissions.

Support multiple wireless standards

The MU887000A TRX test module supports RF (PHY) transmit and receive testing for cellular wireless technologies (LTE, W-CDMA, GSM, etc.) and short-range wireless (WLAN and Bluetooth).

Supported systems: LTE-FDD, LTE-TDD, W-CDMA/HSPA, TD-SCDMA, GSM/EDGE, CDMA2000, 1xEVDO, WLAN 802.11ac, WLAN 802.11abgn, Bluetooth, FM, GPS, DVB-H, ISDB- T, ISDB-Tmm

Built-in audio analyzer and generator (optional)

The built-in audio analyzer and generator support stereo and mono, with digital and analog interfaces. It can reduce the equipment used in the production of wireless modules.

2. The market is only dedicated to 802.11 WLAN equipment tester: MT8860C

The Anritsu MT8860C is the only WLAN tester on the market that can test WLAN devices in both network and direct mode according to the IEEE 802.11 standard.

The MT8860C integrated tester is designed for testing 802.11 WLAN devices. The high-speed measurement solution offered by the tester is suitable for both production and design verification.

The MT8860C replaces existing test systems that typically require a power meter, spectrum analyzer, and Gold Radio (with an external attenuator). As a result, the MT8860C can be quickly integrated into the production line, providing a versatile solution for all WLAN chipsets, making maintenance and calibration easier. The MT8860C also reduces test system costs, increases production throughput and is the most flexible WLAN test solution.

The MT8860C offers two modes of operation: network mode and direct mode. The Network mode uses standard WLAN signaling and can be used to test the DUT's transmitters and receivers. In "direct" mode, the MT8860C can test the DUT receiver by generating and transmitting WLAN packets and testing the DUT transmitter with its built-in transmitter analyzer. In "direct" mode, the DUT must be controlled using the test mode software utility provided by the chipset vendor. The user interface operates through the provided LANLook software package. LANLook runs on a standard PC, the instrument configuration and results display interface is a traditional Windows® system interface, and the resulting display is clearly digital and graphical. LANLook communicates with the MT8860C via the GPIB interface.

3. Measurement speed top signal analyzer: MS2830A

The MS2830A is a mid-range, high-speed spectrum analyzer/signal analyzer. It has the best dynamic range (average noise level [DANL]: –153 dBm, third-order intermodulation distortion [TOI]: +15 dBm) and excellent ±0.3 dB (typ) total level accuracy due to Unique level calibration technology.

The MS2830A supports an optional Vector Signal Generator (VSG) and can be used as a reference source for component Tx feature testing or as a source for Rx feature testing. Installing the VSG option reduces investment costs and space. The IQproducer PC software generates waveform patterns for the VSG and supports a variety of communication formats, including LTE FDD, LTE TDD (TD-LTE), and Mobile WiMAX.

Analysis options up to 125 MHz can also be installed with a variety of measurement software tools that support PC-free modulation analysis for a variety of communication systems. For example, Tx feature/modulation analysis for LTE FDD BTS and Rx feature testing is supported after LTE downlink/uplink measurement software and LTE IQproducer LTE are installed. Tx feature/modulation analysis for LTE TDD (TD-LTE) and Rx feature testing is supported with LTE TDD downlink measurement software and LTE TDD IQproducer. Measurement software options support a variety of key wireless communication systems such as WLAN IEEE802.11a/11b/11g/11j/11n/11p/11ac, Mobile WiMAX, W-CDMA/HSPA/HSPA EvoluTIon, GSM/EDGE, TD-SCDMA CDMA2000/1xEV-DO and 3GPP LTE FDD, LTE-Advanced FDD and 3GPP LTE TDD (TD-LTE). In addition, there are some general analysis software tools for modulation analysis of multiple TDMA systems using BPSK, QPSK, O-QPSK, π/4 DPQPSK, 8PSK, 16QAM, 64QAM, 256QAM, 2FSK and 4FSK modulation methods. Combining these hardware and software options in a custom configuration provides the best solution for every need.
