Mobile WiMAX Signal Generator

Anritsu Vector Signal Generator Evaluates Mobile WiMAX MIMO RX

Other Topics: WiMAX Broadband Tier 1, Mobile WiMAX Chipsets

Anritsu Company
March 12, 2007

Richardson, TX -- Anritsu Company introduces MX370105A Mobile WiMAX IQproducer application software for its MG3700A Vector Signal Generator. When equipped with the MX370105A, Anritsu claims the MG3700A is the first vector signal generator that can be used by manufacturers to evaluate the performance of their Mobile WiMAX equipment based on the IEEE802.16e specifications.

Any Mobile WiMAX waveform pattern recommended by the IEEE802.16e standard, including WirelessMAN-OFDMA, MAC (Medium Access Control Layer) and PHY (physical), can be generated by the MX370105A. A benefit of the MX370105A is that it supports Mobile Certification Wave2 and MIMO (Multi Input Multi Output) waveform patterns, which are critical for evaluating downlink (RX) functions of Mobile WiMAX equipment. Previously, multiple instruments were required to evaluate MIMO functions.
 
 
Because the MX370105A, like all of Anritsu’s IQproducer solutions, is PC-application software with the same GUI as the MG3700A. The MG3700A outputs the modulation baseband and RF signals using the waveform patterns generated by the MX370105A. Users can set the zone/burst area and zoom in or out using basic mouse operations. Confirmation of the sub-channel MAP can be conducted easily. Optional built-in BER hardware supports measurements using the fixed patterns required by IEEE 802.16e that are not supported by other general-purpose BER test sets.

The MG3700A provides users with a single-instrument solution for analyzing signals of major wireless communication systems. In addition to Mobile WiMAX, it also outputs standards-based digital modulation signals for GSM/EDGE, W-CDMA, CDMA2000 1X/1xEV-DO, IEEE802.11a/b/g, and ISDB-T1segment/BS/CS/CATV. Popular systems such as GPS, Bluetooth, and WLAN are also supported by the MG3700A.

It has a built-in 160 MHz arbitrary waveform baseband generator to output digital modulation signals simply by selecting the relevant waveform pattern file. Additionally, the MG3700A’s two built-in memories support output of both the wanted waveform and the modulation interference waveform or AWGN, using one memory for testing RX characteristics. This eliminates the need for two expensive signal generators and increases the efficiency of performance tests for multi-system mobile terminals, modules, and devices.
