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. |
