Anritsu Corporation (President Hirokazu Hashimoto) started sales of its new MG3710A Vector Signal Generator.
It outputs the RF signals required by tests for evaluating the TRx characteristics of wireless communications used by mobile phone systems, wireless LANs, digital broadcast systems, automotive electronics, and narrowband public and industrial radio.
With this release, the developed MG3710A supports installation of two RF*1 signal output connectors in one unit, each outputting two types of modulation*2 signal simultaneously to provide up to four types of RF signals for testing. In other words, one MG3710A unit supports all the tests that used to require several expensive signal generators previously.
Mobile terminals are becoming increasingly multisystem, supporting multiple functions, such as ISDB-T, wireless LAN, etc., services as well as LTE and W-CDMA. Furthermore, addition of the LTE Advanced*3 standard with MIMO*4 technology to the next-generation LTE standard, requires new carrier aggregation functions speeding-up communication speeds by overlapping multiple carrier waves*5 in different frequency bands.
As a consequence, R&D and manufacturing of various wireless communications systems requires multiple test signals.
By developing the MG3710A outputting up to four different test RF signals from one unit, Anritsu is helping cut development and production costs for multisystem mobile terminals and base stations, amplifiers, and digital public and industrial radio systems.
Mobile phones are becoming multisystem with many functions built into the terminal, such as digital broadcast ISDB-T, wireless LAN, GPS, in addition to LTE and W-CDMA functions. Similarly, cell base stations are also becoming multisystem with support for LTE, W-CDMA, GSM, etc. Moreover, the new LTE Advanced standard with MIMO technology to increase transmission speeds by widening the frequency band by overlapping multiple carrier waves in different frequency bands requires carrier aggregation*6 functions.
Evaluation of these multisystems requires multiple test signals. Anritsu has developed the MG3710A Vector Signal Generator as the successor to its previous popular vector signal generators. Since the MG3710A can output up to four types of RF test signal simultaneously, it is the ideal solution for development and evaluation of next-generation multisystem mobile terminals and base-station infrastructure using the new LTE Advanced standard.
The MG3710A outputs RF test signals for wireless communications systems operating in the 100 kHz ~ 2.7 GHz, 100 kHz ~ 4 GHz, and 100 kHz ~ 6 GHz frequency bands, such as LTE, W-CDMA, GSM, and CDMA2000 mobile phones, wireless LANs, digital broadcast systems and narrowband public and industrial radio.
Two RF signal output connectors can be installed in one unit, each outputting two types of signal simultaneously to support output of up to four types of RF signal for use as a multiple test signal source.
■ Output Full Range of RF Test Signals
In addition to LTE, the MG3710A has a full range of standard built-in waveform patterns supporting 3G W-CDMA/HSPA and CDMA2000, 2G GSM and PDC, as well as wireless LAN, Bluetooth®, digital broadcast ISDB-T, etc. Test signals are output simply by selecting the required waveform pattern. Furthermore, any pattern can be generated using the separately licensed IQproducer software to output new RF test signals.
■ Support for MIMO and Carrier Aggregation Functions
HSPA and LTE terminals incorporate MIMO technology to increase communication speeds. The new LTE Advanced standard aims to achieve speeds of 1 GHz in the future and carrier aggregation functions are being developed as a key technology for this.
MIMO and carrier aggregation evaluations require multiple RF signals, which a single MG3710A unit can output at much lower cost than traditional signal generators.
■ Excellent All-round Usefulness
The MG3710A builds on the excellent basic performance of its predecessor MG3700A with improved ACLR*7 and SSB phase noise*8 performance. As a result, it outputs high-quality RF signals, making it the ideal test solution for wireless applications ranging from wideband mobile phone systems to narrowband communications systems, such as automotive electronics, digital public and industrial radio, etc.
■ Customized Testing
The MG3710A RF signal outputs and output frequencies can be customized to match the application. In addition, installing the BER*9 measurement and AWGN*10 generation options tailors the configuration to any application.

*1 RF: Radio Frequency
Frequencies in the electromagnetic spectrum used by wireless signals
Wireless communication systems transfer information by converting it to electrical signals. The process of imposing the converted electrical signal on the carrier wave is called modulation.
*3 LTE Advanced
Fourth generation (4G) mobile communications standard approved by ITU. LTE Advanced aims to increase transmission speeds for the LTE standard now spreading worldwide to 1 Gbps when stationary and 100 Mbps when moving. Currently, 3GPP is deciding the international standard.
*4 MIMO: Multiple-Input Multiple-Output
Abbreviation for technology to widen data send and receive bands by combining multiple antennas
*5 Carrier Wave

*6 Carrier Aggregation
In mobile systems, increasing the bandwidth increases the amount of data transfer at high speed. Carrier aggregation is a technology for increasing the bandwidth by aggregating multiple carrier waves. Carriers with 10- and 20-MHz bands can use this technology to use the 30-MHz band to increase average and peak speeds.
