Vector Signal Generator Outputs Four Signals At Once

Anritsu-MG3710A-AAnritsu’s MG3710A family of vector signal generators can generate test signals for LTE, LTE Advanced, W-CDMA/HSPA, CDMA2000, GSM and PDC, as well as WLAN, Bluetooth, and ISDB-T. Three models make up the series, with frequency coverage from 100 kHz to 2.7 GHz, 4 GHz, or 6 GHz. The MG3710A has two separate RF outputs, each of which allows two modulation schemes to be selected simultaneously, so up to four different RF signals can be generated at one time. These multiple RF signals make the instrument well suited for testing MIMO and Carrier Aggregation, as well as multi-system devices and systems.  Features of the MG3710A include ACLR of -71 dBc, SSB phase noise of <-131 dBc/Hz (typical), wide vector modulation bandwidth of 120 MHz that can be extended to 160 MHz using an external IQ input, and absolute level accuracy of +/-0.5 dB. High power output of +23 dBm eliminates the need for an external amplifier, while also reducing the risk of damage to the DUT. Fast switching speed of <600 µs makes the MG3710A well suited for production test environments. Further improving test times is 4 GB memory per RF output, which allows multiple waveform data to be loaded for reduced reload and measurement times. Besides pre-installed waveform patterns, any pattern can be generated using the company’s IQproducer software. Base price of the MG3710A is $25,200.
