Anritsu MG3710A VSG-Vector Signal Generator equipment
This page of equipments section of Test and Measurement World covers Anritsu MG3710A VSG (Vector Signal Generator). It mentions features,specifications and applications of Anritsu MG3710A VSG (Vector Signal Generator).
The Vector Signal Generator generates vector modulated signal as per standard requirement. The standard can be WLAN, GSM, WCDMA or LTE. It can provide output in the form of IQ signal or modulated RF signal.
There are two parts in VSG viz. baseband and RF. The baseband part takes binary data as input and produces IQ vector as output. The modules in the baseband part depends on physical layer specifications of respective standard. The RF part takes IQ vector as input and produces modulated RF as output. The RF carrier depends on the frequency requirements of the standard as per country wide allocations.
Features of Anritsu MG3710A VSG
Following are the silent features of Anritsu MG3710A VSG.
• Frequency range supports upto 6 GHz
• Supports two RF channel outputs
• Provides dual memory to load baseband waveforms from multiple standards
• Useful for Rx Tests such as sensitivity, adjacent channel selectivity,
intermodulation tests, receiver blocking tests etc.

Application Note of Anritsu MG3710A VSG
The figure-1 depicts typical measurement setup used for WCDMA ACLR test. ACLR stands for Adjacent Channel Leakage Ratio. As shown in the setup, two sources are configured viz. one for wanted signal and the other for interfering signal. Appropriate frequency spacing is choosen between the two as per requirement. Appropriate power level is set in both the VSGs. This test procedure is very helpful for WCDMA ACLR test for the receiver.
It is also useful to generate other standard compliant signals.
Benefits of using Anritsu MG3710A VSG
Following are the benefits of using Anritsu MG3710A VSG:
• It is useful to evaluate future complex wireless receivers.
• It can generate transmit test signal as per LTE advanced specifications for
intra-bands and inter-bands.
• Supports multiple standards in single unit which is useful for inter RAT handover and
other interference testing.
