CW Generators : Anritsu MG3672A

The MG3670B/C, MG3671A/B and MG3672A are digital modulation signal generators equipped with a high-performance quadrature modulator. They output the signals needed to develop, test, and evaluate digital mobile communications equipment and related devices with expansion units.

The MG3670B/C operates from 300 kHz to 2.25 MHz; the MG3671A/B and MG3672A operate 300 to 2.75 MHz. Both provide a stable and precise output as well as spectrum purity up to +13 dBm, even with modulation. In addition to testing receiver sensitivity and excess input, they can be used for testing IF stage performance and for evaluating device quality. A CMOS-level mode is provided for I/Q signal input. The input frequency band covers the CDMA spread spectrum band, expanding the range of applications.

The MG3670C/3671B/3672A can be expanded by rear panel extension connectors to use for auxiliary signal output functions special to communication system. MG3670B/C, MG3671A/B and MG3672A can be used in combination with up to eight modulation units and a burst function unit simultaneously.

The MG0301C/0302A/0305A/0307A/0311A modulation units have a continuous data generator capable of generating arbitrarily-programmable data signals and ITU-T specification PN9/15 stage PRBS signals. They also have band-limiting filters and can output I/Q baseband signals.

The MG0303A Burst Function Unit uses the frame and slot configuration stipulated by various communication systems and has a modulation pattern generator function and a function for ramp control of carrier burst signals. It can also handle data editing and scrambling.

The MG0310A Modulation Unit generates SS + QPSK/OQPSK modulated (1.2288 Mcps) I/Q baseband signals, supporting the CDMA system (TIA/EIA/IS-95) used in US Digital Cellular Systems and the US Personal Communications Service (PCS).
