For Measuring Signals of Digital Mobile Communication Systems in North America, Europe and Japan

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 de-

vices 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 ex-

tension 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-pro-

grammable 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 config-

uration 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).

Anritsu-developed DSP and ASIC technology is used in the

MG0310A to achieve superior waveform quality factor (ρ) and spuri-

ous emission characteristics. Channel multiplexed signals are sup-

ported for both forward and reverse links. With two MG0310A units

mounted in the MG3670C/3671B/3672A, all the test signals required

to conform to TIA/EIA/IS-95, -97, and -98 can be generated.

Simultaneous outputs from the rear extension connectors using long

and short codes, etc., support a wide range of applications including

RF related tests, IF stage performance tests, and device and mod-

ule quality evaluation. (Option 25 is required to install the MG0310A

in the MG3670B/3671A. The auxiliary signal output function is not in-

stalled, so long/short codes cannot be output.)

The MG0312A QPSK Modulation Unit generates QPSK/OQPSK

modulated I/Q baseband signals at 8 high-speed bit rates between

500 kbps and 2.4576 Mbps. Built-in modulation data includes PN7/

PN9/PN15/PN23 pseudorandom patterns. Use over a wide range is

supported by multiple baseband filters and the Phase Encoding func-

tion, which allows modulation data to be voluntarily phase mapped

onto a constellation. At the 2.4576 Mbps rate, the evaluation of trans-

mission section devices and modules can be performed such as RF

power amplifier for CDMA mobile stations.

The MG0314A Modulation Unit generates DS + QPSK modulated

(4.096/1.024 Mcps) I/Q baseband signals, supporting the W-CDMA

system specification. The various test signals required for W-CDMA

system experimentation can be generated by mounting the

MG0314A unit (it shares two slots) in the MG3672A.
