Chapter 1
General Information
1-1 Scope of Manual This manual provides general information, installation, and operating
information for the Anritsu series MG369XB synthesized signal gener-
ator. Throughout this manual, the terms MG369XB,signal generator,
and synthesizer will be used interchangeably to refer to the instru-
ment. Manual organization is shown in the table of contents.
1-2 Introduction This chapter contains general information about the series MG369XB
signal generators. It includes a general description of the instrument
and information on its identification number, related manuals, options,
and performance specifications. A listing of recommended test equip-
ment is also provided.
1-3 Description The series MG369XB synthesized signal generators are microproces-
sor-based, synthesized signal sources with high resolution phase-lock
capability. They generate both discrete CW frequencies and broad (full
range) and narrow band step sweeps across the frequency range of
2 GHz to 67 GHz. Options are available to extend the low end of the
frequency range to 0.1 Hz. All functions of the signal generator are
fully controllable locally from the front panel or remotely (except for
power on/standby) via the IEEE-488 General Purpose Interface Bus
(GPIB). Table 1-1, page 1-5, lists models, frequency ranges, and maxi-
mum leveled output.
1-4 Identification
Number All Anritsu instruments are assigned a unique six-digit ID number,
such as “020312”. The ID number is imprinted on a decal that is af-
fixed to the rear panel of the unit. Special-order instrument configura-
tions also have an additional specials number tag attached to the rear
panel of the unit, such as SM1234.
When ordering parts or corresponding with Anritsu Customer Service,
please use the correct serial number with reference to the specific in-
strument's model number (for example, model MG3693B synthesized
signal generator, serial number: 020312).

face Bus (GPIB). It contains a general description of
the GPIB and bus data transfer and control func-
tions, a complete listing and description of all
MG369XB GPIB product specific commands, and
several programming examples. The Anritsu part
number for the GPIB programming manual is
10370-10366.
Maintenance
Manual The Series MG369XB Synthesized Signal Generator
Maintenance Manual supplies service information
for all models in the MG369XB series. The service
information includes functional circuit descriptions,
block diagrams, performance verification tests, cali-
bration procedures, troubleshooting data, and as-
sembly and component removal/replacement
procedures. The Anritsu part number for the main-
tenance manual is 10370-10367.
1-7 Options The series MG369XB synthesizer provides a wide array of instrument
configurations through a series of base model and option choices.
Table 1-1, on page 1-5, lists the available models with frequency
ranges. Refer to Appendix B, MG3690B RF/Microwave Signal
