Chapter 1 General Information

1-1 Scope of Manual This manual provides general information,installation, and operating

information for the Anritsu series MG369XA synthesized signal gener ator. Throughout this manual, the terms MG369XA, 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 MG369XA

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 MG369XA 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 65 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 MG3693A synthesized signal generator, serial number: 020312).

Chapter 2 Installation

2-1 Introduction This chapter provides installation instructions for the series

MG369XA synthesized signal generator. It includes information on ini tial inspection,preparation for use, storage, reshipment,and General Purpose Interface Bus (GPIB) setup and interconnections.

2-2 Initial Inspection Inspect the shipping container for damage.If the shipping container or

cushioning material is damaged, retain until the contents of the ship ment have been checked against the packing list and the signal gener ator has been checked for mechanical and electrical operation.

If the shipment is incomplete or if the signal generator is damaged mechanically or electrically, notify your local sales representative or Anritsu Customer Service. If either the shipping container is damaged or the cushioning material shows signs of stress, notify the carrier as well as Anritsu. Keep the shipping materials for the carrier's inspection.

2-3 Preparation For Use Preparation for use consists of installing the instrument into a

suitable operating location and connecting the signal generator to a power source.The following paragraphs provide these procedures along with information about power requirements, warmup times,and the operating environment. Figure 2-1, on the following page, illustrates the basic outer dimensions of the instrument.

Installation Rack Mounting Kit Installation

2-4 Rack Mounting Kit

Installation

The rack mounting kit (Option 1A) contains a set of track slides (90° tilt capability),mounting ears, and front panel handles for mounting the signal generator in a standard equipment rack. The following pro cedure provides instructions for installing the rack mounting hard ware on to the instrument. The rack mounting kit (Option 1B) uses the same inner assembly without the slide.This procedure may also be used for installing the Option 1B rack mount assembly. Refer to Fig ures 2-3 and 2-4 during this procedure.

Preliminary Disconnect the power cord and any other cables

from the instrument.

Procedure Install the rack mounting hardware as follows:

Step 1. Using a Phillips screwdriver, remove the

screws and the front handle assemblies from the instrument. (For instruments not having front handles,remove the screws and the front top and bottom feet from the instrument.) Retain the screws.

Step 2. Remove the four feet from the rear of the

instrument. Retain the screws.

Power Requirements

Power Connection

The signal generator accepts 90 to 264 Vac, 48 to 440 Hz,single-phase power. Power consumption is 300 VA maximum.The signal generator is intended for Installation Category (Over Voltage Category) II.

To connect the MG369XA to the power source, plug the female end of the power cable into the input line voltage receptacle on the rear panel (Figure 2-2). Then plug the male end of the power cord into a three-wire power line outlet. Turn on the rear panel power switch.This automatically places the signal generator in operation (front panel OPERATE LED on).

CAUTION

Before installing the MG369XA in its operating environ

ment, ensure that all airflow passages at the sides and rear of the instrument are clear. This is of particular importance whenever the unit is being rack-mounted.

Keep the cooling fan filters clean so that the ventilation holes are not obstructed. A blocked fan filter can cause the instrument to overheat and shut down.

Standby Operation

Whenever the signal generator is not being used it should be left connected to the power source and placed in standby. This keeps the internal time base frequency reference at operating temperature.

On the front panel, press LINE to switch the MG369XA from OPERATE (green LED on) to STANDBY (orange LED on). (Hold the LINE key down for at least ½ second to prevent power-off of the unit.)

During standby operation, the fan runs continuously.

NOTE

Warmup Time

Operating Environment

From Standby–When placing the MG369XA in operation from standby, allow 30 minutes warmup to assure stable operation.

From a Cold Start (0°C)–The signal generator re quires approximately 120 hours (5 days) of warm up to achieve specified frequency stability with aging.

NOTE

Instruments disconnected from ac power for morethan 72 hours require 30 days to return to specified aging.

The MG369XA can be operated within the following environmental limits.

Temperature: 0°Cto50°C

Humidity: 5 to 95% relative at 40°C

Altitude: up to 4600 meters

Cooling: Internal cooling is provided by forced airflow from the fans mounted on the rear panel

GPIB Setup and Interconnection Installation

2-5 GPIB Setup and

Interconnection

The MG369XA provides automated microwave signal generation via the GPIB. The following paragraphs provide information about inter face connections, cable requirements, setting the GPIB operating pa rameters, and selecting the external interface language.

Interface Connector

Cable Length Restrictions

Interface between the signal generator and other de vices on the GPIB is via a 24-wire interface cable. This cable uses connector shells having two connec tor faces. These double-faced connectors allow for the parallel connection of two or more cables to a single device.

The GPIB can accommodate up to 15 instruments at any one time. To achieve design performance on the bus, proper timing and voltage level relationships must be maintained. If either the cable length be tween separate instruments or the cumulative cable length between all instruments is too long,the data and control lines cannot be driven properly and the system may fail to perform. Cable length restrictions are as follows:

q No more than 15 instruments may be installed

on the bus

Total cumulative cable length (in meters) may not exceed two times the number of bus instruments or 20 meters—whichever is less

NOTE

For low EMI applications, the GPIB cable should be a fully shielded type with wellgrounded metal-shell connectors.

GPIB Interconnection

The only interconnection required for GPIB opera tion is between the signal generator and the control ler. This interconnection is via a standard GPIB cable. The Anritsu part number for such a cable is 2100-1, -2, or -4 (1, 2, or 4 meters in length).
