WARRANTY

The JOHN FLUKE MFG. CO., INC warrants each instrument it manufactures to be free from defects in material and workmanship under normal use for 2 years from the date of purchase. This warranty extends only to the original purchaser. This warranty shall not apply to fuses, disposable batteries, or any product or parts that have been subject to misuse, neglect, accident, or abnormal conditions of operation.

In the event of failure of a product covered by this warranty, JOHN FLUKE MFG. CO., INC will repair and calibrate an instrument returned to an authorized Service Center within 2 years of the original purchase; provided the warrantor's examination discloses to its satisfaction that the product was defective. The warrantor may, at its option, replace the product in lieu of repair. With regard to any instrument returned within 2 years of the original purchase, said repairs or replacement will be made without charge. If the failure has been caused by misuse, neglect, accident, or abnormal conditions of operation, repairs will be billed at a nominal cost. In such case, an estimate will be submitted before work is stated if requested.

If any failure occurs, the following steps should be taken:

1.Notify the JOHN FLUKE MFG. CO., INC or nearest Service Center, giving full details of the difficulty. Include the model number, type number, and serial number.

On receipt of this information, service data or shipping instructions will be forwarded to you.

2.On receipt of the shipping instructions, forward the instrument, transportation prepaid.

Repairs will be made at the Service Center and the instrument will be returned prepaid.

SHIPPING TO MANUFACTURER FOR REPAIR OR ADJUSTMENT

All shipment of JOHN FLUKE MFG. CO., INC instruments should be shipped in the original packing carton (If available). If the original carton is not available, use any suitable container that is rigid and of adequate size. If a substitute container is used, the instrument should be wrapped in paper and surrounded with at least four inches of shock-absorbing material.

Introduction and Specifications

INTRODUCTION

1-1.

The 6080A/AN Synthesized RF Signal Generator (also referred to as the "signal generator") is a fully programmable, precision, synthesized signal generator. The 6080A/AN is designed for applications that require good modulation, frequency accuracy, and output level performance with excellent spectral purity. The signal generator is well suited for testing a wide variety of RF components and systems including filters, amplifiers, mixers, and radios, particularly off-channel radio testing.

Specifications of the 6080A/AN are provided at the end of this section. The salient features of the 6080A/AN are as follows:

• RF frequency range of 0.5 MHz to 1024 MHz in 1 Hz steps

RF level range of +13 to -137 dBm in 0.1 dB steps

Internal and External Modulation: AM, FM, and Pulse

Internal 10 Hz to 100 kHz Synthesized Sine Wave Modulation Oscillator

Fifty Storable and Recallable Memory Locations

Standard IEEE-488 (GPIB) Interface, complying with ANSI/IEEE Standards 488.1-1987 and 488.2-1987

Closed-case calibration capabilities for Frequency Reference, AM, FM, and Level.

UNPACKING THE SIGNAL GENERATOR

1-2.

The shipping container should include a 6080A/AN Synthesized RF Signal generator, an Operator Manual, a Service Manual, a line power cord and two BNC dust caps. Accessories ordered for the signal generator are shipped in a separate container.

Section 2, "Installation", gives instructions on inspecting the new signal generator and explains what to do if it arrives damaged. Reshipment information is also included.

INTRODUCTION AND SPECIFICATIONS

SAFETY

1-3.

This manual contains information, warnings, and cautions that should be followed to ensure safe operation and to maintain the generator in a safe condition.

The signal generator is designed primarily for indoor use and may be operated in temperatures from 0 to 50°C without degradation of its safety.

WARNING

TO AVOID ELECTRIC SHOCK, USE A POWER CORD THAT HAS A THREE-PRONG PLUG. IF THE PROPER POWER CORD IS NOT USED, THE 6080A/AN CASE CAN DEVELOP AN ELECTRICAL POTENTIAL ABOVE EARTH GROUND.

WARNING

PIVOTING MODULE INSTRUCTIONS

IF NECESSARY DURING REPAIRS, PIVOT THE TOP (SYNTHESIZER)

MODULE UP TO ALLOW ACCESS TO ALL PARTS OF THE SIGNAL

GENERATOR. THE MODULE IS HEAVY AND CARE SHOULD BE EXER-

CISED. THE GAS STRUT IS PROVIDED FOR PROTECTION. CHECK THE

CORRECT OPERATION OFTHE GAS STRUT BY NOTING THE RESISTANCE

TO RAPID CLOSING OF THE MODULE WHILE YOU FIRMLY GRASP THE

MODULE BY THE HANDLE.

OPENING AND CLOSING INSTRUCTIONS ARE GIVEN BELOW AND ARE

REPEATED ON THE DECAL ON THE TOP FRONT OF THE SYNTHESIZER

MODULE.

RAISING THE MODULE:

1.REMOVE THREE HOLD-DOWN SCREWS LOCATED ON THE SIDE RAILS.

2.GRASP THE HANDLE AND LIFT UP.

3.LOCK IN THE UP POSITION BY INSTALLING ONE SCREW IN THE PROTRUDING BOSS ON EACH SIDE RAIL.

LOWERING THE MODULE:

1.SUPPORT IN THE UP POSITION AND REMOVE TWO LOCK UP SCREWS.

2.GRASP THE HANDLE AND LOWER THE MODULE KEEPING YOUR HANDS CLEAR.

3.LOCK IN THE DOWN POSITION BY REINSTALLING THE THREE HOLD-DOWN SCREWS.
