INTRODijCTiON The 6060A/AN Synthesized Signal Generator (referred to as the Generator or instrument) is a fully-

20、programmable, precision, synthesized signal generator. In addition, an FM deviation meter is included. The Generator is designed for applications that require good modulation, frequency accuracy, and output level performance with moderate spectral purity. It is well suited for testing a wide variety

21、 of RF components and systems including filters, amplifiers, mixers, and radios, particularly on-channel radio testing. 1-2. UNPACKING THE GENERATOR This shipping container should include a 6060A/ AN Signal Generator, two Instruction Manuals, and a line power cord. Any accessories ordered for the Ge

22、nerator are shipped in a separate container. Section 2, Installation and Operation, gives instructions on inspecting your new Generator. Reshipment information is also included. 1-3. SAFETY This instruction manual contains information, warnings, and cautions that should be followed to ensure safe op

23、eration and to maintain the Generator in a safe condition. The Generator is designed primarily for indoor use, and it may be operated in temperatures from OC to 50C without degradation of its safety. WARNING TO AVOID ELECTRIC SHOCK, USE A POWER CORD THAT HAS A THREE- PRONG PLUG. IF YOU DO NOT USE A

Controller Functions The Controller microprocessor controls all operator interface functions, performs background operations such as status checks, and updates (strobes) the front panel

28、 displays. Whether you are using local control with the front panel. or remote control with the IEEE-488 Interface. the microprocessor provides self test and diagnostic capability. Economical instrument performance is achieved by using software compensation EPROMs and accuracy-enhancement circuitry.

29、 1-6. LOCAL CONTROL The value of the basic parameters of the Generator, i.e. amplitude. frequency. or modulation can be controlled in three ways: Direct numeric entry Incrementing or decrementing the bright digit Step-up or step-down entry where the step size can be operator programmed Other control

DISPLAY FIELD The programmed values of modulation, frequency, and amplitude are displayed in the three display fields. When in the deviation meter mode, the measured

31、 deviation, frequency, and detector status are displayed in the three display fields. 1-8. REMOTE-CONTROL PROGRAMMING The IEEE-488 Interface allows the Generator to be remotely controlled with any IEEE-488 bus controller. The instrument can also be used on the IEEE-488 bus without a controller in a

32、listen-only or talk-only mode by selecting the appropriate Generator rear panel IEEE-488 switch settings.
