396/397 Getting Started Frequency Agility The Instrument generates its sample clock from a DDS circuit (direct digital synthesis). The DDS circuit enables frequency agility through the complete frequency range of the instrument. Having such an enormous range opens the door for a wide range of applications such as wide band sweep, FSK and frequency modulation. The Instrument can generate FSK, Ramped FSK and Linear or Logarithmic sweep. The Instrument can also frequency modulate its carrier using one of its built-in waveforms, or with any user- defined modulating signal, which can be downloaded using the FM wave composer. Multi-Instrument Synchronization There are applications requiring multiple of synchronized channels. Synchronization between completely independent, free-running units is complex. Besides distribution of the sample clock to all units, each unit has to be told when to start generating waveforms so that all start at the same point and with the same phase. Triggering multiple units to achieve synchronization is not enough because it will generate a jitter of ±1 count. Multiunit synchronization is built into the Instrument, where special connectors and cables were designed to eliminate jitter and to provide start phase control. There is no limit to the number of units that can be daisy-chained, multiple unit synchronization is built into each Instrument. Safety Considerations The Instrument has been manufactured according to international safety standards. The Instrument meets EN61010, VDE 0411/03.81 and UL 1244 standards for safety of commercial electronic measuring and test equipment for instruments with an exposed metal chassis that is directly connected to earth via the chassis power supply cable. WWarning To avoid personal injury from electrical shock and fire hazards, carefully read and follow the WARNINGS given in the following paragraphs. • Do not remove covers form the Instrument when operating it or when the power cord is connected to line power. • Do not operate the unit with power applied and protective covers removed unless you are qualified to service the product. • If you are qualified to service the product, read all of the calibration and maintenance procedures and heed all warnings to avoid “live” circuits points. If the Instrument exhibits any of the following conditions do not operate the Instrument: • Fails to operate satisfactorily • Shows visible damage • Has been stored under unfavorable conditions • Has sustained stress Before operating the Instrument check the following: • Instrument performance has been verified by qualified personnel. • The common connector on the power cord is connected to the neutral connection (ground) of the power outlet. Waveform Generators Supplied Accessories • The proper power cord is connected to the unit. Do not use a two- conductor extension cord or a three-prong to two-prong adapter. This will defeat the protective feature of the third conductor in the power cord. • The instrument is configured to operate on the voltage at the power source. See Installation Section. • The proper fuse is in place for the power source to operate. The correct fuse to use is: Littelfuse, Cat.No. 218500; T, 250VAC, 0.5A. • All other devices connected to or in proximity to this instrument are properly grounded or connected to the protective third-wire earth ground. Supplied Accessories The Instrument is supplied with this Getting Started Manual, a disk containing the Getting Started Manual and the Users Manual, and a disk containing a Windows. version of the ArbExplorer software. Specifications The Instrument specifications are listed in Appendix A of the Users Manual. These specifications are the performance standards or limits against which the instrument is tested. 396/397 Getting Started 6 ...
