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

The descriptions throughout this manual apply to both Models 396 and 397 unless specifically noted in the description as 396 or 397. Otherwise the descriptions refer to both products collectively as the Instrument. Description The 396 is a single-channel Arbitrary Waveform Generator, and the 397 is a dual-channel Waveform Generator. Both are high performance waveform generators that combine many functions and features in one small but powerful package. The ArbExplorer software supplied with the

or 600 . output from the main generator. It will provide up to 20 V p-p into a high- impedance load or 10 V p-p into a matched 50 . or 600 . load. It can tolerate a short circuit for 60 seconds. shx0005f.gif AUX OUT The AUX OUT socket provides a two-level TTL and CMOS compatible signal, synchronous with the signal from the MAIN OUT socket. shx0006f.gif The symmetry of the AUX OUT signal is the same as that set for the main output but you can adjust the phase relationship between MAIN OUT and AUX

A more common practice when mounting to a concrete pad is to use vibration isolatorsThe two most common types of vibration isolators are steel spring and elastomer padThe primary purpose of vibration isolators is to reduce the noise and vibration which! would be transmitted from the genset to the foundation or supporting structure. A simple and effective method of mounting and applying pad type isolators is to place! non.skidding type isolation pads directly between the sub.base and floorThe num

All heat loads have been taken into consideration in sizing air flowD. Gravity louvers face inward for air intake and outward for dischargeE. Where electrically operated ventilation devices are used, power must be present under all ! operating situations. Be certain these devices are on the emergency circuit The room in which the generator set is to be installed must have adequate air flow through it to! provide combustion air, and remove heat radiated from the engine, exhaust system and! genera
