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

For improved output accuracy, Model 80 employs a built-in counter. This counter is incorporated in an internal loop which constantly monitors the output frequency. Even the slightest deviation from the programmed frequency is detected and corrected by the microprocessor circuit. Model 80 features self-calibration and self-diag-nostic functions that can be operated anytime from the front panel or GPIB command. The self-calibration function compares the output signal parameters to built-in interna
