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 Generator is used for controlling the Instrument and generating, editing and downloading waveforms from a remote computer. The following highlights the Instrument and the ArbExplorer features. Feature Highlights • 397 - Dual output configuration with independent waveform control • 397 - Tight phase offset control between channels (1 point resolution) • 14-bit vertical resolution • Nearly 19-bit offset resolution • 396 - 1 Meg memory depth • 397 - 4 Meg memory depth for each channel • Ultra fast waveform downloads using DMA • 125 MS/s sample clock frequency • 396 -100 MHz REAR-PANEL sinewave output • 397 - 125 MHz REAR-PANEL sinewave output • 1 ppm clock stability • Extremely low phase noise carrier • External amplitude modulation • Frequency agility: FSK, ramped FSK, sweep, FM • Trigger start phase control and breakpoints • Built-in standard waveforms • 396 - Sequence generator • 397 – Separate sequence generators for each channel • Multiple instrument synchronization with tight phase control • 396 - GPIB and RS232 Interfaces • 397 - GPIB, USB, and Ethernet Interfaces 396/397 Getting Started ArbExplorer Feature Highlights • 396 - Three powerful tools in one software package: complete Instrument control panel, Waveform composer and FM signal composer • 397 - Four powerful tools in one software package: complete Instrument control panel, Waveform, pulse, and FM signal composer • 397 - Detailed virtual front panels control all of the Instrument’s functions and modes • Wave composer generates, edits and downloads complex waveforms • FM wave composer generates and downloads complex modulating signals • 397 - Easy, onscreen generation of complex pulses using the pulse composer. • 396 - Automatic detection of active instruments • Equation editor generates waveforms from equations • SCPI command and response editor simulates ATE operation • Translates waveform coordinates from ASCII and other formats • Simplifies generation of complex sequences Features, Functions, and Options The following is a general description of the features, functions, and options available with the Instrument. Output Channels The 396 is a single channel arbitrary waveform generator. The 397 is a dual-channel waveform generator. Although the two channels share a single sample clock source, each channel can be controlled separately to generate different waveform, amplitude and waveforms sequence. Having a single sample clock source is an advantage in a dual-channel configuration because it allows tight control over inter- channel synchronization and leading edge start phase where the initial skew between the two channels is just a few nanoseconds. Output Functions The Instrument is completely digital. There are no analog functions resident in its hardware circuits. Data has to be downloaded to the Instrument for it to start generating waveforms. The Instrument can generate a few standard functions such as sine wave, triangular wave and square wave. Each time that a standard function is required, the Instrument calculates its coordinates and places them in the waveform memory. Therefore, every time a standard function is selected, minimal time is required for the controller to compute the function and load its data to the waveform memory. Frequency Waveform frequency is programmed with 7 digits on the 396 and 9 digits on t...
