The Cubic Model L1470-10 Arbitrary Waveform Generator (AWG) is a dual channel arbitrary waveform generator that includes two digital (TTL) channels and two analog channels. This provides dual channel capability for either TTL or analog signals as required. Optionally, a mode is available that allows a single channel to provide both TTL and analog outputs. This extended VME format, high performance unit finds uses as both a general laboratory test instrument and in the generation of complex radar and communications signals. Built in programmable clocks with continuously variable frequencies from 10 MHz to 120 MHz provide for high sample rates. Independent operation of all channels or synchronization of one or more channels is possible. Sample clock frequencies may be obtained that are lower than 10 MHz by the use of built in divider chains.

The AWG contains a daughter board connector that can be used for special functions or user required options.

In TTL mode the generator has a memory depth of 32k. Each of the 32k pulse descriptors (pulse width and interval between pulses) may be repeated as many as 64k times. This provides easy creation of complex pulse bursts. Sequences may be created that include one or more pulse descriptors and these sequences may be repeated up to 64k times. Sequences may be chained together to produce unique pulse patterns. Long pulses may be created by programming the pulse width and pulse interval to the same value and repeating this descriptor. Long intervals may be created by programming a 0 pulse width and a pulse interval and repeating that interval.

In the analog mode, up to 64k memory depth is available with each point being definable by the user. The amplitude of each point is a 10 bit binary word, therefore, 1024 individual amplitude points are available. Optional software is available that will provide the creation of standard waveforms including those replicating antenna scan patterns.
