Introduction
description of the features, functions, and options available with the
Model 2074.
The Model 2074 is a bench-top, 2U high, half rack wide, four-
channel synthesized Waveform Generator, a high performance
instrument that provides multiple and powerful functions in one
small package. The 2074 generates an array of standard
waveforms from a built-in waveform library as well as arbitrary,
sequenced and modulated waveforms. The generator outputs 16-bit
waveforms from two channels at up to 200 MS/s with different
waveform properties. The unique design provides increased
dynamic range and lower "noise floor" making it ideal for the
generation of multi-tone signals and I&Q modulation.
Sample rates up to 200 MS/s are available with memory size up to
2 Meg. All channels are synchronized to the same sampling clock
however, each channel can output a different waveform shape and
length and by designing waveforms with different length, each
channel can output different frequencies that are synchronized to
the same sample clock source.
Based entirely on digital design, the 2074 has no analog functions
resident in its hardware circuits and therefore, data has to be
downloaded to the instrument for it to start generating waveforms.
The instrument can compute and generate a number of standard
functions such as sine, square, triangle and others. Complex
waveforms can be computed in external utilities, converted to an
