Product Description
The DG2020A is a portable digital data generator designed for high performance
and ease of use. The DG2020A is easy to use for testing and evaluating
semiconductors and logic circuits, which are continually becoming faster and
more complex.
The DG2020A provides high performance and a wide range of functions in a
compact package. Features include the following:
Maximum data rate of 200 MHz
64 K word pattern memory
Flexible sequence looping (which does the equivalent of over a billion word
patterns)
12 channels (with support for up to 36 channels by adding optional modules
in 12 channel increments)
100 ps timing skew adjustment function
Variable output levels (from –3 to +7 V)
Any memory size from 64 words to 64 K words can be used easily, with no
restrictions within that range. TTL output level and variable output level pods
can be selected as the data output pods. Both pod types support setting of their
output stages to a high-impedance state. Each module supports delays in 4 of its
12 channels with a 100 ps resolution variable delay time.
The DG2020A provides flexible data editing functions, including word and line
unit input and extended data creation functions. Also, the DG2020A provides a
rich set of functions required for system construction, such as a sequencing
function, a jump function using external input, and an inhibit function.
