Code Conversion

On the AWG610 Arbitrary Waveform Generator, it is possible to select the

coding system used when pattern strings are output. If the code will be affected

by the immediately preceding data, the data item just before the first item of data

will be calculated as 0. The following tables show the coding systems.

Using the code conversion table, bit pattern can be converted to another code.

Figure F–3 shows an image of how the code conversion table is used.

When the data bits being looked up are

patternĆmatched to the data bits specified by PAST,

CURRENT, NEXT and PAST OUTPUT, corresponding

output code is written to the destination.
