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.
Data bits already looked up Data bits that will be looked up
Data bits being
looked up
Data bits already written after converted Data bits that will be written
afterconverted
Data bits about to
be written
Source data bit pattern
Destination data bit pattern
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.
