Word Size
Sets the word size resolution of a sample. If the word size is set to a value n, the I word
and the Q word use these n bits. The R&S
EX-IQ-BOX supports word sizes from 4 to 18
bits.
Remote command:
Word Alignment
Sets the alignment of the data bits on the data lines. Either the MSB or the LSB is mapped
firmly to one data line. Depending on the word size the equivalent bit moves to the appro-
priate data line.
Note:
●
This parameter applies to parallel data transmission.
●
Graphics in the dialog of the generators and in R&S
DigIConf show the presently set
word alignment in the "User Interface Bits Alignment" section.
"MSB"
The MSB (
M
ost
S
ignificant
B
it) is mapped firmly to the same data line
and the data line of the LSB varies in dependency of the word size.
Example:
●
Fig. 7-17: User defined > Word alignment MSB: I/Q parallel transmission, 5 bit,
bit order MSB
word size
= 5
word alignment = MSB
bit order
= MSB
●
Fig. 7-18: User defined > Word alignment: I/Q parallel transmission, 9 bit, bit
order MSB
word size
= 9
word alignment = MSB
bit order
= MSB
