"DDR"
Transmits the baseband signal in double data rate mode from the DUT
to the R&S
EX-IQ-BOX or vice versa. The rising edge and the falling
edge of the clock signal trigger data transmission (double speed trans-
fer).
The signal transmission is also shown in the graph.
Example:
●
Parallel signal input in double data rate:
Fig. 7-9: User defined > Signal flow: I/Q IN parallel, double data rate
Direction = Receiver
Format
= Parallel
Data Rate = DDR
●
Serial signal input in double data rate:
Fig. 7-10: User defined > Signal flow: I/Q IN serial, double data rate
Direction = Receiver
Format
= Serial
Data Rate = DDR
Remote command:
Interleaving
Activates interleaving and selects the interleaving mode.
Depending on the interleaving settings, the baseband signal is either sent simultaneously
or in I/Q or Q/I order from the external device (DUT) to the R&S
EX-IQ-BOX or vice versa.
