13.23 DDR (option R&S RTP-K91/K93 )
Double Data Rate Type 3 (DDR3) and Double Data Rate 4 (DDR4 ) are type of Syn-
chronous Dynamic Random Access Memory (SDRAM). With option R&S RTP-K91 /
R&S RTP-K93 you can perform the following analysis on DDR3/ DDR4 data:
●
Decode the signal.
See:Chapter 13.23.1, "DDR configuration", on page 907
●
Create and analyze an eye diagram. This helps to separate the read and write
cycle.
See Chapter 13.23.4, "DDR eye diagram analysis", on page 915.
●
Together with the R&S ScopeSuite software you can perform a compliance test on
the signal.
For details refer to:
– "DDR3 Compliance Tests, Test Procedures Manual"
– "DDR4 Compliance Tests, Test Procedures Manual"
