Key facts
The R&S®RTP-K140/141 options enable the high-speed serial pattern trigger function that can operate based on the extracted embedded clock of a serial signal. The R&S®RTP accomplishes this with hardware based clock data recovery (CDR) that supports a maximum nominal data rate of 8 Gbps or 16 Gbps, depending on the selected option.
The R&S®RTP-K140/141 options enable a hardware based clock data recovery (CDR) that supports a maximum nominal data rate of 8 Gbps or 16 Gbps, depending on the selected software option. The CDR can use any of the four analog input channels. This function can be added as an upgrade at any time since the options are license key enabled.
Setup of the hardware CDR
Selected from predefined setting for various standards or work with the custom mode
The high-speed serial pattern option of the R&S®RTP oscilloscope offers various trigger types:
Multiple pattern types
The RTPs serial pattern trigger support various pattern types including bit pattern sequences, PRBS errors or line codes such as 8b/10b and 128b/132b.
The R&S®RTP-K140/141 options support 8b/10b and 128b/132b symbols. The trigger aligns on specified words and triggers on a defined word sequence. This allows fast and easy debugging of protocol based highspeed interfaces such as USB or PCI Express.
8b/10b symbol trigger for USB3.1 Gen1
Trigger setup for USB3.1 Gen1 at 5 Gbps data rate. Alignment on a K28.5 word and a trigger condition consisting of five 8b/10b data words.
With the highspeed serial pattern trigger an data eye with the timing based on the embedded clock can be generated. For further signal integrity analysis, eye mask test and histogram functions are available.
Eye diagramm triggered by the CDR
Use the hardware CDR to generate eye diagrams for high-speed serial interfaces.
