Oscilloscope range doubles maximum bandwidth to 16 GHz

Rohde & Schwarz has doubled the bandwidth of its RTP oscilloscope family in terms of both bandwidth and functions for debugging and analysis.
Rohde & Schwarz has doubled the bandwidth of its RTP oscilloscope family in terms of both bandwidth and functions for debugging and analysis.

The R&S RTP134 with 13 GHz, and R&S RTP164 with 16 GHz bandwidth, support four channels to 8 GHz, or two channels interleaved for the respective higher frequencies. For all R&S RTP models, update options support bandwidth increases right up to 16 GHz. The oscilloscope familiy is is aimed at automotive, aerospace and defense, industrial and telecommunications applications debugging embedded electronic designs including high-speed buses (such as USB, PCI Express, MIPI or DDR memory interfaces), multichannel RF interfaces (radio or radar),  complex power management units, and even simple control and programming buses such as I2C, and SPI. 

The compact multi-purpose lab instrument family is now scalable from the 4 GHz minimum up to the full 16 GHz bandwidth. It also adds debugging functions such as the high-speed serial pattern trigger using hardware-based clock-data-recovery (CDR) up to 16 Gbps, or the DDR4 signal integrity and compliance test. The oscilloscope family now also provides time domain reflection (TDR) and transmission (TDT) analysis to characterize and debug signal paths.

The RTP models support all functions already introduced for models up to 8 GHz, including the high acquisition and processing rate, and the realtime deembedding. The bandwidth of the industry-leading digital trigger is extended to 16 GHz to provide the highest precision for detecting very small and intermittent signals. The R&S RTP triggers on realtime deembedded signals and supports all trigger types including pulse width, setup and hold, or runt, up to the full instrument bandwidth. 

A new math module introduced directly after the realtime deembedding block supports addition or subtraction for any two signals, plus signal inversion and common mode operations. This allows users to analyse high-speed serial signals at data rates up to 16 Gbps with the serial pattern trigger options from the R&S RTP-K140/K141, which include hardware-based clock data recovery for extracting the embedded clock signal as trigger reference. The trigger supports bit patterns up to 160 bits in length, plus decoding schemes such as 8B/10B, or 128B/132B.
