Oscilloscope boosts bandwidth to 16 GHz
Rohde & Schwarz has expanded its high-performance RTP oscilloscope family in terms of both bandwidth, and functions for debugging and analysis.

The latest RTP134 with 13 GHz, and RTP164 with 16 GHz bandwidth, support four channels to 8 GHz, or two channels interleaved for the respective higher frequencies. For all RTP oscilloscope models, update options support bandwidth increases right up to 16 GHz.

The new 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 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.

Ideal for debugging high-speed differential signals and available for both data acquisition and trigger functions, the 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.

RTP users can now analyze high-speed serial signals at data rates up to 16 Gbps with the serial pattern trigger options 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. Eye diagrams for signal integrity debug, based on the embedded clock, for at-a-glance analysis with the fastest mask test or histogram function provide results within seconds.

The RTP supports debug and compliance test on DRAM memory interfaces using DDR4, DDR4L, and LPDDR4 with the new option RTP-K93. It combines multiple functions such as READ/WRITE decoding, up to four DDR eye displays and automated compliance testing in line with the appropriate JEDEC standards.
