The RTP134 and RTP164 support four channels to 8GHz, or two channels interleaved for the respective higher frequencies. For all R&S RTP models, update options support bandwidth increases right up to 16GHz.
The new models support all functions already introduced for models up to 8GHz, including the high acquisition and processing rate, and real-time de-embedding. The bandwidth of the digital trigger has been extended to 16GHz to provide greater precision for detecting very small and intermittent signals. The RTP triggers on real-time de-embedded signals and supports all trigger types including pulse width, setup and hold, or runt, up to the full instrument bandwidth.
These models are intended for debugging high-speed differential signals and provide both data acquisition and trigger functions. The new math module introduced directly after the real-time de-embedding block supports addition or subtraction for any two signals, plus signal inversion and common mode operations.
Users will be able to analyse high-speed serial signals at data rates up to 16Gbps 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 R&S 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.
The new I/Q mode option RTP-K11 converts modulated signals to I/Q data for analysis, saving acquisition memory, and extending the maximum acquisition time. The VSE vector signal explorer is intended for in-depth analysis of wideband radar signals, or demodulating wireless communication signals including 5G NR. The I/Q data can also be used with any suitable external tool for proprietary signal analysis.
The RTP now also provides all the functions required as a time domain reflection (TDR) and transmission (TDT) analysis system to characterise and debug signal paths, such as PCB traces, cables and connectors. The new RTP-K130 option combines the highly symmetrical differential pulse signals from the R&S RTP-B7 pulse source with the analogue input channels to provide TDT/TDR analysis for both single-ended and differential signals. The software guides the user through setup, calibration and measurement.
In terms of probes, the RT-ZM family of modular probes which features interchangeable probing tips and instantaneous mode switching, as well as excellent RF performance, has been extended to include the RT-ZM130 with 13GHz bandwidth, and the RT-ZM160 with 16GHz bandwidth.
The RTP high-performance oscilloscope is intended for 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. According to R&S, it is the only instrument on the market that compensates for transmission loss from the signal source to the oscilloscope in real time, so it remains extremely fast even with signal correction activated.
