Rohde & Schwarz announced enhancements to its oscilloscope portfolio with new models, applications, and accessories, and visitors to the company’s booth at embedded world 2015 in Nuremberg next month will have an opportunity to see the oscilloscopes on display for themselves, including a high-definition model with 16-bit vertical resolution.
The high-definition mode increases the vertical resolution of the R&S RTO and R&S RTE digital oscilloscopes to up to 16 bits—a 256-fold improvement over the 8-bit resolution available in standard mode. To achieve this higher resolution, the signal is lowpass-filtered directly after the A/D converter. The digital filter reduces the noise, while increasing the signal-to-noise ratio. The higher resolution leads to sharper waveforms, showing signal details that would otherwise be masked by noise.
Rohde & Schwarz also has added a new model with a 200-MHz bandwidth to its R&S RTM bench oscilloscope family. The history and segmented memory option, which expands the maximum memory depth to 460-Msample per channel, is available for all bandwidth models. This deep, segmented memory is beneficial for seamless analysis of data sequences with long rest periods such as pulsed signals and serial I2C bus data packets. The digital voltmeter option is also new. It enables the R&S RTM to measure various values such as AC, DC, peak, and crest factor with three-digit accuracy regardless of the oscilloscope’s triggering. The scope now features a seven-digit frequency counter as well.
New applications
The multiple triggering and decoding as well as compliance test options from Rohde & Schwarz support a broad range of users in design verification, commissioning, debugging, and compliance testing. The R&S RTE and R&S RTO oscilloscope series offer users in the automotive market triggering and decoding analysis solutions for the high speed CAN flexible data (CAN-FD) bus protocol. An option for the R&S RTO supports compliance tests of automotive BroadR-Reach Ethernet interfaces. For mobile communications and embedded designs, Rohde & Schwarz recently enhanced the capabilities of the R&S RTO by adding two new options for analyzing MIPI RFFE and USB 1.0/1.1/ 2.0 interfaces. Another innovation is the automated MIPI D-PHY compliance test option for developers of smartphone components and wireless devices with MIPI D PHY implementation.
The company will also highlight the entry-level R&S HMO1002 mixed-signal oscilloscope, which offers fanless operation, 1-Msample memory depth and a realtime sampling rate of 1-GS/s. It offers a vertical sensitivity of 1 mV/div and integrated 128k-point FFT. The R&S HMO1002 enables users to benefit from many practical features such as a pattern generator for embedded developers, an integrated digital voltmeter for service and maintenance technicians, and special functions for the education sector.
