A classic embedded design test case is to simultaneously observe both the analog signal at the A/D converter input and the digital signals at the output. Standard oscilloscopes with only analog channels cannot perform this task. The MSO option for the R&S RTO oscilloscope provides 16 digital logic channels while fully utilizing the benefits of the base unit for mixed signal analysis.

Munich, November 10, 2011 — In mid-2010, Rohde & Schwarz launched the R&S RTO high-performance oscilloscope. This instrument makes it easy for users to obtain accurate results quickly. A new function has now been added to significantly broaden the application range: A hardware option turns the R&S RTO into a mixed signal oscilloscope (MSO). In addition to the usual two or four analog channels, the oscilloscope now features 16 digital logic channels with 400 MHz input frequency. Equipped with the MSO option, the R&S RTO allows time correlation between the instrument's analog and digital sections.

In product development and during sophisticated service work, users perform measurements on the digital signal lines of parallel and serial interfaces. This includes, for example, the parallel interfaces of A/D or D/A converters, parallel buses such as PCI or DDR as well as serial buses such as I2C/SPI or LIN/CAN. For all these applications, the R&S RTO with MSO functionality offers a very high sampling rate (5 Gsample/s) over the entire 200 Msample memory depth. A maximum time resolution of 200 ps makes it possible to accurately analyze signal content and quality. Critical events such as narrow, widely separated signal faults can be reliably detected using the digital channels.

The option comes with hardware-based acquisition, trigger and processing units. Even when the digital channels are on, high acquisition rates of over 200,000 waveforms/second can be achieved. Rare events are detected quickly and reliably, and debugging is speeded up significantly. If system designs must be verified, the digital trigger ensures high precision and flexibility. A wide variety of trigger types helps to pinpoint errors reliably. The easy-to-understand operating concept of the R&S RTO allows users to quickly solve even complex measurement tasks on embedded designs with up to 16 digital channels.

The R&S RTO-B1 MSO option is now available from Rohde & Schwarz. For more information E-mail: press@rohde-schwarz.com for Europe or chris.petrole@rsa.rohde-schwarz.com for North America. You may also learn more at the company’s website by clicking the link below our logo on this page.
