The oscilloscope offers the functionality of eight T&M instruments – including protocol, logic, and spectrum analyzers and a data logger for long-term monitoring. This functionality makes the product outstanding for signal integrity measurements on serial buses, for example, said the company. The isolated oscilloscope permits differential measurements without extra equipment typically needed for serial protocols in automotive applications. This makes it less expensive than a test setup with a lab oscilloscope and differential probes. The portable oscilloscope also offers a set of analysis options for the automotive segment.

With the RTH-K9 CAN FD triggering and decoding option based on the RTH-K3 CAN triggering and decoding option, the user can also analyze CAN FD signals. At transmission rates of up to 15 Mbit/s, CAN FD is faster than the Classical CAN (up to 1 Mbit/s) and is gaining in importance.

The completely digital triggering and decoding unit operates at a sampling rate of 1,25 Gsample/s, irrespective of the analog or digital channel sampling rates used for signal acquisition. This makes it possible to decode serial protocols even when very slow time domain signals are displayed at the same time. At the press of a button, the R&S Scope Rider displays the analyzed protocol in table format together with additional protocol-specific information. Another benefit is the support of symbolic labels. Decoded control signals are displayed in plain text. The oscilloscope comes as a two- or four-channel instrument for bandwidths up to 500 MHz.
