Three oscilloscope series, the R&S RTC1000, R&S RTM3000 and R&S RTA4000 will be debuted by Rohde & Schwarz at embedded world 2018 in Nuremberg (February 27-March 1). These oscilloscopes are equipped with cutting-edge technology, a smartphone-like touchscreen and many more features.

Together with the R&S RTB2000 oscilloscopes introduced in 2017, Rohde & Schwarz now offers instruments in the 1000, 2000, 3000 and 4000 class.

The R&S RTM3000 oscilloscopes are designed for DC power and voltage measurements like ripple and noise measurements. The oscilloscopes feature a 10-bit vertical resolution and a vertical range up to 500µV/div with full bandwidth.

In addition, the 80 Msample memory depth allows measurements over long time periods with high sampling rates.

The R&S RTA4000 oscilloscopes have an even larger memory of 100Msample per channel, making them ideal for analysing serial protocols and power-on/off sequences.

They offer a 1Gsample segmented acquisition memory and have a 10-bit resolution to clearly display fine details.

The cost-effective R&S RTC1000 is extremely compact and can be upgraded with numerous additional functions: eight-channel logic analyser, four-channel pattern generator, digital voltmeter, component tester, spectrum analyser, counter, and protocol analyser for I2C, SPI, UART/RS-232, CAN and LIN.

Users can expand the bandwidth from 50MHz to a maximum of 300MHz via software license – something no other device in this price class offers.

In addition to its oscilloscopes, Rohde & Schwarz will be demonstrating probes to meet current challenges in the field of power measurement.

A 1:1 power rail probe with 4GHz measurement bandwidth detects even the smallest coupled RF signals in sensitive embedded components used for mobile and IoT applications.

For this highly sensitive, very low-noise probe, a 6GHz model of the extremely powerful Windows-based R&S RTO2000 series of lab oscilloscopes is recommended.

Other probes on display include a probe for measuring battery life as well as new probes for power electronics measurements up to 6000V that offer a measurement bandwidth of up to 200MHz, a particularly high common mode rejection ratio (CMRR) and for this type of probes- the best DC measurement accuracy of 0.5%.

The R&S Scope Rider was developed for power electronics measurements in the field.

Since the fully insulated handheld oscilloscope meets measurement category CAT IV requirements, it can be used to perform measurements up to 600V at the source of low voltage installations.

Various functions can be added, such as a harmonic analyser for power supply quality. The R&S Scope Rider features a CAN/LIN trigger and decode option for users in the automotive industry.

Components in large-scale integrated designs are often sensitive to RF disturbance signals from neighbouring components.

EMC measurements are therefore imperative during development. Rohde & Schwarz presents a pre-compliance test setup for developers who only sporadically measure EMC to test their designs.

The solution is based on the economical R&S FPC1000 spectrum analyser and the very user-friendly R&S ELEKTRA EMC measurement software.
