Designed with class-leading signal integrity and responsive ultra-deep memory, the R&S RTA4000 brings the power of 10 to a new level.A Rohde & Schwarz designed 10-bit ADC combined with class-leading low noise, memory depth and timebase accuracy gives you sharp waveforms, more accurate measurements and confidence when facing unexpected measurement challenges.

Traditionally, excellent signal integrity has been overlooked in the benchtop class of instruments because it is hard to accomplish and also expensive for instrument manufacturers. Users have had to compromise on measurement accuracy to get an affordable instrument that they could use for everyday debugging and troubleshooting tasks. With the R&S RTA4000, signal integrity was at the forefront when we designed it.

The 10-bit A/D converter yields up to a fourfold improvement over conventional 8-bit A/D converters. The class-leading low noise allows users to take advantage of this extra vertical resolution. You get sharper waveforms with signal details that would have been hidden on other scopes in this class.

Oscilloscopes in the R&S RTA4000 class have traditionally made users choose between deep memory and fast update rates. Each of these has its place, and having to choose one or the other means you may have the wrong tool for the problem you are addressing. The R&S RTA4000 doesn’t make you choose, it provides a fast update rate and ultra-deep memory to tackle any challenge that may come up.

The R&S RTA4000 is more than just an oscilloscope. It offers a logic analyzer, protocol analyzer, spectrum analyzer, waveform and pattern generator and digital voltmeter. A large, high-resolution capacitive touchscreen with a widely acclaimed user interface makes it easy to take advantage of all these tools.

Unrivaled signal integrity

10-bit ADC with up to 16-bit resolution

Rohde&Schwarz engineered a proprietary 10-bit A/D converter that delivers a fourfold improvement over conventional 8-bit A/D converters.

The increased resolution results in sharper waveforms with more signal details that would otherwise be missed. One example is the characterization of switched-mode power supplies. The voltages across the switching device must be determined during the on/off times within the same acquisition. For precise measurements of small voltage components, a high resolution of more than 8-bit is essential. With high resolution decimation, the R&S RTA4000 even provides up to 16-bit vertical resolution, a resolution previously unseen in this class of instrument.

500 μV/div: full measurement bandwidth

The R&S RTA4000 oscilloscope offers outstanding sensitivity down to 500 μV/div. Traditional oscilloscopes can only reach this level of input sensitivity by employing soft- ware-based magnification of larger settings or by limiting the bandwidth. The R&S RTA4000 oscilloscope shows the signal’s real sampling points over the full measurement bandwidth – even at 500 μV/div.

Class-leading low noise

Higher resolution is only beneficial if the extra bits are not consumed by the noise of the oscilloscope. The R&S RTA4000 has class-leading low noise that allows you to take advantage of the extra bits of resolution and see signals that are hidden in the noise of other scopes.

Capture more time at full bandwidth

Deep memory: standard 100 Msample per channel and 200 Msample interleaved
The R&S RTA4000 offers class-leading memory depth:100 Msample per channel, 200 Msample in interleaved mode. This is up to 10 times more than similar oscilloscopes in the same instrument class. Maintaining a fast sample rate is directly tied to acquisition memory. With its deep memory, the R&S RTA4000 captures longer periods of time at high sample rates, giving you extra insurance for unexpected project requirements.

Class-leading timebase accuracy
With a timebase accuracy of ±0.5 ppm, the R&S RTA4000 is 5 to 20 times better than other instruments in its class. An excellent timebase is important to ensure accurate measurements over long time captures.

Standard segmented memory: 1 Gsample
The standard segmented memory analyzes signal sequences over a long observation period. For example, protocol-based signals with communications gaps, such as I2C or SPI, can be captured over extended periods of time without wasting storage on idle time. Thanks to the variable segment size from 10 ksample to 200 Msample, the deep memory is optimally utilized, more than 87 000 cohesive individual segments are possible.

Standard history function

History mode is an always-on capability to view previous acquisitions up to the maximum segmented memory depth of 1 Gsample. For further analysis, the complete toolset can be applied to recorded segments. This includes, for example, mask tests, QuickMeas function and FFT.

The right probe for the best measurement – more than 30 dedicated probes

Extensive probe range for all measurement tasks

A complete portfolio of high-quality passive and active probes covers all measurement tasks. With an input impedance of 1 MΩ, the active probes put only a minimum load on a signal source’s operating point. The very large dynamic range, even at high frequencies, prevents signal distortion – for example: 60 V (Vpp) at 1 GHz for the active single-ended probes.

Complete portfolio for power measurements

The portfolio of dedicated probes for power measurements includes active and passive probes for the different voltage and current ranges – from μA to kA and from μV to kV. Dedicated power rail probes detect even small and sporadic distortions on DC power rails.

Micro button for convenient instrument control

The situation is all too familiar. You’ve carefully positioned the probe on the device under test and want to start the measurements – but you don’t have a free hand. The micro button on Rohde & Schwarz active probes solves this problem. It is conveniently situated on the probe tip, and you can assign it different functions, such as run/stop, autoset and adjust offset.

R&S ProbeMeter: integrated voltmeter for precise DC measurements

One connection lets you see the scope waveform and gives you access to a highly accurate voltmeter that shows the DC value regardless of other instrument settings.
