Features & benefits

Signal analysis: quick results

See small signal details in the presence of large signals

The R&S®RTA4000 has a customized Rohde & Schwarz 10-bit A/D converter and is a four-fold 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 voltage across the switching device must be determined during the on/off times within the same acquisition.

Segmented memory

100 Mpoint standard and 200 Mpoint interleaved

The R&S®RTA4000 has top-class memory depth of 100 Mpoints per channel and 200 Mpoint in interleaved mode. This is ten times more than similar oscilloscopes in the same instrument class. Users can capture longer acquisition sequences even at high sampling rates for more analysis results, such as when examining transients in switched-mode power supplies.

**100 Msample standard memory** - Capture and analyze pulsed and burst signals over a long period with up to 200 Mpoint standard acquisition memory

Capture more time at full bandwidth

Segmented memory: 1000 Mpoint with history function

The R&S®RTA-K15 option with deep, segmented memory analyzes signal sequences over a long observation period. Protocol-based signals with communications gaps such as I²C or SPI can be captured over several seconds or minutes. The variable segment sizes enable optimal utilization of the 1000 Mpoint memory. In history mode, previous acquisitions in the maximum segmented memory depth of 1000 Mpoint can be used for further analysis.

**1000 Mpoint segmented memory** - Capture the longest time periods with top-class 1000 Mpoint memory

Logic analysis with the MSO option

16 additional digital channels

The R&S®RTA-B1 option turns every R&S®RTA4000 into an intuitive MSO with 16 additional digital channels. The oscilloscope captures and analyzes signals from the analog and digital components of an embedded design - synchronized and time correlated to each other. The delay between A/D converter input and output can be conveniently determined with cursor measurements.

**Four-bit DAC signal change.** - The R&S®RTA4000 captures and analyzes analog and digital signals that are synchronized and time-correlated with each other.

Waveform and pattern generator

Generate analog and digital stimuli

The R&S®RTA-B6 waveform and pattern generator for up to 50 Mbit/s can be used in educational settings and prototype hardware implementation. Apart from the common sine, square/pulse, ramp and noise waveforms, it outputs arbitrary waveforms and 4-bit signal patterns. Waveforms and patterns can be imported as CSV files or copied from oscilloscope waveforms. Predefined patterns include. I2C, SPI, UART and CAN/LIN.

Digital voltmeter

Measure and display electrical potential

The R&S®RTA4000 features a 3-digit voltmeter (DVM) and 6-digit frequency counter on each channel for simultaneous measurements. Standard measurement functions include DC, AC+DC (RMS) and AC (RMS).

**Digital voltmeter** - The 3-digit voltmeter measures and displays the electrical potential difference between two points in an electric circuit.

Frequency analysis mode

Difficult-to-find faults often result from the interaction between time and frequency signals. The R&S®RTA4000 FFT function is activated at the push of a button or by simply entering the center frequency and span. The high-performance FFT function in the R&S®RTA4000 oscilloscope can be used to analyze signals with up to 128k points. Other practical tools include cursor measurements and autoset in frequency domain.

**FFT of a square wave** - The high-performance FFT functionality analyzes signals up to 128k points.

Mask test mode

Mask tests quickly reveal whether a specific signal lies within defined tolerance limits. Masks assess the quality and stability of a DUT based on statistical pass/fail evaluations. Signal anomalies and unexpected results are quickly identified. When the mask is violated, the measurement stops. Each violation generates a pulse output at the AUX-OUT connector on the R&S®RTA4000. This pulse output can be used to trigger actions in the measurement setup.

**Mask test with result statistics** - The pass/fail evaluation assesses DUT quality and stability.

The best choice for power

See power signal details with up to 10-bit resolution

Even the smallest details of a high dynamic signal are important to power measurements. RDS (on) verification for a MOSFET is one example. The high ADC resolution of R&S®RTA4000 oscilloscopes increases vertical resolution up to 10 bits. Previously unseen signal details are revealed and measurable. The RDS(on) example shows how the slope of the drain-to-source-voltage can be measured while the switch is closed.
