The largest display 25.7 cm (10.1") with the highest resolution of 1280 × 800 pixel in its class, a capacitive touchscreen to quickly navigate in pop-up menus and a touch function to easily adjust scaling, to zoom in or to move a waveform – works just like your smartphone.

The 10-bit A/D converter yields up to a four-fold improvement compared to conventional 8-bit A/D converters. You get sharper waveforms with more signal details.

10 Msample memory depth is available on each channel if all channels are active. When interleaved, 20 Msample are available. That is 10 times more than comparable oscilloscopes offer. This captures longer signal sequences for more analysis results.

The Rohde Schwarz RTB2K-204M gives users more than just an oscilloscope. It also has the capabilities for a logic analyzer, protocol analyzer, waveform and pattern generator and digital voltmeter. Dedicated operating modes for frequency analysis, mask tests and long data acquisitions are also integrated. Debugging all kinds of electronic systems is easy and efficient – and satisfies the all-important rule of investment protection at a very attractive price.

Special Features

Oscilloscope

With a sampling rate of up to 2.5 Gsample/s and a memory depth of up to 20 Msample, the Rohde Schwarz RTB2K-204M oscilloscope excels in its class. A waveform update rate of more than 50 000 waveforms/s ensures a responsive instrument that reliably catches signal faults. Included standard tools provide quick results, e.g. QuickMeas, mask tests, FFT, math, cursors and automatic measurements, mincluding statistics.

Logic analyzer

The Rohde Schwarz RTB-B1 option turns every Rohde Schwarz RTB2K-204M into an intuitive-to-use MSO with 16 additional digital channels. The oscilloscope captures and analyzes signals from analog and digital components of an embedded design – synchronously and timecorrelated to each other. For example, the delay between input and output of an A/D converter can conveniently be determined using the cursor measurements.

Protocol analyzer

Protocols such as I2C, SPI and CAN/LIN frequently transfer control messages between integrated circuits. The Rohde Schwarz RTB2K-204M has versatile options for protocol-specific triggering and decoding of serial interfaces. Selective acquisition and analysis of relevant events and data is possible. With the hardware-based implementation, smooth operation and a high update rate is ensured even for long acquisitions. This is advantageous, for example, to capture multiple packetized serial bus signals.

Waveform and pattern generator

The optional Rohde Schwarz RTB-B6 waveform and pattern generator up to 50 Mbit/s is useful for educational purposes and for implementing prototype hardware. 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. Before playing signals back, the user can preview them to quickly check signal correctness. Predefined patterns for e.g. I2C, SPI, UART and CAN/LIN can be used.

Digital voltmeter

The Rohde Schwarz RTB2K-204M features a three-digit voltmeter (DVM) and sixdigit frequency counter on each channel for simultaneous measurements. Measurement functions include DC, AC+DCRMS and ACRMS – included in scope of delivery.

Frequency analysis mode

Difficult-to-find faults often result from the interaction between time and frequency signals. The FFT function of the Rohde Schwarz RTB2K-204M is activated with the push on a button and by just entering center frequency and span. Due to the high-performance FFT functionality of the Rohde Schwarz RTB2K-204M oscilloscopes, signals can be analyzed with up to 128k point. Other practical tools include cursor measurements and autoset in frequency domain.

Mask test mode

Mask tests quickly reveal whether a specific signal lies within defined tolerance limits. By using statistical pass/fail evaluation, they assess quality and stability of a DUT. Signal anomalies and unexpected results are quickly identified. When the mask is violated, the measurement stops. Each violation can generate a pulse output at the AUX-OUT connector on the Rohde Schwarz RTB2K-204M. This pulse output can be used to trigger actions in the measurement setup.

History and segmented memory mode

The Rohde Schwarz RTB-K15 history function option increases the memory from 10 Msample to 160 Msample. Users scroll through past acquisitions and analyze the data using all of the oscilloscope tools, e.g. protocol decode and logic channels. Serial protocol and pulse sequences are recorded practically without interruptions.
