Description

The R&S® RTM oscilloscopes with 200 MHz, 350 MHz, 500 MHz or 1 GHz bandwidth offer a maximum sampling rate of 5 Gsa/s and a maximum memory depth of 20 Msa. As a result, they can display signals accurately, right down to the details, as well as provide high time resolution, even for long sequences.

Besides the common measurement and analysis tools, Rohde & Schwarz RTM2104 oscilloscopes have special features that help users to achieve the desired results quickly during debugging and signal analysis. At the push of a button, the QuickMeas function graphically displays the key measurement values for the signal that is currently active and updates them continuously. Functions such as mask tests and video triggers are supplied as standard with the Rohde & Schwarz RTM2104.

As a true scope of the art, the Rohde & Schwarz RTM2104 meets the increased demands on bench oscilloscopes for the development, production and servicing of embedded hardware, providing time, frequency, protocol and logic analysis, plus a digital voltmeter in a single box:

Time analysis: high sensitivity of 1 mV/div to detect signals that would otherwise be lost in the noise
Frequency analysis: reliable fault detection with integrated FFT and spectrum analysis with spectrogram option
Logic analysis: 20 Msa with 5 Gsa/s for detailed analysis of digital signals
Protocol analysis: simple triggering and decoding of serial buses
Digital voltmeter/frequency counter: key signal parameters at a glance

Special Features

Signal details at the push of a button: QuickMeas

The QuickMeas function offered by the Rohde & Schwarz RTM2104 oscilloscopes is unique. At the push of a button, it displays the key measurement values for a currently active signal. The signal is also graphically displayed with continuously updated auxiliary lines and markers. In addition to the QuickMeas results, the oscilloscopes also provide customary automatic measurement functions such as measurement of peak-to-peak voltage and signal frequency. The results are presented in tabular form, with statistical evaluation if desired.

Settings in seconds: mask test

Mask tests quickly reveal whether a specific signal lies within defined tolerance limits and use statistical pass/fail evaluation to assess the quality and stability of a device under test. Signal anomalies and unexpected results are easy to identify by stopping the measurement if the mask is violated. The mask test function is a standard feature in Rohde & Schwarz RTM2104 oscilloscopes. It is easy to use and can be flexibly configured. A new mask can be created from a reference signal with just a few keystrokes. Existing masks can be loaded from the internal memory or from a USB flash drive. If an active mask is violated, various actions can be taken to ensure the optimum response.

Measurement results in detail: cursor functions

The Rohde & Schwarz RTM2104 offers additional functions beyond the standard horizontal and vertical cursor measurements. Users can easily apply measurements such as mean voltage, RMS value and a pulse counter to a specific section of the signal. At the push of a button, the “Set to Wave” function automatically assigns the cursors to the corresponding signals, eliminating the need for manual positioning.

Integrated: FFT analysis

The FFT function has a dedicated button and enables users to detect and analyze faults within a signal's spectrum. Rohde & Schwarz RTM2104 oscilloscopes simultaneously provide a spectral display of the signal and a time domain window for checking the sampling interval. The Autoset button is extremely convenient: when it is pressed, the instrument automatically selects the amplitude and frequency scaling that optimally matches the measured signal. The R&S®RTM-K18 option turns the Rohde & Schwarz RTM2104 into a spectrum analyzer with spectrogram function.

Digital voltmeter and frequency counter

With the R&S®RTM-K32 option, any channel can be used as a three-digit digital voltmeter (DVM) and as a seven-digit frequency counter. The measurement is performed regardless of the oscilloscope status, i.e. it will update even if the acquisition was stopped.

Low noise and low crosstalk

The accuracy of a signal displayed on the screen greatly depends on the oscilloscope's inherent noise. Rohde & Schwarz RTM2104 oscilloscopes have low-noise frontends and A/D converters, enabling them to measure precisely, even at the smallest vertical resolutions. This precision is retained even when additional channels are used. Rohde & Schwarz RTM2104 has an excellent channel-to-channel isolation of > 50 dB up to 500 MHz, which ensures that the signal from one channel has the lowest possible influence on signals from the other channels.

Deep memory: long sequences at high resolutions

The more details an oscilloscope can show, the higher the probability of detecting signal faults and important events. The oscilloscope must have a high time resolution, i.e. a high sampling rate. In addition, many applications require long acquisition periods, for instance for analyzing transients or serial protocols. This is where Rohde & Schwarz RTM2104 oscilloscopes excel. They offer a deep memory of 20 Msa at a time resolution of up to 200 ps (5 Gsa/s samplingrate). When combined with the R&S®RTM-K15 history and segmented memory option, the memory is expanded to 460 Msa.

Precision measurement: up to 5 Gsample/s sampling rate

The Rohde & Schwarz RTM2104 oscilloscopes' sampling rate of up to 5 Gsa/s makes it possible to accurately measure the timing of logic signals. Since the signals can be precisely time-referenced to one another, timing and clock errors can be detected with greater ease, e.g. on serial or parallel bus signals. Rohde & Schwarz RTM2104 oscilloscopes use the high sampling rate over the entire acquisition time, ensuring high time resolution even for long acquisition periods.

Tools for protocol analysis: triggering and decoding options

Serial bus signals include control, address and clock information in addition to the user data. Consequently, additional software support is typically required for debugging systems that use serial data buses. Isolating protocol-specific events becomes easier if the oscilloscope can trigger on the content of the serial protocol that is being used and display the decoded message. The Rohde & Schwarz RTM2104 provides versatile tools for protocol-specific triggering and decoding of serial interfaces. Extensive trigger capabilities help acquire relevant events. Because decoding is hardware-implemented, the Rohde & Schwarz RTM2104 enables smooth operation while quickly isolating faults.

Long acquisition periods with 460 Msample memory

The deep, segmented memory provided by the R&S®RTM-K15 option can be used for analyzing signal sequences over a long observation period with no signal-free gaps. For example, protocol-based signals such as I2C or SPI in embedded designs can be acquired over several seconds or minutes. Thanks to the variable segment size from 10 ksa to 20 Msa, the 460 Msa memory is optimally utilized; up to 45,000 cohesive individual recordings are possible. This feature will be appreciated by physics researchers who are monitoring pulsed lasers as well as developers of pulsed radar systems. When combined with the mixed signal option or serial bus analysis options, the R&S®RTM-K15 option is ideal for debugging embedded designs.

Spectrogram: display of frequency over time

A spectrogram displays the frequency over time in addition to the current spectrum. The magnitude can be color-coded for easy interpretation. Thanks to the high FFT rate, even fast frequency changes can be displayed. Together with the R&S®RTM-K15 history and segmented memory option, the spectrogram marker shows the time of the acquisition and makes it possible to load the corresponding time and frequency waveforms onto the screen. All Rohde & Schwarz RTM2104 tools are available for analyzing the loaded waveforms.
