Of course, all this measurement power and capability could be easily lost with a complex operating system. This is where the R&S RTE digital oscilloscopes shine, with each 10.4-in. color touchscreen display serving as a control center and bringer of test results. With the touch of a finger, measurements can be defined, initiated, and completed, and results can be organized and presented on a full-color screen with 1024 × 768 pixel resolution. This fully customizable display even simplifies working with multiple waveform measurements, showing waveforms and measurements along the edge of the screen in the form of signal icons. These icons can be touched, dragged, and dropped onto the main screen at any time for a better view.

The SmartGrid function additionally allows a user to divide the display screen into several “subscreens,” to simultaneously show different waveforms and the results of different measurements. Coupled with the instruments’ “history mode,” which stores previous waveform data, an operator can analyze the background of a signal sequence in search of the source of a signal glitch or problem. A user can essentially operate with the equivalent of several oscilloscopes within this one compact housing, viewing and comparing multiple signals and measurements quickly and easily.

To further simplify measurements, the R&S RTE digital oscilloscopes include a “Quick Meas” function which provides push-button access to some of the more commonly used oscilloscope measurements. These include amplitude, overshoot, duty cycle, frequency, rise time, and fall time, for as many as eight measurements at a time.

In addition, a mask testing function allows users to draw a mask on the touch screen around a desired portion of a waveform, to define waveform and tolerance limits and perform as many as eight measurements at a time according to defined limits. Using just a few keystrokes, an operator can define a mask with as many as 16 segments, or build the mask from a reference signal. Mask segments can be loosely drawn on the display screen and later optimized for greater precision by using the mask test dialog box.

The R&S RTE digital oscilloscopes meld power, precision, and ease of use into packages with a laboratory’s worth of measurement capabilities. In support of the oscilloscopes, the firm offers a variety of options, including a power measurement option, option (B1) for the addition of 16 digital test channels that turns the oscilloscopes into mixed-signal analyzers (Fig. 2), where a logic button provides direct access to the digital channels. The company has developed a broad range of probes to address a variety of applications, usable across all of the firm’s different oscilloscope models.
