Rohde & Schwarz RTM oscilloscopes lead in analysis of long signal sequences

Published: 11th November 2014

With the RTM-K15 history and segmented memory option, the RTM bench oscilloscope allows you to analyse longer signal sequences than is possible with any other instrument in this class.

The RTM automatically acquires only the relevant signal sequences and stores them in segmented memory. You can then use the oscilloscope's full functionality to analyse the acquired signals in detail.

RTM-K15 History and Segmented Memory Option

This option expands the maximum memory depth of the RTM oscilloscope to an unprecedented 460 Msample per channel. The segmented memory has a variable depth ranging from 10 ksample to 20 Msample, enabling acquisition of up to 45,000 individual waveform segments.

The RTM-K15 is of particular benefit when analysing protocol sequences and pulse packets that include long gaps. The RTM triggers on the relevant data; gaps are skipped so that they do not tie up valuable memory.

The timestamp function clearly indicates exactly when the waveforms were acquired. This function allows you, for example, to acquire I2C data packets over several minutes and then analyse this data later on. The ultra segmented mode allows a particularly fast rate of acquisition. The short blind time of only 5 µs allows users to trigger on and store signals that appear in quick succession. You can use this mode to ensure that data in serial protocol or pulse sequences isn’t lost. Parameters such as acquisition mode and segment length are simple to set. The option then automatically calculates how many segments are available. After signal acquisition, you can easily navigate through the acquired waveforms with the history function.

All the analysis functions offered by Rohde & Schwarz’s RTM oscilloscopes, including QuickMeas, mask tests and cursor measurements, can be used on each acquired segment while in the history and segmented memory mode. The R&S RTM-K15 history and segmented memory option is available now. For further information please call +44 (0)8453 62 63 65.

Real-Time vs. Sampling Oscilloscopes: What Are the Differences?

All modern oscilloscopes are categorized as digital storage oscilloscopes (DSO) which digitally sample, store, and display a signal to the user - but the technique for accomplishing this can vary from one scope to another. Two distinct categories you’ve probably heard about are real-time scopes and sampling scopes, each of which have advantages for specific applications. Understanding the differences between these two instruments can help determine which one is right for your use case.
