Deembedding in realtime for fast results

The realtime deembedding of signal path characteristics is based on S-parameters. Users benefit from highest acquisition speed even with activated realtime deembedding and precise triggering on compensated signal events up to the full instrument bandwidth.

Caractéristiques & avantages

Deembedding in realtime for fast results

Traditional deembedding capabilities are extended with flexible filter structures directly after the A/D converters. This allows waveform correction in realtime. The advantages over deembedding the acquired waveform during postprocessing are the measurement speed and instrument responsiveness. In addition, triggering on corrected waveforms is possible.

**Realtime deembedding architecture** - The pictures shows how the signal shape changes over a lossy signal path. With realtime deembedding the original signal can be reconstructed.

Correction of cascaded signal paths

A cascade of signal path blocks can be defined for deembedding. The individual blocks are described by S-parameters that can be derived from simulation or measured with a vector network analyzer. The deembedding software automatically calculates the correction filter for the overall system response.

**Menu to build up the signal path** - The signal path can be described easily by graphically adding up blocks. Each block can be descibed by S-parameters.

Triggering on corrected signals

Users can trigger on corrected waveforms and focus on debugging the true device characteristics. The unique digital trigger system operates with the sampling points of the A/D converter and the realtime deembedding filters. The trigger evaluates the real device signal since the distortion effects of the measurement path have been removed.

**Correction of different cable length** - A diff. signal is measured using a 20cm and a 2m cable, resulting in different rise-time and skew. Deembedding ON corrects losses, rise-time and skew.

Full bandwidth for all trigger types

In addition to the edge trigger, advanced trigger types such as pulse width, runt and setup & hold work up to the full bandwidth of the R&S®RTP. This enables fast isolation of high-frequency signal components. The trigger sensitivity is adjustable from 0 to 5 div and the trigger resolution can be extended up to 16-bit with the high definition mode. Users can reliably trigger on even the smallest signal details.
