These oscilloscopes are using original technology LeCroy XStream is protected by several patents.
The distinguishing feature of this architecture is that signal processing is implemented software-hardware method, as opposed to a purely hardware used Tektronix et al. But by creating special microcode being loaded into the cache of the first processor level and process information on the clock frequency of the processor (without resorting to RAM) achieved an amazing performance of the system, competing with purely hardware implementation, and sometimes outstripping the last (example in comparison with the TDS7104).
When carried out in the same manner and advanced measurement and mathematical functions, it becomes clear why the "mathematics" has no equal LeCroy.
But this means that the performance of the processor pipelines plays a crucial role, in contrast to other architectures, where the processor is only used for GUI.
Of course, all the advantages of this architecture is particularly pronounced in the case of measurement, statistics, FFT and other functions and operating with a large memory depth of the captured signal. However, in the graph you can see that even the most trivial task to display a small amount of signal, was accelerated (for example, from 4.41 ms to 3.16 ms, in mode 1 ns / div). It is interpolated by the sine.
Interpolation sin x/x:
Several smaller increment in case of linear interpolation (I quote below a table with the results of comparative tests with linear interpolation).
Linear interpolation:
Especially significant speed boost in the capture of signals with deep load fastest memory (10 MB) and computational operations (in the table below: measurement period, the measurement period + track).
MODES with measurements:
All tests was used the signal from the output of the calibration of the oscilloscope: meander, 1 B, 1 MHz.
Compared parameters - waveform update rate, which was controlled by the frequency of restarting the oscilloscope trigger.
