When measuring at high sample rates, a long record length/large memory is necessary to be able to record a complete signal in the acquisition buffer. Where most oscilloscopes have 2.5 kSamples or 100 kSamples memory, the MultiScope MS6 has 32 MSamples memory per channel, on all channels simultaneously. This gives the user 300 to 10000 times more memory. An advantage of a large memory is that once-only fast phenomena can be captured completely. For example complete serial communications, like CAN bus signals, can be measured all in one record to be reviewed and analyzed afterwards.
The large memory results in the advantage of a large dynamic range in the USB spectrum analyzer, which enables troubleshooting in the frequency domain. It also provides a very small bin width, resulting in very high frequency resolution in the frequency spectrum.
The unlimited superzoom feature of the MultiScope MS6 allows to zoom in to individual samples, no matter what record length is used.
Figure 1 shows the same signal four times with different zooming factors. The lower right graph shows just 300 ns of the total 300 ms, a zoom factor of 1 million and still provides enough detail for accurate signal analysis.
