Large memory of 32 MSamples per channel
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 WiFiScope WS5 has 32 MSamples memory per channel. 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.
The unlimited superzoom feature of the WiFiScope WS5 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 0.003 ms of the total 300 ms, a zoom factor of 100000 and still provides enough detail for accurate signal analysis.
