What is Hi-Resolution Mode?

High Resolution mode can be used to remove high frequency noise and increase vertical resolution. It achieves this by increasing the number of effective bits per data to 12-bits through digital and bandwidth filters. The algorithm it uses to achieve the 12-bits of vertical resolution is:

             Pre-Filter
Over-Sample Average Data-Thinning Filter

Mixed Signal Oscilloscopes

A mixed signal oscilloscope is an instrument enabling the simultaneous, time correlated observations and analysis of analog with digital (logic) signals, to establish causal relationships between the various areas of a device's electronics. They are purpose-built tools for troubleshooting electrical anomalies, measuring parametric values, and monitoring cause and effect relationships between signals.
