#### Display modes

**Values/Statistics: **Numeric display of Measurement values or Statistics parameters with large digits. Values mode also display auxiliary parameter values (with less resolution).

**Time-line/Distribution:** All measurements are displayed graphically. Multi-channel graphs are colorcoded. Statistics values are also displayed beneath the graphs.

#### Resolution

Measure up to 4 input signals in parallel with 7 ps resolution per timestamp (Period single, Time Interval, Pulse width, Rise/Fall time, Duty cycle, TIE), or 12 digits/s (frequency and period average).

#### Smart Frequency/Period avg. calculation mode
