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

Basic resolution for frequency and period average is 12 digits in 1s measuring time. Statistics resolution enhancement algorithm (smart mode) gives up to one extra result digit depending on input signal and measurement setting.
