25 | Keysight | Infiniium DCA-X 86100D Wide-Bandwidth Oscilloscope Mainframe and Modules - Data Sheet

Measurements

The 86100D DCA-X features two user interfaces for optimum

ease-of-use. It includes the classic DCA interface for complete

backwards compatibility with earlier DCA mainframes. It also

includes the new FlexDCA interface that provides new measure-

ments and powerful analysis capability in a fully customizable

application.

The following measurements are available from the tool bar, as

well as the pull down menus. The available measurements depend

on the DCA-X operating mode.

Oscilloscope mode

– Time

Rise time, fall time, jitter RMS, jitter p-p, period, frequency,

+ pulse width, – pulse wWidth, duty cycle, delta time, [Tmax,

Tmin, Tedge—remote commands only]

– Amplitude

V base, V max, V min, V avg, OMA (optical modulation

amplitude)

Eye/mask mode
