:MEASure Commands 20

Keysight InfiniiVision DSOX1204A/G Oscilloscopes Programmer's Guide 377

:MEASure:RISetime

(see page 798)

Command Syntax

:MEASure: RISetime [<source>]

<source> ::= {CHANnel<n> | FUNCtion | MATH | WMEMory<r>}

<n> ::= 1 to (# analog channels) in NR1 format

<r> ::= 1-2 in NR1 format

The :MEASure:RISetime command installs a screen measurement and starts a

rise-time measurement. If the optional source parameter is specified, the current

source is modified.

Query Syntax

:MEASure: RISetime? [<source>]

The :MEASure:RISetime? query measures and outputs the rise time of the

displayed rising (positive-going) edge closest to the trigger reference. For

maximum measurement accuracy, set the sweep speed as fast as possible while

leaving the leading edge of the waveform on the display. The rise time is

determined by measuring the time at the lower threshold of the rising edge and

the time at the upper threshold of the rising edge, then calculating the rise time

with the following formula:

rise time = time at upper threshold - time at lower threshold

Return Format

<value> ::= rise time in seconds in NR3 format

NOTE

This command is not available if the source is FFT (Fast Fourier Transform).
