:MEASure:RISetime

(see page 530)

Command Syntax :MEASure: RISetime [<source>]

<source> ::= {CHANnel<n> FUNCtion MATH}

<n> ::= {1 2 3 4} for the four channel oscilloscope models <n> ::= {1 2} for the two channel oscilloscope models

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.

N O T E This command is not available if the source is FFT (Fast Fourier Transform).

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