Commands by Subsystem

:MEASure:RISetime

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