:MEASure Commands

:MEASure:RISetime

Command Syntax
:MEASure: RISetime [<source>]
<source> ::= {CHANnel<n> | FUNCtion<m> | MATH<m> | WMEMory<r>}
<n> ::= 1 to (# analog channels) in NR1 format
<m> ::= 1 to (# math functions) in NR1 format
<r> ::= 1 to (# ref waveforms) 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.
This command is not available if the source is FFT (Fast Fourier Transform).
NOTE
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
