:MEASure Commands

:MEASure:PERiod

Command Syntax
:MEASure:PERiod [<source>]
<source> ::= {<digital channels> | CHANnel<n> | FUNCtion<m> | MATH<m>
<digital channels> ::= DIGital<d> for the MSO models
<d> ::= 0 to (# digital channels - 1) in NR1 format
<n> ::= 1 to (# of analog channels) in NR1 format
<m> ::= 1 to (# math functions) in NR1 format
<r> ::= 1 to (# ref waveforms) in NR1 format
The :MEASure:PERiod command installs a screen measurement and starts the
period 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:PERiod? [<source>]
The :MEASure:PERiod? query measures and outputs the period of the cycle closest
to the trigger reference on the screen. The period is measured at the midpoint of
the upper and lower thresholds.
IF the edge closest to the trigger reference on screen is rising:
THEN period = (time at trailing rising edge - time at leading rising edge)
ELSE period = (time at trailing falling edge - time at leading falling edge)
Return Format
<value><NL>
<value> ::= waveform period in seconds in NR3 format
