:MEASure:PERiod
(see page 860)
Command Syntax
:MEASure:PERiod [<source>]
<source> ::= {<digital channels> | CHANnel<n> | FUNCtion | MATH
| WMEMory<r>}
<digital channels> ::= DIGital<d> for the MSO models
<n> ::= 1 to (# of analog channels) in NR1 format
<r> ::= 1-2 in NR1 format
<d> ::= 0 to (# digital channels - 1) 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.
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
