Commands by Subsystem

:MEASure:FREQuency

Command Syntax
:MEASure:FREQuency [<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:FREQuency command installs a screen measurement and
starts a frequency measurement. If the optional source parameter is
specified, the current source is modified.
IF the edge on the screen closest to the trigger reference is rising:
THEN frequency = 1/(time at trailing rising edge - time at leading rising
edge)
ELSE frequency = 1/(time at trailing falling edge - time at leading falling
edge)
This command is not available if the source is FFT (Fast Fourier Transform).
N O T E
Query Syntax
:MEASure:FREQuency? [<source>]
The :MEASure:FREQuency? query measures and outputs the frequency of
the cycle on the screen closest to the trigger reference.
Return Format
<source><NL>
<source> ::= frequency in Hertz in NR3 format
