l The trigger count (TRIGger:COUNt) and sample count (SAMPle:COUNt) settings are ignored when mak-
ing continuous totalize measurements. Only one measurement will be made for each READ? or INITiate
[:IMMediate] command. Additionally, the moving average filter, statistics computation, and histogram
computation (see CALCulate subsystem) are disabled for continuous totalize since these computations
require more than one measurement to be useful.
l The trigger count (TRIGger:COUNt) and the SENSe:GATE subsystem are ignored when making
timestamp measurements. Only one trigger will be accepted. The measurements will start immediately
after a trigger and trigger delay.
l The instrument sets the measurement function to FREQuency after a Factory Reset (*RST command) or
an Instrument Preset (SYSTem:PRESet command).
Return Format
The query returns a string enclosed in double quotes. The short form of the function name is always
returned (e.g., "FREQ", "PER 2", "TOT", "NDUT:BURS").
Examples
The following example sets the function to measure frequency on channel 2 (double or single quotes are
allowed).
FUNC "FREQ 2" or FUNC 'FREQ 2'
The following example returns the function selected (the quotes are also returned).
