l The gate source (see SENSe:FREQuency:GATE:SOURCE) is set to TIME.

The counter uses the <expected> and <resolution> parameters to configure the setting for the
SENSe:FREQuency:GATE:TIME command. The table below shows the relationship between relative res-
olution and gate time in seconds, where relative resolution = <resolution> / <expected>.

Return Format
The query returns a single measurement. The format of the measurement is controlled by the FORMat
Subsystem commands.
Examples
The following example configures the instrument for average period measurements on channel 1 using
default parameters, makes one measurement, and then transfers the measurement to the instrument out-
put buffer.
MEAS:PER?
Typical Response: +1.00230000000000E-007
The following example configures the instrument for 4-digit average period measurements of an approx-
imately 250 MHz signal on channel 2, makes one measurement, and then transfers the measurement to
the instrument output buffer.
MEAS:PER? 4e-9,1e-12,(@2)
Typical Response: +4.03337934613473E-009
