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>.

l Use READ? or INITiate[:IMMediate] to start the measurement.
Examples
The following example configures the instrument for frequency measurements on channel 1 using default
parameters, makes two measurements, and then transfers the measurements to the instrument output
buffer.
CONF:FREQ
SAMP:COUN 2

Typical Response: +1.00230000000000E+007,+1.00170000000000E+007
The following example configures the instrument for 10-digit frequency measurements of an approx-
imately 250 MHz signal on channel 2, makes one measurement using an external trigger, and then trans-
fers the measurement to the instrument output buffer.
CONF:FREQ 250E6,1e-4,(@2)
