CONFigure:{FREQuency|PERiod} [{< range >|MIN|MAX|DEF} [, {< resolution >|MIN|MAX|DEF}]]
Sets all measurement and trigger parameters to their
urements. Also specifies the frequency or period range and resolution.
Parameter
<range>: 3 Hz to 300 kHz. Default: 20 Hz. (FREQuency)
<range>: 3.33 µs to 333.33 ms. Default: 50 ms
(PERiod).
<resolution>: See table below.
Specify <resolution> in the measurement's units (V, A, Hz, Ω, and
so on).
Configure frequency measurements using the default aperture and the 200 Hz (fast) AC filter. Then make
and read one measurement:
CONF:FREQ
FREQ:RANG:LOW 200
READ?
Typical Response: +1.32130000E+03
The 1 ms aperture applies only to the 34465A and 34470A.

The frequency or period < range > parameter is required only to specify the measurement resolution
l
parameter. It is not necessary to send a new command for each new frequency or period to be meas-
ured. The < range > and < resolution > parameters affect the aperture (gate time) as follows:
Resolution (34460A/61A)
Not Applicable
100 ppm × <range> (MAXimum) 10 ppm × <range> (DEFault)
10 ppm × <range> (DEFault)
1 ppm × <range> (MINimum)
The input signal for frequency or period measurements has an AC voltage component. Use

If the input voltage is too large for the selected voltage range (manual ranging), the instrument dis-
l
plays the word Overload on the front panel and returns "9.9E37" from the remote interface. Autor-
anging can be enabled for the input voltage.
Use READ? or INITiate
