[SENSe:]{FREQuency|PERiod} Subsystem

This subsystem configures frequency and period measurements.

Command Summary

[SENSe:]{FREQuency|PERiod}:APERture {<seconds>|MIN|MAX|DEF}

[SENSe:]{FREQuency|PERiod}:NULL[:STATe] {ON|1|OFF|0}

[SENSe:]{FREQuency|PERiod}:NULL:VALue {<value>|MIN|MAX|DEF}

[SENSe:]{FREQuency|PERiod}:NULL:VALue:AUTO {ON|1|OFF|0}

[SENSe:]{FREQuency|PERiod}:RANGe:LOWer {<filter>|MIN|MAX|DEF}

[SENSe:]{FREQuency|PERiod}:VOLTage:RANGe {<range>|MIN|MAX|DEF}

[SENSe:]{FREQuency|PERiod}:VOLTage:RANGe:AUTO {OFF|ON|ONCE}

[SENSe:]{FREQuency|PERiod}:APERture {<seconds>|MIN|MAX|DEF}

[SENSe:]{FREQuency|PERiod}:APERture? [{MIN|MAX|DEF}]

Sets the aperture time (gate time) for frequency and period measurements.

This parameter is shared between frequency and period measurements. Setting or querying the

parameter with the FREQuency version of this command is identical to setting or querying it with the

PERiod version.

Parameter Typical Return

{10 ms|100 ms|1 s}, default 100 ms +1.00000000E-01

Configure frequency measurements using a 1 s aperture, make a measurement, and return the result:

CONF:FREQ

FREQ:APER 1

READ?

l The aperture for frequency and period measurements does not autorange.

l The measurement resolution is related to the aperture (gate time) as follows:

Resolution Aperture

100 ppm × <range> (MAXimum) 10 ms

10 ppm × <range> (DEFault) 100 ms

1 ppm × <range> (MINimum) 1 s

l This parameter is set to its default value after a Factory Reset (*RST) or Instrument Preset (SYSTem:PRESet).
