[SENSe:]{FREQuency|PERiod}

This subsystem configures frequency and period measurements.

Command Summary

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

[SENSe:]{FREQuency|PERiod}:NULL:VALue {<value>| minimum | maximum |

default}[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}

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

[SENSe:]{FREQuency|PERiod}:NULL[:STATe]?

Enables or disables the null function for frequency and period measurements.

This parameter is shared between frequency and period measurements.

Parameter Typical Return

{ON|1|OFF|0}，default OFF 0 (OFF) or 1 (ON)

Configure frequency measurements, using the null function to subtract 1kHz

from the measurements. Make and read two measurements:

CONF:FREQ

FREQ:NULL:STAT ON;VAL 1 kHz

SAMP:COUN 2

READ?

Typical Response： +1.15953012E+02,+1.07954466E+02

 Enabling the scaling function also enables automatic null value selection ([SENSe:]

{FREQuency|PERiod}:NULL:VALue:AUTO ON).

 To set a fixed null value, use this command:

[SENSe:]{FREQuency|PERiod}:NULL:VALue.

 The instrument disables the null function after a Factory Reset (*RST), Instrument

Preset (SYSTem:PRESet), or CONFigure function.
