[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.
Unlike the SENSe:FREQuency and SENSe:PERiod range and aperture commands, this parameter is not
shared between frequency and period measurements. The null parameters are independent for
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: +1.04530000E+03,+1.04570000E+03
l Enabling the scaling function also enables automatic null value selection ([SENSe:]
{FREQuency|PERiod}:NULL:VALue:AUTO ON).
l To set a fixed null value, use this command: [SENSe:]{FREQuency|PERiod}:NULL:VALue.
l The instrument disables the null function after a Factory Reset (*RST), Instrument Preset (SYSTem:PRESet), or
CONFigure function.
[SENSe:]{FREQuency|PERiod}:NULL:VALue {<value>|MIN|MAX|DEF}
[SENSe:]{FREQuency|PERiod}:NULL:VALue? [{MIN|MAX|DEF}]
Stores a null value for frequency and period measurements.
Unlike the SENSe:FREQuency and SENSe:PERiod range and aperture commands, this parameter is not
shared between frequency and period measurements. The null parameters are independent for
frequency and period measurements.
Parameter Typical Return
-1.2E6 to +1.2E6, default 0 +1.00000000E-02
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: +1.04530000E+03,+1.04570000E+03
l Specifying a null value disables automatic null value selection ([SENSe:]{FREQuency|PERiod}:NULL:VALue:AUTO
OFF).
l To use the null value, the null state must be on ([SENSe:]{FREQuency|PERiod}:NULL:STATe ON).
l This parameter is set to its default value after a Factory Reset (*RST), Instrument Preset (SYSTem:PRESet), or
CONFigure function.
