[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
Frequency: -1.2E6 to +1.2E6. Default: 0.
Period: -1.2 to +1.2 seconds. Default: 0.
Configure frequency measurements, using the null function to subtract 1kHz from the measurements.
Make and read two measurements:
