[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|PERi-
od}:NULL:VALue:AUTO ON).
l To set a fixed null value, use: [SENSe:]{FREQuency|PERiod}:NULL:VALue.
l The instrument disables the null function after a Factory Reset (*RST), Instrument Preset
(SYSTem:PRESet), or CONFigure function.
