[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: +1.0403,+1.0403
l
Enabling the scaling function also enables automatic null value selection (
).
l
To set a fixed null value, use:
[SENSe:]{FREQuency|PERiod}:NULL:VALue
l
The instrument disables the null function after a Factory Reset (
), Instrument Preset
(
), or CONFigure function.
