:CHANnel<X>:MATH
Set the math expression.
Syntax
:CHANnel<X>:MATH {0|1|2|3}
Arguments
<X>→Specify the channel number (1|2)
0→Select the add operator 1→Select the subtract operator
2→Select the FFT operation 3→Turn off math function
Returns
<NR1>
:CHANnel<X>:OFFSet
Sets or query the offset voltage.
Syntax
:CHANnel<X>:OFFSet <NR3>
:CHANnel<X>:OFFSet?
Arguments
<X>→Specify the channel number (1|2)
<NR3> is the desired offset value in volts. The range is dependent on the scale and
the probe attenuation factor. The offset ranges are following:
Offset Range:
2mV/div ~ 50mV/div
±0.5V
100mV/div ~ 500mV/div
±5V
1V/div ~ 5V/div
±50V
