Syntax :CALCulate:NULL:OFFSet?
:CALCulate:NULL:OFFSet {
|MIN|MAX|DEF}
Function Set the offset of Null operation.
The query returns the offset of Null operation under the current
measurement function in scientific notation.
Explanation  The offset value can hold seven digits after the decimal point.
 The range of is different for different measurement
function.
Measurement Default Unit
DC voltage ±1200 0 V
AC voltage ±900 0 V
DC current ±12 0 A
AC current ±12 0 A
Resistance ±1.2e+08 0 Ω
Capacitance ±2.4e-04 0 F
Frequency 3 - 3.0e+05 0 Hz
Example Set the offset of Null operation under DC voltage measurement to
10.2010031V:
:CALCulate:NULL:OFFSet 10.2010031
The query returns: +1.02010031e+01.
9. :CALCulate:DB:STATe
Syntax
:CALCulate:DB:STATe?
:CALCulate:DB:STATe {ON|OFF|1|0}
Function Enable or disable the dB operation function.
The query returns ON or OFF.
Default OFF
