Math Expression

B2961A/B2962A provides a math function for performing calculations using the
measurement result data. The calculation result can be displayed and used for the
trace statistics.
For the predefined math expressions, see
To define a math expression, see Keysight B2961A/B2962A SCPI Command
Reference. Math expressions can be defined by using the :CALC:MATH commands.

Predefined Math Expressions

The following math expressions have already been defined in B2961A/B2962A.
The predefined math expressions are not cleared by the power off and on operations.
• Power (POWER)
• Offset Compensated Ohms (OFFCOMPOHM)
• Varistor Alpha (VARALPHA)
• Voltage Coefficient (VOLTCOEF)
In the following formula, [c] specifies the channel (1 or 2) used for the
measurement.
Calculates power using the following formula.
POWER = VOLT[c] * CURR[c]
Calculates offset compensated ohms (resistance) using the following formula.
OFFCOMPOHM = (VOLT[c][1]-VOLT[c][0]) / (CURR[c][1]-CURR[c][0])
where, VOLT[c][0] and CURR[c][0] are the data measured with a current output
level, and VOLT[c][1] and CURR[c][1] are the data measured with a different
current output level or zero output.
