Select Mathematical Expression

Defines the mathematical expression used for mathematical operations. This func- tion equals the nulling function from the front panel.

￿ The data type <expression data> must be typed within parentheses.

Parameters

<expression> is one of the following two mathematical expressions: ((K￿*_X)￿+￿L)￿/￿M or ((K￿/￿X)￿+￿L)￿/￿M No deviations are allowed. K, L and M can be any positive or negative numerical constant, or use XOLD for the last, previously measured value.

Each operand must be surrounded by space characters.

Example

SEND￿:CALC:MATH ￿ (((1 ￿ * ￿ X) ￿ – ￿ 0) ￿ / ￿ XOLD) This example gives a relative result from the last measuring result.

*RST condition:
((( 1 * X ) ￿ 0 ) 1)	(No calculation)
Returned format: <expression>￿
Complies to standards:	SCPI 1991.0 Confirmed.

Enable Mathematics

Switches on/off the mathematical function. Note that the CALCulate subsystem is automatically enabled when MATH operations are switched on. This means that other enabled calculate sub-blocks are indirectly switched on. Switching off mathe- matics, however, does not switch off the CALCulate subsystem.

Parameters:

<Boolean> = ( 1/ON 0/OFF )

Returned syntax: 01

Example

SEND￿:CALC:MATH:STAT ￿ 1

This example switches on mathematics.

*RST condition: OFF

Complies to standards: SCPI 1991.0, confirmed.
