CALCulate<cnum>:EQUation[:STATe] <bool>
|
(Read-Write) Turns ON and OFF the equation on selected measurement for the specified channel. If the equation is not valid, then processing is not performed. Use CALC:EQUation:VALid? to ensure that the equation is valid. |
|
|
Parameters |
|
|
<cnum> |
Channel number of the measurement. There must be a selected measurement on that channel. If unspecified, <cnum> is set to 1. |
|
<bool> |
ON (or 1) - turns equation ON. OFF (or 0) - turns equation OFF. |
|
Examples |
CALC:EQU 1 calculate2:equation:state 0 |
|
Query Syntax |
CALCulate<cnum>:EQUation[:STATe]? |
|
Return Type |
Boolean |
|
OFF (0) |
|
CALCulate<cnum>:EQUation:TEXT <string>
|
(Read-Write) Specifies an equation or expression to be used on the selected measurement for the specified channel. |

|
<cnum> |
Channel number of the measurement. There must be a selected measurement on that channel. If unspecified, <cnum> is set to 1. |
|
<string> |
Any valid equation or expression. See Equation Editor. |

|
CALCulate<cnum>:EQUation:VALid?
|
(Read-Only) Returns a boolean value to indicate if the current equation on the selected measurement for the specified channel is valid. For equation processing to occur, the equation must be valid and ON (CALC:EQU:STAT 1). |
|
|
Parameters |
