CALCulate<n>:MATH[:EXPRession]
Syntax:
CALCulate<n>:MATH[:EXPRession] ( <trace_name> <operation>
<trace_name> )
<n> [1] | 2
<trace_name> A trace name which is a predefined
<acquisition_trace> or <memory_trace>.
<acquisition_trace> CH1 | CH2 | CH3 | CH4
<memory_trace> Mi_1 | Mi_2 | Mi_3 | Mi_4
Note: - i = 1 .. 8 (standard memory)
- i = 9 .. 50 (extended memory)
<operation> + | - |
*
Query form:
CALCulate<n>:MATH[:EXPRession]?
Response:
( <trace_name> <operation> <trace_name> )
Description:
This command specifies the mathematical expression for the MATH function. The
operation in the command parameter selects the calculate function, which can be
add (+), subtract (-), or multiply (
*
). Both the source traces in the command
parameter may not be empty. This command does not switch the mathematics
function on; this is done with the CALCulate:MATH:STATe command.
Note: The first trace name can be substituted by the key word IMPLied. In that
case the trace name defined by CALCulate:FEED is applicable.
Limitations:
CH3, CH4, Mi_3, and Mi_4 cannot be used in an expression for the PM33x0B
CombiScope instruments.
Example:
Send
→ CALCulate2:MATH (CH1+CH2) Selects MATH2 channel 1 + 2.
Send
→ CALCulate2:MATH:STATe ON Switches MATH2 function on.
Front panel compliance:
The CALCulate1 and CALCulate2 commands use the MATH1 and MATH2
features of the CombiScope instrument.
