COMMAND REFERENCE

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.
