## Command Syntax

    :FUNCtionN:PARameters:DCONvolve:FMODel {ON | OFF | 1 | 0}

Where N identifies one of up to 64 possible operators {1:64} that can be defined as part of a math function. The operators are numbered in the order that they were originally added to the function.

## Query Syntax

    :FUNCtion{1:64}:PARameters:DCONvolve:FMODel?

## Query Response

    {1 | 0}

## Description

Flips the S-parameters input to an Apply S4P operator (`:FUNCtion:FOPerator`). If the S-parameter file's data is not defined with the ports located as shown in the top two diagrams in the following table, flip the S-parameters to ensure that the S-parameter order is properly interpreted. Use the `:FUNCtion:PARameters:DEConvolve:PORDer` command to ensure that the S-parameter port order is also properly interpreted.
