## Command Syntax

    :FUNCtionN:PARameters:FFT:RIMPedance <ohms>

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.

<ohms> is an integer from 10 to 200.

## Query Syntax

    :FUNCtionN:PARameters:FFT:RIMPedance?

## Description

When the FFT Auto Reference Impedance is off (see `:FUNCtion:PARameters:FFT:AIMPedance`), use this command to specify the reference impedance value.

When the FFT Auto Reference Impedance is on, you can use the query to find the reference impedance value that has been automatically set.
