To Install CTLE Operator

Use this command:

:FUNCtion:FOPerator CTLequalizer

If secondary to Reference Rx operator:

:FUNCtion:SOP2 CTLequalizer

Command Syntax

:SPRocessN:CTLequalizer:PRESets <preset name>

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.

<preset name> is a string.

Description

Loads a previously saved settings known as a preset for a Continuous Time Linear Equalizer (CTLE) operator. The preset configures the operator to your saved settings. To query which presets are available for loading, use the PRESets:SELections? query.

For Reference Rx operator, what function do I send this command to?

If the CTLE equalizer is a secondary function to the Reference Rx operator, address the :SPRocess:CTLequalizer:PRESets command to the Reference Rx function as identified in the following Reference Rx Setup dialog's operator diagram. In the following figure, this would be Function 2 and the command would be:

:SPRocess2:CTLequalizer:PRESets

Requires FlexDCA revision A.04.50 and above.

Example Commands

:SPRocess:CTLequalizer:PRESets "OIF CEI-28G-VSR (3db)"  //  Load a factory provided preset.
:SPRocess:CTLequalizer:PRESets "MyPreset"  //  Load your saved preset.
:SPRocess:CTLequalizer:PRESets:SELections?  //  Get list of saved presets.
