Command Syntax

:SPRocessN:CTLequalizer:DEFinition {POLE2 | POLE3 | GAIN2}

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. The following table lists the child commands available for the three CTLE definitions.

:SPRocessN:CTLequalizer:DEFinition?

Query Response

{POLE2 | POLE3 | IEEE}

Description

Specifies the type of Continuous Time Linear Equalizer (CTLE) operator. You can select a 2 pole CTLE (POLE2), a 3 pole CTLE (POLE3), or a CTLE based on the IEEE 802.3ck standard (GAIN2). The following tables show the valid child commands for configuring the CTLE based on the CTLE's definition as set by this command. Be sure to look at the available factory presets that can be selected with :CTLequalizer:PRESet. To configure the filter's Aliased Noise Processing, use the :SPRocess:CTLequalizer:PNOise command.

Before selecting the type of CTLE, send the :FUNCtion:FOPerator CTLE command to first create the operator.

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:DEFinition 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:
