Command Syntax

:SPRocessN:CTLequalizer:GAIN <gain>

<gain> is a double.

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

:SPRocessN:CTLequalizer:GAIN?

Description

Specifies the DC gain applied by a 2 pole or 3 pole CTLE operator. The CTLE is a first-order transfer function defined by DC gain, zero frequency (:SPRocess:CTLequalizer:ZERo), and two poles (:SPRocess:CTLequalizer:POLe). Before selecting this command, send the :FUNCtion:FOPerator CTLE command to first create the operator followed by :SPRocess:CTLequalizer:DEFinition to define the type of CTLE. To turn on and off the application of the DC gain, use the :SPRocess:CTLequalizer:GAIN:NORMalize command.

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:GAIN 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:GAIN
