Command Syntax

:SPRocessN:CTLequalizer:GDC{1|2} <low-frequency gain>

<low-frequency 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.

:SPRocessN:CTLequalizer:GDC?

Description

The :SPRocess:CTLequalizer:GDC1 form of this command specifies the low frequency gain (G_dc) applied by an IEEE based CTLE operator. The gain is specified in dB. You can also set the Zero frequency (:SPRocess:CTLequalizer:ZERo), the Low-Frequency Zero/Pole (:SPRocess:CTLequalizer:FZP), and Pole frequency (:SPRocess:CTLequalizer:POLe). For G_dc2, send the :SPRocess:CTLequalizer:GDC2 form of the command. Before selecting this command, send the :FUNCtion:FOPerator CTLE command to first create the operator followed by :SPRocess:CTLequalizer:DEFinition IEEE to define the type of CTLE.

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:GDC 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:GDC
