:SPRocess:CTLequalizer:ZERO

Command Syntax

:SPRocessN:CTLequalizer:ZERO{1|2} <zero_frequency>

<zero_frequency> 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:ZERO?

Description

Specifies the zero frequency of a continuous Time Linear Equalizer (CTLE) operator (:FUNCtion:FOPerator CTLE). For a two or three pole CTLE, use :ZERO1 to enter the Zero 1 frequency. For a three pole CTLE, use :ZERO2 to enter the Zero 2 frequency. The CTLE is a first-order transfer function defined by DC gain (:SPRocess:CTLequalizer:GAIN), zero frequency, and two or three poles (:SPRocess:CTLequalizer:POLe). Use the :SPRocess:CTLequalizer:DEFinition command to select the type of CTLE operator.
