Description

Specifies tap spacing in taps-per-bit for a Linear Equalizer operator (:FUNCtion:FOPerator FFEQualizer). To select tap spacing in seconds or taps-per-bit, use the :SPRocess:FFEQualizer:TSPacing command. This command is available in both automatic and manual tap configuration mode.

Beginning with FlexDCA revision A.05.60, use of an *OPC? query to pause program execution while waiting for this command to execute.

The Linear Feedforward Equalizer operator is provided with the N1010A-201 Advanced Waveform Analysis license.
