Command Syntax

:CRECoveryN:JSANalysis:FFTMagnitude:SMOothing  {NONe | AVERage}

Where N identifies the slot number and must be selected from {1:8}. The slot number is associated with the N1060A, N1076A/B, N1077A, N1078A, or 86108B module with Option JSA. When an 86108B module is used, the slot number is always 1.

Query Syntax

:CRECoveryN:JSANalysis:FFTMagnitude:SMOothing?

The query response is {NON | AVER}.

Description

Applies average spectrum smoothing to the jitter spectrum. To specify the average count, use the :CRECovery1:JSANalysis:FFTMagnitude:ECOunt command. To select the input signal's location in the clock-recovery circuit from which to construct the jitter spectrum, use the :CRECovery1:JSANalysis:SPECtrum command.

Requires FlexDCA revision A.01.70 and above.

Requires a clock-recovery module that has Option JSA (Jitter Spectrum Analysis and SW Clock Recovery Emulation).
