Command Syntax

:CRECoveryN:JSANalysis:FFTMagnitude:ECOunt  <count>

<count> is a integer.

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:ECOunt?

Description

Requires an N1060A, N1076A, N1077A, or 86108A/B clock-recovery module that has Option JSA (Jitter Spectrum Analysis and SW Clock Recovery Emulation).

Specifies the number of averages used to smooth the jitter spectrum. The default number of averages is 16. To apply the smoothing, use the :CRECovery1:JSANalysis:FFTMagnitude:SMOothing 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).
