Command Syntax

:CRECovery{1:8}:JSANalysis:PLLoop:FPOLe  <frequency>

<frequency> is a double.

Where the {1:8} specifier identifies a slot number. 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

:CRECovery{1:8}:JSANalysis:PLLoop:FPOLe?

Description

For a third-order PLL loop, sets the frequency at which the JTF starts to roll-off at 40 dB/decade. To set the frequency at which the OJTF starts to roll-off at 40 dB/decade, use the :CRECovery1:JSANalysis:PLLoop:FZERo command. To enter the frequency that sets the approximate loop bandwidth of the PLL, use the :CRECovery1:JSANalysis:PLLoop:FGAIn command. To select a third-order PLL loop, use the :CRECovery1:JSANalysis:PLLoop:ORDer command.

JTF and OJFT for 3rd Order Type 2 PLLs
with Zero, Pole, and Gain Frequencies

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).
