Command Syntax

:FUNCtionN:CRECovery:MODE {CFRequency | ECLock | FOPLl | SOPLl | TOPLl | ZOPLl 
   | EFOPll | ESOPll | ETOPll}

Where N identifies one of sixty four {1:64} math functions that you can create. For example, :FUNCtion2.

Query Syntax

:FUNCtionN:CRECovery:MODE?

Description

Sets the function N Clock Recovery Mode.

CFRequency

Selects the Constant Frequency clock recovery mode. For specifying the Constant Frequency clock recovery mode options, use the :FUNCtion:CRECovery:CFRequency:MODE command.

ECLock

Selects the Explicit Clock clock recovery mode that lets you provide a clock from the circuit that you are measuring. This lets you make a jitter measurement with respect to the provided clock.

FOPLl

Selects the 1st Order PLL clock recovery mode that models the response of an ideal first-order hardware PLL.

SOPLl

Selects the 2nd Order PLL clock recovery mode that models the response of an ideal Type II, second-order hardware PLL.

TOPLl

Selects the 3rd Order PLL clock recovery mode that models the response of an ideal Type III, third-order hardware PLL.

ZOPLl

Selects the 5th Order PLL clock recovery method that is the same as the PCIe 5/6 CXL Behavioral SRIS CC clock recovery methods except that it gives you control over the CDR (clock and data recovery) filter angular frequency parameters ω₀, ω₁, and ω_LF instead of using the values in the PCIe specification.

EFOPll

Selects the Explicit 1st Order PLL clock recovery mode lets you provide a clock from the circuit that you are measuring and apply a first-order PLL.

ESOPll

Selects the Explicit 2nd Order PLL clock recovery mode lets you provide a clock from the circuit that you are measuring and apply a second-order PLL.

ETOPll

Selects the Explicit 3rd Order PLL clock recovery mode lets you provide a clock from the circuit that you are measuring and apply a third-order PLL.
