Query Syntax

:MEASure:RESPonse:PLLModel:FZERo?

Description

Returns the JTF model waveform's fZero measurement which locates a single frequency in the JTF model where gain decreases. Similar to this is the FPole measurement (:MEASure:RESPonse:PLLModel:FPOLe?) that locates a single frequency in the JTF model where gain increases. A Type 2 PLL by definition has only one pole.

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

Measurement Ready?

To confirm that the measurement is ready to read, you can query the measurement's status:

if ('CORR' in Flex.query(':MEASure:RESPonse:PLLModel:FZERo:STATus?')):
	measurement = Flex.query(':MEASure:RESPonse:PLLModel:FZERo?')
