Query Syntax

:MEASure:RMEMoryN:PLLModel:FZERo?

Where N identifies one of four {1:4} possible JTF response memories. For example, :MEASure:RMEMory3:PLLModel:FZERo?.

Description

Returns the current value for selected Response Memory 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:RMEMory: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:RMEMory:PLLModel:FZERo:STATus?')):
	measurement = Flex.query(':MEASure:RMEMory:PLLModel:FZERo?')

Common Measurement Child Queries
