3.7 DIAGnostic Subsystem
This subsystem regroups the queries related to the diagnostic of the OCXO.The list of the commands
supported for this subsystem is as follows:
DIAGnostic:ROSCillator:EFControl:RELative?
DIAGnostic:ROSCillator:EFControl:ABSolute?
DIAGnostic:LIFetime:COUNt?
DIAGnostic?
3.7.1 DIAGnostic:ROSCillator:EFControl:RELative?
This query returns the Electronic Frequency Control (EFC) output value of the internal reference
oscillator. It returns a percentage value between -100% to +100%.
3.7.2 DIAGnostic:ROSCillator:EFControl:ABSolute?
This query returns the Electronic Frequency Control (EFC) output value of the internal reference
oscillator. It returns a value in volts between 0 and 5 V.
3.7.3 DIAGnostic:LIFetime:COUNt?
This command returns the number of hours the unit has been powered-on.
3.7.4 DIAGnostic?
Sending the command DIAG? returns the result of the three following queries:
DIAGnostic:ROSCillator:EFControl:RELative? : Relative oscillator setting
DIAGnostic:ROSCillator:EFControl:ABSolute? : Absolute oscillator setting
DIAGnostic:LIFetime:COUNt? : Time since power-on in hours (lifetime)
