Internal Oscillator Calibrating and Status
Commands (Option 010 Only)
DIAGnostic:CALibration:ROSCillator:EFC:ABSolute UP | DOWN
This command sets the absolute EFC (electronic frequency control) of
the oscillator.
Use UP or DOWN to adjust the EFC by the increment specified in the
STEP command described below.
For example, if present EFC value is 1000 and STEP value is 13,
DIAG:CAL:ROSC:EFC:ABS:UP will increase the EFC value to 1013.
DIAGnostic:CALibration:ROSCillator:EFC:ABSolute?
This query returns the absolute EFC value of the oscillator.
Returns an integer.
DIAGnostic:CALibration:ROSCillator:EFC:ABSolute:STEP
<numeric_value>
This command sets amount by which the absolute EFC value is
incremented when being adjustment.
Use an integer for the STEP incremental value (<numeric_value>.
For example, if present EFC value is 1000 and STEP value is 13,
DIAG:CAL:ROSC:EFC:ABS:UP will increase the EFC value to 1013.
DIAGnostic:CALibration:ROSCillator:EFC:ABSolute:STEP?
This query returns the incremental step value by which the absolute
EFC value is adjusted.
Returns an integer.
[SOURce]:ROSCillator:QUEStionable?
This query reports if the internal oscillator is producing 10 MHz.
Returns a single character, 0 or 1.
A value of 0 indicates oscillator output is normal.
A value of 1 indicates oscillator output is questionable.
