ADJust?, REFerence | Agilent Technologies E1441A instruction

:ADJust?

PHASe:ADJust? queries the phase offset setting. Returns the phase offset value in radians (even if you specify the phase offset in degrees).

:REFerence

PHASe:REFerence sets the zero-phase reference point upon command execution. This command does not change the phase offset as set with the PHAS:ADJ command but only changes the phase reference. There is no query form to this command e.g., there is no PHAS:REF? command.

:UNLock:ERRor:STATe

PHASe:UNLock:ERRor:STATe OFFON enables or disables the generation of an error if phase-lock is lost. The default setting is disabled (OFF). The setting is stored in volatile memory.

Comments • When you have enabled (ON) the unlock error state and phase-lock is lost, error 580, "Phase-locked loop is unlocked" is generated.

:UNLock:ERRor:STATe?

PHASe:UNLock:ERRor:STATe? queries the state of unlock error generation.

Returns "0" if it is disabled (OFF) or "1" if it is enabled (ON).
