Chapter 4 Remote Interface Reference
Phase-Lock Commands
UNIT:ANGLe {DEGree|RADian}
UNIT:ANGLe?
Select degrees or radians to set the phase offset value using the
PHAS command (remote interface only). The default is DEG. The :ANGL?
query returns "DEG" or "RAD".
• From the front panel, the phase offset is always displayed in degrees
(radians are not available). If you set the phase offset in radians from
the remote interface and then return to front-panel operation, you will
see that the function generator converts the phase offset to degrees.
PHASe:REFerence
Immediately set the zero-phase reference point without changing the
output of the function generator. This command does not change the
phase offset as set with the PHAS command – it only changes the phase
reference. This command does not have a query form.
PHASe:UNLock:ERRor:STATe {OFF|ON}
PHASe:UNLock:ERRor:STATe?
Disable or enable the function generator from generating an error if
the phase-lock is ever lost. The default is OFF. If the phase-lock is lost
and the error is enabled, a "Reference phase-locked loop is unlocked"
error is generated. The unlock error setting is stored in non-volatile
memory. The :STAT? query returns "0" (OFF) or "1" (ON).
