2.10 LKM / LKS Options - Supplemental Specifications
The Clock and Lock option enables two or more independent 22531iX power systems to be phase synchronized
to each other. One system (-LKM) acts as the master, the other(s) (-LKS) as auxiliaries. The –LKS units are
synced to the –LKM unit. Refer to section 3.9 for details on Clock and Lock mode.
The following supplemental specifications apply when the 2253iX is configured with the Clock and Lock option. (-
LKM or –LKS).

2.11 RPF Option - Supplemental Specifications
The –RPF option allows an external DC reference to be used to program the output frequency. The following
supplemental specifications apply when the 2253i/iX is configured with the remote programming frequency
option. (-RPF).
Note that loss of input signal while in RPF mode could result in a DC output from the AC source even though it is
in AC mode. If this is potentially damaging to the EUT, care should be taken to always have a minimum input
signal level. See section 3.7.4 for RPF input connection.
