SIGNALlab SCPI enable external clock

Is there a SCPI command or other userfriendly way to enable the external clock in the SIGNALlab 250-12? I've seen a switch in the browser-apps, so I'd assume it'd be possible to do this over SCPI.

After a lot of digging through the API, I found the methods
Code: Select all
int rp_GetPllControlEnable(bool *enable)
int rp_SetPllControlEnable(bool enable)
int rp_GetPllControlLocked(bool *status)
As the PLL is internally connected to the ref-input-clock, I assume that this is what I searched for.
I will soon test this and also write functions for the SCPI server, push that to my git repository and link it here for people to use.
Another way to activate and read the external clock is to use the monitoring tool modifying the according register (see docu).
