We adjusted the alignment on ISCTEX and have found a beatnote 
.
The crystal temperature was around 31.7 degC and the beatnote is -50dBm at 42MHz (see picture below).

After some alignment adjustment the beatnote is more like -40dBm. The pll is not locked yet but now we are ready to do the locking from the control room.
