Manual Lock-In
3.2
The first step in manually locking on a solvent when the correct field value is not
known is to search for the lock signal. One approach to finding the lock signal is to
set the sweep amplitude to the maximum (100), increase the lock power (e.g., to 0
dBm), and increase the lock gain (e.g., to 120 dB). The lock DC should be set to ap-
proximately –75 and the sweep rate to 0.2 Hz. Adjust the field value until the lock
signal is approximately centered on the screen, and then begin to reduce the sweep
amplitude. If the signal disappears from the screen during this process, it may be
brought back by re-adjusting the field value. Eventually, the lock signal should be
centered on the screen with the sweep amplitude reduced to a value in the range of 2
to 5. The lock power and gain should also be reduced to a level suitable to the par-
ticular solvent. Finally, the lock phase must be adjusted. The phase is optimized
when the amplitude of the sweep wiggles is the same for both directions of the field
sweep. If the wiggles in one direction are larger than those in the other, adjust the
lock phase to correct the imbalance. Having the correct phase is important to
achieving lock-in.
Caution: Sidebands
It may be difficult, especially if the lock signal is very narrow, to observe the lock
signal when the sweep amplitude is fully open, despite the high power and gain set-
