Function Description
8.1
General
In order to lock on to a substance other than Deuterium options must be built into
the Receiver and Transmitter.
The descriptions in the this chapter deal with 19F as lock substance.
The Receiver functions as straight forward receiver for Deuterium. To lock on to
Fluorine or other substances requires a frequency mixer. The Fluorine frequency
(f
19F
) is created in the transmitter from the Deuterium frequency (f
2H
) mixed with
an auxiliary frequency (f
AUX
= f
2H
+- 1MHz + f
19F
). Using the same auxiliary fre-
quency the Fluorine signal is converted back to the Deuterium frequency range in
the receiver option.
The same connection (X_REC) from the preamp to the receiver is used for the 19F-
Signal as for the 2H signal. We therefore require switching to the option at the input
and output.
Figure 13: Signal path in Receiver with built in Option.
Trouble free upgrades to optional lock are available on-site. Upgrading to Fluorine
requires alterations to the transmitter as well as the receiver.
Concept
The Option has the transfer characteristics of a bandpass filter (see following block
diagram).
On the one hand the Lowpass section suppresses the mixer disturbances from the
19F-LO (X_LO) and 19F-RF (X_REC) and on the other hand the highpass section
