Digital-Analog Converter (DAC)
5.1.9
The transmitter level controlling signal is produced in a DAC (IC5). This DAC is
controlled by the Serial Bus and IC3 (OP) converts the current output of the DAC
into a proportional voltage. The transmitter power range is adjusted via the Potenti-
ometers POT2 and POT3. Thereafter the transmitter maximum power is first set
with POT2 and then the minimum power with POT3. Both of the temperature sen-
sors IC31 and IC32 are compensating the transmitter gain temperature drift. IC31
corrects the gain elevation angle drift and IC32 the gain offset drift.
A second DAC (IC1) may be used for switching and is quickly set via a 7 Bit Bus
(EPROM_BUS). Because the In and Out Flanking of the transmitter pulse is con-
trolled by this DAC the transmitter pulses are able to be generated in different
shapes. The different shape forms are stored in the EPROM.
An OP (IC3) adds both of the DAC signals and delivers the control signal UAGC.
This is possible because the control voltage UAGC acts in a linear fashion upon the
transmitter power. The Zener Diode limits the UAGC to a maximum of 12 V.
PFP / FFA-Mode Switching
5.1.10
The transmitter signal from the AGC amplifier is divided after the amplifier MOD1.
One part is used for the X-Option (e.g. 19F); the other part is amplified again in
MOD2. In normal lock operation (PFP Mode) the transmitter signal is switched us-
ing IC4 and sent via L19 to the transmitter output (J3). Therefore C79, L19 and
C119 act as a quarter wave. The print version ECL01 has an additional attenuator
between the switch IC4 and L19 to reduce the transmitter signal. Thus the output
level at J4 is 10dB less then the level of version ECL00. The recitfied transmitter
signal may be used for diagnostics via the DIAG_1 connection.
In FFA mode IC4 switches the signal to the FFA amplifier (T7). IC4 is controlled by
a TTL signal via the FFA connection. A logic high level switches on the FFA ampli-
fier supply voltage.
If there is a lock substance other than Deuterium used the control connection
L_SUBST is logic high. This switches the two Deuterium transmitter signals off.
