GENERAL
The Model 20-1100 Series Predetection Up Converters consist of seven modules designed
primarily for use in the Model 1100-R/llOO-AR Telemetry Receivers. The modules function
to up convert a video record carrier frequency to 50 MHz for injection into the receiver first
IF signal path. Six of the modules are employed to up convert video carrier signals to 6.8 MHz;
each of the six modules accepts a specific input frequency for conversion to 6.8 MHz. The
seventh module converts the 6.8 MHz signal to 50 MHz. For complete predetection playback
operation, the receiver must be equipped with the 6.8 MHz to 50 MHz converter and the appli
cable video to 6.8 MHz converter. Selection of the video up converter is dependent upon the
video carrier input. Model numbers and the corresponding input frequencies are given below:

INSTALLATION
The units are plugged into parent unit spaces which have been prewired for them and must be
installed in the correct sequence. For example, in the 1100-R series telemetry receivers,
the video to 6. 8 MHz converter must be installed in A18A and the 6.8 MHz to 50 MHz conver
ter must be installed in A18B. The modules are held in place in the receivers by module re
taining clips.
OPERATION
There are no operating procedures applicable to the 20-1100 series converters.
THEORY OF OPERATION
The following description is divided into two parts: that for the video to 6.8 MHz converters,
and that for the 6. 8 to 50 MHz converter. Refer to figures 3 and 4 during the following
discussions.
VIDEO TO 6. 8 MHz CONVERTERS. There are six video to 6.8 MHz converters in the
20-1100 series, each of which converts a specific video record carrier to a 6. 8 MHz carrier.
Since the modules operate in an identical manner, the following circuit description is appli
cable to all. Figure 3 is a schematic diagram of the 900 kHz to 6.8 MHz converter and is
typical of the remaining five modules.
Each module is comp; sed of input amplifier Q7, video amplifier and AGC detector Al, AGC
element Ql, video amplifier Q5-Q6, mixer A2, local oscillator Q2, oscillator control circuit
Q3, oscillator amplifier Q4, and output elliptic function filter L13-L14-L15. See figure 3.
The video carrier input from the recording device is applied through P1-A3, attenuated by
approximately 30 dB, and coupled to amplifier Q7 which, in turn, drives video amplifier/AGC
detector Al. The input signal is applied to pin 9 of Al and fed through a Darlington pair to
the element output atpin 1. From pin 1, the video signal is applied to pin B of the mixer via
a two-stage video driver circuit composed of Q5 and Q6.
A sample of the signal, appearing at the collectors of the Darlington pair, is fed to the AGC
detector portion of Al. The DC output of this circuit is taken from pin 8 and applied to the
AGC element Ql. This transistor functions as a variable resistance with the AGC control
applied to the gate. As the input signal level increases, so does the positive AGC from Al
which decreases the source/drain resistance of Ql causing a larger portion of applied signal
to be shunted out of the signal path. Control of the input signal level is necessary to maintain
a -5 dBm input to the mixer for proper rejection of undesired signals in the passband.
In the mixer, the video signal from Q6 is heterodyned with an input from the local oscillator to
produce a 6.8 MHz output. This signal is filtered by a lowpass, elliptic function filter com
posed of LIS, L14, L15, and associated components. The cutoff frequency of this filter is

ALIGNMENT
The following procedures are recommended for realigning the various modules in the 20-1100
series converters. Because of the interaction between modules, both the video to 6.8 MHz
and the 6. 8 to 50 MHz modules must be aligned together. To properly perform the alignment,
the following equipment should be employed:
Extender Modules
Sweep Generator
Signal Generator
Oscilloscope
VTVM
Spectrum Analyzer
300-355
Texscan VS-80
HP651A
HP1200A
HP414A

OSCILLATOR ADJUSTMENT. The oscillators of both modules are adjusted in an identical
manner. If the oscillator in either module has been repaired, it is only necessary to adjust
that stage. Do not adjust the tuned circuits unless absolutely necessary.
a. Remove the cover and install the module into the receiver
using the extender module.
b. Connect the HP414A to the emitter of the oscillator transistor.
c. Adjust the oscillator coil for a meter null.
d. Disconnect the meter.
TUNED CIRCUIT ADJUSTMENT.
a. Remove the covers and install the modules into the receiver using
the extender modules.
b. Connect the RF output of the VS-80 sweep generator to TPl on the
video converter.
c. Connect the output of the 6.8 to 50 MHz converter to the VIDEO IN
connector of the VS-80.
d. Connect the vertical and horizontal outputs of the VS-80 to the cor
responding inputs of the oscilloscope.
r
e. Set the VS-80 for a 6. 8 MHz output.
f. Adjust the VS-80 output level and the oscilloscope controls for a
convenient display.
g. Adjust coils L13, L14, and L15 on the video converter, and coils
Ll, L3, L6, L7, L8, and L9 on the 50 MHz converter for the re
sponse depicted below. The frequencies of the three reference
points are dependent on the video module installed and are listed
beneath the illustration.

h. Disconnect the sweep generator and oscilloscope.
i. Connect the output of the HP651A to the input of the video converter.
This connection can be made using the receiver rear apron video input.
j. Connect the input of the spectrum analyzer to the output of the 50 MHz
converter.
k. Set the HP651A for an output frequency corresponding to the low end
frequency of the data bandwidth. For example, the 20.1100 (900) data
bandwidth is 1200 kHz or ±600 kHz on either side of the 900 kHz center
frequency. Subtracting 600 kHz from 900 kHz, the low end frequency
is 300 kHz. Set the output level of the HP651A to 2V RMS.
1. Note the amplitude of the main signal compared to the amplitude of the
adjacent responses. The spurious response should be at least 35 dB
below the main signal amplitude.
m. Vary the frequency of the HP651A over the data bandwidth and note that
all spurious responses remain 35 dB down.
n. Reset the generator to the low end frequency.
o. Vary the input level from 0. 35V RMS to 3.1 RMS, and note that the
main signal spike varies less than 2 dB.
p. Disconnect all test equipment and replace the cover.
