4. Work of NTB-3
NIB-3 receives development tasks fre?om Moscow, via SAG Kabel Headquarters. These tasks
reach the individual laboratories i.p' the form of .technical specifications, in the
German language, of an instrument or-other item to be developed. The technicians in
NTB-3 then build one or more samples of the instrument for despatch to the USSR.
Extensive descriptions, drawings and instructions for -each. item are also assembled
by the Documentation Section for despatch to the USSR with each instrument: this section
employs a number of Russo-German interpreters and translators.
SECRET/CONTROL U.S. OFFICIALS ONLY
IM-3 has about 400 employees. They are headed on the German side by
'one Schlegel (fnu),. a Balt. He speaks perfect Russian. The deputy
director is Axmann (fnu)f who at one time was in the USSR for many years.
The chief engineer is Dr. Weller (fnu).
The organization of NT.B -3 may be shown thus.-

Tasks in Pro Eess in December 1952
a $F Department
1) Development of a spectrometer for the analysis of pulse-modulated HF signals
in the range 9 cros to 6 m (50 mce. to 3,330,mcs.).
2) Development of an apparatus for the analysis of atmospheric disturbances,
3)
Development of a poser meter, for 9 cros. to 6 m. and up to 500 W.
Accuracy 5-10%.
Development of a monitoring frame for monitoring 3 transmitters simultaneously
(uebervachu gsgestell).
Development of a pulse generator,. c- 20.kcs. to 20 mes., for investigation
of ionospheric conditions (similar to work in the Heinrich-Hertz Institute
at Berlin-Adlershof) .
6) Development of an amplitude meter for 1JW.
7) Development of ultrasonic apparatus for material,?testing.
b. Test'lustruments Dept.
Medical apparatus was being developed in this department.
c. Uncertain
The workers in H ?' Dept. understood in December 1952 that aircraft instruments
or apparatus were being developed in other parts of IM-3: but knew no details.
Detailed SxauEp 1 e of a Task.
The Russians laid down the following specifications for the development of a spectrometer,
on which work vas in progress in 1952:
Spectrometer for the analysis of pulse-moffiaated HE' signals in the range 9 ems to 6 a.
(50mes. to 3,330 mos.)-
a.
as
d.
e.
f.
The apparatus must work from -30 C to * 60? C.
It ;at. allow for the analysis of pulses of 0.1 '4
Coaxial 70 ohm input.
Max. input power $ 500 W.
I? amplifier to have bendwii3th of about 20 kes.
Sensitivity of IF' amplifier not less than 50pv,
10 # see
g.
An antenna complex for taking HF oscillations to be included.
h.
50 or 400 cycle feed.
i.
Visual display of the spectrum (CRT).
Photographic recording.

k. Frequency range divided into 3.
1. Weight and. power consumption were also defined.
This apparatus appeared similar to the spectrum analyser produced by the
American firm of Polarad. Use was made in Nei-3 in developing their
spectral analyser, of the work. done by OSW in 1948 - 1949 on a 3 to 12 CID .
spectral analyser.
7. Economic Difficulties
Although the apparatus must be developed as far as possible from East German
materials, certain parts cannot be obtained and members of the staff must `be
sent to West Berlin to buy them with?estmarks. Such items includes
a. Test instruments for ultra-short waves (obtained from Rohde 4 ROM, Munich).
b. Drawn seamless steel tubing.
c. Recently developed vacuum tubes for ultra-short wave and decimeter ranges.
8. 19yelopme Difficulties
a. There is a shortage of qualified staff personnel and those employed are
not always of the highest quality. They often lack a good theoretical
foundation or the possibility of getting it. West German, British and
American literature served in most laboratories as a foundation for much
of the work.
b. When there was some apparent impossibility in the Russian specifications -
as happened from time to time - Russian specialists would come to N' '$-3
to discuss the matter. They were believed to have come from the USSR,
