Transposer Tester. This unit may be used to control the
channels, offsets, power, maximum gain and frequency
response of a UHF Television Transposer type TM4M/503.
Control is by means of code switches, toggle switches and
potentiometers and the unit is powered via a 25 way plug
that is used to connect all the controls to the
transposer. The tester also contains a low noise 15V
regulator that may be used to facilitate the testing of
transposer sub-units OS3/509 and AM21/506. Power
requirements +28V and +15V. DD 1980. DDMI 5.409(82).
Automatic Tester. Provides 320 ways of output and 160 ways
of programmable I/O accessed via a 24-line bus. I/O is TTL
level, with 80 outputs available at -50V also. Intended to
interface a microcomputer to a logic unit under test, and
may be interfaced via ports, or directly off the Zeus bus.
Power requirements 240V a.c. mains. Mounted in a suitcase,
450 x 340mm x 200mm. DD 1981. DDHB 2.470(82).
